Shallow land shrub planting in dryland is a new and efficient planting model. It has the characteristics of thrifty land, water saving, simple management, low investment, low risk, and quick effect. Once invested for many years, Zoucheng Chengqian Town promotes 65 hectares for two years. Usually produce 藕2500kg to 3500kg per 667 square meters, and the income is between 5,000 yuan and 7,000 yuan. The main cultivation techniques are as follows: 1, digging Jianchi Choose a desolation beach, river beach, waste pit or wasteland with a certain water source and convenient transportation. The area of ​​Dianchi Lake is usually 300-600 square meters. First excavate with artificial or bulldozers, depth 50 cm -60 cm, then level the bottom of the compaction, and then spread a layer of 0.1 mm film, and finally smooth with 1 cm -1.5 cm thick cement. The pool wall is surrounded by bricks or hollow bricks. The depth of the pool is about 80 cm, of which 50 cm below the ground level and 30 cm above the ground level. Relying on the water source to stay in the water hole, leaving the other end of the drainage hole, 40 cm -50 cm from the bottom of the pool, all Dianchi pond begs flat and firm, no water leakage, no leakage of fat. 2, backfill fertilization Usually 4,000 to 5,000 square meters of fully decomposed chicken manure, 100 ton of cooked cake, 50 kg of diammonium phosphate, 50 kg of potassium sulfate, 30 kg of urea, or 100 to 125 kg of ternary compound fertilizer, and Daejeon The mixture was evenly backfilled into a dike pool and the thickness was 30 cm. After that, press the standard of 22 meters to pick the soil layer along the line with a shovel, put the tiles or bricks on the bottom of the pool, lay it flat and straight, and use soil to plug it tightly to control the growth of the whip and increase the output. 3, species selection Should choose the early period more resistant to low temperature, strong growth potential, high yield and high quality E Lian 4 and E Lian No. 5, etc., pods to choose large pieces of intact, axillary buds have more than two strong, no pests and have the characteristics of this species For the species. 4, suitable for transplanting It is advisable to sow at 10°C-12°C with the local geothermal temperature, ie before and after the rain (April 15-25). Usually planted at a plant spacing of 11.5-2.0, 1 plant per plant, 2 plantlets, 250-300 kg for 667 m2, 600-fold for 45% chlorothalonil or 50% carbendazim before sowing. Soak the seeds for 10 minutes to sterilize. From the beginning of the plant 1.5 meters from the edge of the pool planted in rows, the direction of planting pods should be arranged in an alternating manner. One plant heading south, one plant head north, and the gibbons around Dianchi Lake will all face the pool, which is conducive to the uniform distribution of the whip in the later period. The sowing depth is usually 12 cm to 15 cm. There are two types of methods: water and dry seed. The water is first discharged to a depth of 3 cm to 5 cm. Afterwards, the seedlings are sloping down and buried in the mud. Slightly dew. Drought is a shallow 12cm to 15cm deep shallow pit first, after which the species will be buried in the pit to bury, so as not to boring tip is appropriate. At the same time, the site of the joint should be slightly higher, so that the seed rake can be tilted to 25-30. Regardless of the method, it is necessary to irrigate after sowing and maintain a shallow water layer of 8 cm to 10 cm in order to increase the temperature and promote bud germination. 5, field management (1) Water level adjustment: In principle, the principle of “two lows and one high†is to be controlled, that is, low in the initial period, high in the middle period, and low in the later period. The initial water level should be maintained between 8 cm and 10 cm. After the beginning of summer, the temperature will increase and the amount of evaporation will increase. The water level should be maintained at 20 cm. Summer is the rapid growth period of lotus root, the water level should maintain 40 cm -50 cm. After the autumnal equinox, the shoot grows slowly, the photosynthetic product accumulates in the underground stems, and it enters the starch growth stage. The shallow water level should be maintained at 5 cm to 8 cm. (2) Scientific fertilizer: According to the law of growth and development of lotus root, two key fertilizers should be applied. For the first time, 30 days to 40 days after sowing, that is, when the 2nd to 3rd leaves are produced, 40kg of Sanyuan Compound Fertilizer per 667m2 or 75kg to 100kg of Dung are used for the second time. Before and after the leaf was unfolded one week before, at this time, some lotuses had been opened. At the early stage of reclamation, 15 to 25 kg of urea and 5-10 yuan of ternary compound fertilizer were applied every 667 square meters. Into the pool. Before each topdressing, shallow pool water should be placed, and the water level should be restored after 4 to 5 days. (3) Plant adjustment: The floating leaves were removed and the floating leaves gradually became yellow and dry after being planted for about 1 month. The water should be removed and the water temperature should be increased. Twisting peduncles, when the buds occur, the peduncle will be musli, 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 side, the hoe should be pulled out to the field in time, and the growth peak should be turned every 2 days to 3 days, and stagnated 1 week before the harvest. 6. Pest control Phlegm can be used 50% carbendazim WP 500 times plus 75% chlorothalonil wettable powder 500 times spray control, can also be used 1:1 mixture of the above two drugs, 500 grams per 667 square meters plus soil 25 kg -30 Kilograms, stuffy stuffy 3 hours - 4 hours, thrown into the shallow water layer. Aphids can be treated with 40% Dimethoate EC 1000-1500 times. package; blister; plastic blister; plastic tray taicang hexiang packaging material co.,ltd , https://www.medpackhexiang.com
