Shallow buns are suitable for planting in many areas. How do you plant shrubs in dry land? What is the method of planting shrubs in dry land? Today, Pesticide First Network Xiaobian came to tell everyone about the cultivation method of dryland shrubs.
Variety selection
Should be selected in the early stage of low temperature resistance, strong growth potential, high yield and high quality varieties. The pod species should be selected from two sub-sections that are large in size and robust in axillary buds, and have no pests and diseases and have the characteristics of this species.
Digging Jianchi
Select a place where there is a certain water source. Dianchi Lake is generally square or rectangular and has an area of ​​300 to 600 square meters.
First excavate with artificial or bulldozers, depth 50 cm ~ 60 cm, then leveling the bottom compacted, and then a layer of waterproof plastic film, pool depth of about 80 cm, of which, 50 cm below ground level, 30 cm above ground level. Retain the water hole at the end of the water source, and leave the drain hole at the other end. The entire Dianchi pond needs to be flat and firm without leakage of water and no leakage of fat.
Backfill fertilization
Generally, 4000 to 5,000 kg of chicken manure is fully cooked per mu, 100 kg of cooked cake fat, 50 kg of diammonium phosphate, 50 kg of potassium sulfate, 30 kg of urea or 100 kg to 125 kg of ternary compound fertilizer, and evenly mixed with Datian soil. Backfilled into Dianchi Lake, with a thickness of 30 cm.
Transplantation
Before and after Gu Yu (April 15 ~ 25) sowing is appropriate, with 250 kg to 300 kg per acre, before sowing with 45% of chlorothalonil or 50% of carbendazim 600 times soaking for 10 minutes to sterilize disinfection. The directions of the planting are to be arranged in an alternating manner. One plant heading south, one plant heading north, and the steamed buns around Dianchi Lake are all facing the pool, which is conducive to the even distribution of the whip in the later period. Drain 3 cm to 5 cm, and then rake the seeds downwards into the mud, soak the dew to the surface of the water, soak it after sowing, and maintain a shallow water layer of 8 cm to 10 cm to raise the temperature and promote bud germination. .
Field management
The initial water level is maintained at 8 to 10 cm. After warming up in the beginning of summer, the amount of evaporation is large, and the water level should be kept at 20 cm. During the summer, the lotus root grows rapidly and the water level should be maintained at 40-50 cm. After the autumnal equinox, the shoots grow slowly, and the photosynthate accumulates underground, which is transferred to the starch growth stage. The shallow water level should be kept between 5 and 8 cm.
Plant adjustment, removal of floating leaves, a month or so after planting, floating leaves yellow withered, should be removed to increase light to increase water temperature. The peduncle is twisted, and the pedicel is twisted when the bud takes place, but it cannot be broken to reduce nutrient consumption and increase yield. Turning gimmicks to enter the peak of growth, lotus root grows faster, when the leaf is near the field edge, the hoe should be transferred to the field in time.
According to the law of growth and development of lotus root, two key fertilizers should be applied. The first time after sowing 30 to 40 days, that is, when the second three tablets of liquids appear, 40 kg of Sanyuan compound fertilizer will be applied, and the second time will be later. In the week before the leaves were unfolded, some of the lotus plants had been opened. At the early stage of sitting and sitting, urea 15 to 25 kilograms of urea and 5 to 10 kilograms of ternary compound fertilizer were mixed and sprinkled into the pool. Before each dressing, shallow water should be released, and the water level should be restored after 4 to 5 days.
Shrub cultivation in drylands: Pest control
Corruption disease can be controlled by 50% carbendazim WP 500 times plus 75% chlorothalonil wettable powder 500 times spray, also can be used 1:1 mixture of the above two drugs, 500 grams per acre plus soil 25 to 30 kg, heap Bored 3 to 4 hours, thrown into the shallow water layer. Mites can be treated with 40% of Dimethoate 1000 times.
