When is the right time to grow Liliaceae garlic? How can we produce high yields? When will the harvest be ripe?

Garlic, also known as garlic, garlic. So when is it right to grow? How can we produce high yields? When will it be ripe for harvest? According to Uncle Guo of Linyi, Shandong Province, garlic is more suitable for planting in autumn, usually around mid-September. Planting garlic in autumn in the north is generally carried out from late September to early October. Henan, Shandong and other places were planted in September.

How can garlic be planted with high yield?

First, attach importance to the selection and retention of species and maintain the seed character of "Jiading White garlic".

Before sowing, choose "Jiading White garlic", which is enlarged cloves (about 5 grams per clove) and 8 cloves, which is disease-free, insect-free, mildew-free and knife-free.

Second, apply sufficient basic fertilizer and make fine soil preparation.

Before sowing, the field should be ploughed deeply and carefully, so that the border surface should be flat and the ditch system should be matched. In general, the bed is 2.1 meters wide and the ditch is 25 meters deep and 30 centimeters deep, and the transverse and lumbar grooves should be well opened. At the same time, it is necessary to apply sufficient base fertilizer, about 500 kg of commercial organic fertilizer per mu, 25 kg of special fertilizer for garlic and 10 kg of potassium chloride. Fertilizer should be applied before ploughing to achieve the mixing of soil fertilizer and improve fertilizer efficiency. Fertilizer should not be applied directly in the sowing ditch to prevent burns of roots and buds from breaking ridges and lacking seedlings.

Third, adhere to timely sowing and moist emergence of seedlings

Timely sowing is one of the important measures for high quality and high yield of garlic. Early sowing not only affects the previous crop, but also prone to the phenomenon of "double growth" (some places are called flowering garlic, horsetail garlic and bearded garlic). Sowing too late can not ensure that strong seedlings survive the winter, affect the growth and development of bolting and garlic, and reduce the yield. According to the climatic conditions of Jiading District in recent years, it is appropriate to sow seeds from the end of September to the first ten days of October.

In case of dry weather in the sowing season, drought resistance should be carried out before or after sowing to keep the soil moist at the seedling stage. In case of continuous rain for a long time, the ditch system should be cleaned in time to eliminate stagnant water in the field and prevent rotten seeds.

Fourth, reasonable close planting to increase the type of garlic.

The sowing density is directly related to the yield and size of garlic. The results of research and practice of high-yield garlic households for many years show that the reasonable density is 2.0-22000 plants / mu, that is, the row spacing is 33-36 cm, and the plant spacing is 8-9 cm.

Chemical weeding

Before sowing seedlings, use 50% diachlor 100 grams per mu or 33% herbicide 100ml 150 ml, spray with water to kill pre-winter weeds. After the beginning of spring, the temperature rebounded (early March). After clearing the weeds in the fields, 33% paddy fields were used to replenish (herbicide) 100ml / mu. Fields with broad-leaved weeds should be added with 10.8% efficient grass cover energy EC45ml per mu and sprayed with water to block weeds after spring.

VI. Strengthen pre-winter management and cultivate strong seedlings

Garlic seedlings grow excessively before winter and are easy to suffer frost injury, and are prone to premature senescence and secondary growth. Overwintering seedlings should be short and strong, but not thriving, and the measures are as follows:

① applied seedling fertilizer early, and immediately after finishing the seedlings, urea was applied to 8 kg per mu.

② increased the application of phosphorus and potassium fertilizer, 25 kg of phosphate fertilizer, 10 kg of potassium fertilizer or 50 kg of compound fertilizer per mu.

Pay attention to winter tube to ensure that garlic seedlings survive the winter safely

① heavy application of wax fertilizer: wax fertilizer is mainly organic fertilizer, organic fertilizer has all nutrients, stable fertilizer effect and long fertility, which can improve the ability of water storage and fertilizer conservation. Generally, 25 kilograms of cooked pig, sheep and rabbit ash is applied per mu, and 25 kilograms of garlic special fertilizer can be applied if the organic fertilizer is insufficient.

② loosens soil, weeds and cultivates soil choking roots to promote root growth.

③ cleaning ditch system: garlic likes wet and afraid of soiling, and the soil water content is high, which will affect the root growth and development. therefore, we must quickly clean up the gully system to achieve communication between ditches, and to clean and deepen the horizontal ditch and Daming ditch to ensure smooth drainage and irrigation, improve the ability of disaster resistance, and ensure the high and stable yield of garlic.

8. Do a good job in spring management and build a high-yield shelf

Strong individuals are the basis of high quality and high yield. The Spring Festival management should focus on three management tasks:

① applied spring fertilizer to promote early development, usually from the end of February to the beginning of March, applying 8Mel 10 kg of urea per mu.

② dredges the ditch system so that it can be irrigated in case of drought and drained by rain, regulate soil moisture and promote the growth of garlic seedlings.

③ sprayed 33% Caocaotong (paddy field tonic) emulsion 100ml in early March.

Strengthen the management in the later stage, enhance the stamina, and give full play to the role of functional leaves.

The growth of garlic in the later stage is closely related to the yield and quality of garlic. Three key measures should be taken.

① re-applied moss fertilizer and long-head fertilizer, about 15 kg urea per mu in late March and 20 kg per mu in late April.

② controls the disease from late March to early May, depending on the occurrence of the disease, every 5 days or so. For the first time, three or two carbendazim per mu was sprayed with water, and the second was sprayed with three or two carbendazim plus jinggangmycin per mu to control the occurrence and spread of the disease, prevent premature senility and protect functional green leaves.

③ regulates soil moisture and promotes the expansion of garlic. During the expansion period, drought should be resisted in time, which has an obvious effect on the yield increase of garlic.

X. timely harvest to improve the yield and quality of garlic

① should pick moss at the right time to avoid hurting green leaves.

② harvested garlic in time to prolong the functional period of green leaves.

When will garlic be ripe and harvested?

The growth cycle of garlic varies greatly with different sowing dates. The growth period of spring sowing garlic is only 90 ~ 100 days, while that of autumn sowing garlic is 220 ~ 280 days. The harvest time of garlic is about 20 days after picking moss, and there are about 4 green leaves per plant, usually from May 25 to early June.
