How can Iita Ikeda cultivate high yield?

First, the sowing time from the climate, should be before and after the frost break, the temperature is stable at 15 °C, 5 cm ground temperature stable through 12 °C.
Second, the selection of species selection of disease resistance, high yield, strong resistance, wide adaptability, good product traits, species should be selected in line with the characteristics of this species, with more than 2 nodes of the child or mother of the complete lychee The body is thick, tidy and intact, and the buds are complete and robust. Mu required 300-350 kg.
Third, the planting density of early maturing varieties can be slightly dense, medium and late-maturing varieties should be thin, large varieties of pods, buds and more should be thin, and vice versa. Generally used about 200 centimeters away, the distance between 70-100 centimeters. 300-500 holes per acre. Generally 2 plants per hole, 3 plants can be planted. A large, large bud can be used with a depth of 15 cm.
IV. Management of Pool Pools
1. In principle, the management of the water layer shall be "light-deep-light". After the next species, in order to improve the ground temperature during the day, keep 3-5 cm of shallow water, but when encountering cold currents and low night temperatures, deep water should be poured around 10 cm to keep the ground warm. Generally, two times of water is added in one season. When there is high storm water level, drainage holes can be used to adjust the water level. When the temperature is higher, the water can be deepened to 15-20 centimeters to prevent high temperature damage. After the beginning of autumn, enter the waterlogging period, the water level is kept 5 centimeters, especially in the early stage of the scab, and the paddy field can be kept dry so that the ground temperature can be increased by “digging and promoting”.
2. Top-dressing seedlings: After the leaves emerged from the water, 12 kg of urea was applied. Relieve fertilizer: After the third leaves are exposed on the water surface, apply 12 kg of urea per mu, 12 kg of potassium sulfate; when the front leaves of the summer heat is yellow or edge curling or when the lotus is not bright, apply 12 kg of urea per mu, potassium sulfate 12 Kilograms cannot be fertilized after the great heat.
3. Turn your head and turn your head and call it your whip. The adjustment of the whip is carried out from the end of June to the end of July, once every 7 days, for a total of about 4 times. For the first two times, the new leaves of lantana plant were less than 60 cm away from the field. In the latter two times, the new leaves of Tadpoles were less than 40 cm away from the field and they would be adjusted. The adjustment time should be chosen from 9:00 am in sunny days to no sunlight in the afternoon.
4, pick the old leaves, folded stalks When the leaves are full, the floating leaves gradually wither, should be promptly removed in order to allow Tianshui as much as possible to accept the irradiation of sunlight to improve ground temperature and improve ventilation conditions. When some of the leaves are yellowed or withered due to pests or other reasons, they should also be removed. Lotus lotus is for the purpose of picking, if there are buds should be bent pedicel in order to avoid flowering consume nutrients. After the end of lotus root production, about 15 days before harvesting, the irrigation cuts off the petiole of the lotus leaf on the floor, stops the underground part from breathing, and increases the commercial value of lotus root.
