After the garlic returns to the green hair, it enters the rapid growth period, especially during the pregnancy period and the garlic expansion period. The demand for water and fertilizer is greatly increased, the pests and diseases enter the high-incidence period, scientifically grasp the "three water, three fertilizers, two prevention and treatment", the later garlic wants Not high yields are difficult.
One, three water + three fertilizer
1. Pouring the green water and applying the green fertilizer
In early spring, the garlic seedlings enter the rejuvenation stage. At this time, the ground temperature is low, and the returning green water is best applied at noon to promote the early growth of the garlic seedlings. It can be applied with 20 kg/mu of NPK fertilizer or 15 kg/mu of potassium sulphate when pouring back into Qingshui, and appropriate water control to promote the development of garlic roots and the differentiation of garlic and garlic.
2, pouring enough water to promote the use of water
Garlic entered the flower bud differentiation period in March and April. Garlic and garlic also entered the rapid growth period. The garlic stalks grew rapidly, and the demand for water and fertilizer increased sharply. The management of water and fertilizer at this time directly affected the yield of garlic and garlic. At this time, watering needs to be done once a week, 25 kg/mu of NPK fertilizer per half month, or 15 kg/mu of urea, phosphorus and potassium compound fertilizer, or foliar fertilizer for fertilizer supplementation.
3, pouring enough water to expand, skillfully applying bulk fat
After the garlic is picked, it enters the period of expansion of the garlic. At this time, it is necessary to timely water the fertilizer to prevent premature aging of the garlic leaves and promote the accumulation of nutrients in the garlic. At this time, it is necessary to maintain timely watering to maintain the humidity of the soil until the garlic is received one week before the harvest. The topdressing fertilizer is mainly available nitrogen fertilizer, supplemented by phosphorus and potassium, and can be applied with urea or potassium sulfate compound fertilizer 20 kg/mu.
In addition, for heavy plots, organic fertilizer should be applied as a base fertilizer to improve soil conditions, and attention should be paid to the supplement of trace elements such as sulfur, calcium, magnesium and boron to reduce the occurrence of garlic physiological diseases. If you want more comprehensive and accurate fertilization, you can use the method of soil testing and fertilization.
Two or two prevention
The prevention and control of pests and diseases should adopt the method of “prevention and prevention combined with prevention and controlâ€, so that prevention in the early stage does not occur, and the later management does not spread.
1, pest control
Onion horses, locusts and garlic mites are easy-to-obtain pests of garlic. They can be sprayed with 1% matrine soluble liquid to control onion horses and mites, and they can be used to control garlic ash in the period of garlic seedlings.
2, prevent disease
Leaf blight, purple spot disease, root rot, etc. are common diseases of garlic, and can be implemented by changing rotation, fine selection, and controlling the field. For the plots that have already occurred, 70% of mancozeb WP 600 times or 90% Ethyl aluminum 500 times solution can be used to control leaf blight, using 64% anti-virus WP 1500 times or 50% The bactericidal wettable powder 600 times liquid is used to prevent and control purple spot disease, and root rot is prevented by rooting with biogreen Trichoderma or 600-800 times liquid.
