When does garlic grow garlic cultivation technology?

When is garlic planted with garlic cultivation technology? Garlic can be said to be a must-have item in life. It contains a variety of vitamins, trace elements and other nutrients. It also has a good health care effect and has been favored by the masses. In view of the strong demand in the garlic market, farmers have chosen to grow garlic. So, when is garlic planted with garlic cultivation technology?

Garlic planting time:

Garlic likes cold weather conditions, the suitable temperature for growing stems and leaves on the ground is 12-16 °C, and the best seedling age for seedlings overwintering is 4-6 leaf stage. It takes about 40-45 days from sowing to 4-6 leaves. The growth is stopped when the average daily temperature is below 7 °C.

The seedlings are strong in cold resistance and can withstand low temperatures of -7 to -10 °C. At 0-4 ° C, the vernalization stage can be passed through 30-40 days. The suitable sowing date for the autumn-sown garlic in the open field is from late September to early October (around the morning cold after the autumn minute). The sowing is early, and it is easy to be frozen. Due to the late high temperature, the production period is shortened, the yield is low, and the quality is poor.

Garlic planting technology:

First, the watering of garlic:

Although garlic leaves have strong drought tolerance, the roots are shallow and the absorption capacity is weak. Therefore, garlic requires higher soil moisture, and different growth periods have different requirements on soil moisture.

1. Maintain high soil moisture after sowing of garlic. If it is too dry, it should be watered in advance to achieve suitable planting. Generally, no water is poured before winter, and roots and seedlings are promoted.

2. After the garlic is returned to the green fertilizer in the following year, it is necessary to fill the head water. This is the key to increasing the yield of garlic and garlic.

3, in the garlic seedlings to maintain the soil see dry and wet, can promote root growth and development.

4. After the garlic seedling stage, the soil moisture requirement is gradually increased. During the twitching period and the bulb expansion period, the requirement for soil moisture reaches a peak. The farmer's “to eat garlic and mix in the mud” is the reason.

5. In the later stage of garlic bulb development, the water requirement should be reduced rapidly. The watering should be controlled to promote the ripening of the phosphorus stem and improve the storability of the garlic.

Second, the fertilization of garlic:

Garlic can be fertilized according to the characteristics of growth and development, fertilizer and fertilizer. Garlic fertilization should be based on organic fertilizer and supplemented by chemical fertilizer. The principle of fertilization supplemented by base fertilizer and topdressing should be used to maximize the growth and development of garlic. The need for nutrients. Fertilization of garlic is generally divided into base fertilizer and topdressing. The following is a detailed introduction.

1, the base fertilizer of garlic:

The base fertilizer of garlic is best based on organic fertilizer. Common organic fertilizers include ring fertilizer, chicken manure, duck manure, manure, compost, and cake fertilizer. Whether the application amount of the base fertilizer is sufficient is directly related to the commercial nature of the garlic and the wintering performance of the plant, so the base fertilizer should be applied in production.

The application rate of the base fertilizer should be determined based on various factors such as the target yield of garlic and the amount of fertilizer required per unit area. Conditional application of cottonseed cake and other cake fertilizer 50-100 kg. The chemical fertilizer applied with the organic fertilizer as the base fertilizer usually has superphosphate, nitrogen and phosphorus compound fertilizer, nitrogen-potassium compound fertilizer or ternary compound fertilizer. Apply about 75 kg of standard nitrogen fertilizer per 667 square meters.

Nitrogen fertilizer should be applied 2/3 as base fertilizer and 1/3 as top dressing. Most of the phosphorus and potassium fertilizers are applied as base fertilizers. Phosphate fertilizer uses about 30 kg of superphosphate. When phosphate fertilizer is applied as base fertilizer, whether it is superphosphate or calcium magnesium phosphate, it should be mixed with organic fertilizer and shallow tilled into the plough layer. The amount of potassium fertilizer applied is generally about 30 kg of potassium sulfate per 667 square meters.

The application of base fertilizer is generally to apply half of the organic fertilizer before the cultivated land, spread it evenly on the surface of the soil, combine the cultivated land, and turn the fertilizer into the ground; the other half concentrates on the ditch when planting, and makes the fertilizer and soil phase Mix and then sow. For example, when ammonium bicarbonate or organic fertilizer is used as the base fertilizer, it should be ditched or applied with water, and combined with the soil preparation after application, the fertilizer and the soil are evenly mixed.

The application of phosphate fertilizer is preferably shallow, concentrated or layered. One can apply a part before the cultivated land, the other part is applied when the garlic is cultivated after ploughing, or it can be applied to the ground 6-10 cm after the soil preparation to facilitate the absorption and utilization of the seedlings, cultivate the strong seedlings, and improve the utilization rate of the phosphate fertilizer in the current season. Potassium fertilizer can be used in the arable land, with the arable land, and can be turned into the ground.

Summary of the cultivation time of garlic and the technical points of fertilization

2, garlic top dressing:

From the seedling stage of garlic to the various growth stages before bulb harvesting, according to its growth and development, fertilizer and fertilizer characteristics, fertilization is carried out in stages, which is topdressing.

The topdressing of garlic is mainly based on nitrogen fertilizer. When necessary, nitrogen, phosphorus, potassium fertilizer and various elements should be applied together, which is beneficial to the normal growth and development of garlic, and is beneficial to promoting the absorption and utilization of nutrients and improving quality. Nitrogen fertilizer has a significant yield-increasing effect on garlic.

When applying nitrogen fertilizer to garlic, attention should be paid to the possible adverse effects. According to experiments, the effect of nitrogen fertilizer application is closely related to the size of garlic cloves. The smaller the garlic cloves, the greater the yield of nitrogen application. Therefore, when using small cloves for garlic, the application amount of nitrogen fertilizer should be appropriately increased.

The application of phosphate fertilizer and potassium fertilizer can increase the balanced absorption and utilization of nitrogen fertilizer, promote the growth and development of garlic, and increase the yield of garlic and garlic. In the later stage of garlic, not only the nitrogen fertilizer should be applied, but also the phosphorus and potassium fertilizers should be applied. The nitrogen, phosphorus and potassium fertilizer should be applied in a ratio of 2:1:1 or compound fertilizer. This is beneficial to prevent premature senescence of the leaves in the late stage of garlic and promote the transportation of leaf nutrients to the bulbs, which can significantly increase the yield of garlic and garlic.

The topdressing period can be generally divided into topdressing before wintering, topdressing during greening, topdressing in garlic, and topdressing in garlic.

Top dressing of garlic before winter: The top dressing before wintering is mainly to promote the normal germination and emergence of garlic, and to cultivate strong seedlings. The appearance of strong seedlings before winter is: there are 5 leaves, the plant height is about 25 centimeters, the fresh weight per plant is about 10g, and the roots are even, about 30. After the autumn sowing garlic is planted, it can be used for 7-9 days. In order to improve the safe winter performance of garlic, the seedling fertilizer is applied. The seedling fertilizer generally accounts for about 25% of the total topdressing amount. Varieties that are prone to outer-type cross growth, should be applied less or not.

When the garlic enters the wintering period, it can be applied to the winter fertilizer, that is, the wax fertilizer. The fertilizer is commonly used for composting, soil-fertilizer or horse manure to thicken the wintering protective layer of the root system, improve the wintering performance of the seedlings, and ensure safe wintering. At the same time, it is also conducive to early return to the next year, fast growth.

Garlic dressing in the greening period: When the average daily temperature in spring reaches 7 degrees Celsius, the garlic seedlings begin to grow green. At this time, the cover should be removed in time, and the seedlings should be dried for 2-3 days. Before the spring leaves grow, the seedlings should be followed up. . Generally, 1000-1500 kg of organic fertilizer is applied per 667 square meters, or 10-15 kg of standard nitrogen fertilizer. For those who have already applied the seedling fertilizer and the wintering fertilizer, the greening period may not be followed by the topdressing, or the greening fertilizer may be postponed to be combined with the stimulating fertilizer.

The top dressing of garlic garlic stalks: the garlic stalks during the elongation period refers to the top dressing from the garlic stalks to the top dressing before the hoeing. This period is the period when garlic and garlic grow and enter. In Shandong, it is usually at the end of March and early April, that is, before the Qingming, the garlic enters the differentiation period of garlic and garlic. On May 20, it is into the convulsion period before and after Xiaoman.

Because the elongation of garlic and the pre-growth of garlic are overlapping, it is in a period of vigorous growth. At this time, all the leaves have grown, the growth of the aboveground part of the plant reached the maximum, the yield of the garlic in the underground part has formed close to 50%, the root system actively expands horizontally, and the growth and absorption gradually reach the peak, so the top dressing should account for the total top dressing. About 40% of the amount. It is necessary to increase the application of compound fertilizer and potassium fertilizer to promote the expansion of garlic convulsions and garlic.

Garlic garlic topdressing: Since garlic is harvested before harvesting, the growth of garlic is mainly based on increasing volume. After harvesting garlic, the growth of garlic is mainly based on weight gain. The average daily gain is about 1g, and the daily diameter is 0.06. About centimeters. In the growing season of garlic, the main effect of nitrogen fertilizer should be combined with phosphorus and potassium fertilizer. The amount of topdressing should account for 25%-30% of the total topdressing.

Garlic topdressing method: generally applied, applied with water or buried. When applying soil fertilizer, it can be ditched and sprinkled into strips; when applying chemical fertilizer, it is generally applied by ditching or hole application, after applying soil, watering, or pouring with water, or spraying with rain. . Attention should be paid to strengthening cultivating and weeding, keeping soil loose and lyrical, so as to accelerate the absorption and utilization of nutrients by roots.
