The occurrence of rice rotten pods in the early spring is relatively common. Prevention methods are as follows: Select seed selection. Seeds of high purity and cleanliness, do a good job of drying seeds before soaking, and increase the germination rate and vitality of seeds. Good and good Putian: Putian should choose to shelter from the sun, high ground, convenient drainage and irrigation, medium-fertilizer field, site preparation for a fine bed surface, deep ditch, drainage and irrigation unimpeded. Thin film breeding. It is best to use arch-type perforated membranes to raise oysters, which can effectively solve the problem of low temperature causing rot. Improve soaking and germination techniques. When soaking germination, the temperature must be properly grasped. Requirements to achieve 36-38 °C, exposed whitehead, suitable temperature 30-35 °C steady germination, cooling 20-25 °C thin spread good buds, so that buds to achieve homogeneous, uniform and strong. Improve the quality of sowing. According to the characteristics of the species, the sowing date, seeding rate and seedling age should be determined. Depots should be used to select seedlings, and it is recommended to plant seedlings with half-grained grains. Strengthen fertilizer and water management in Putian. Until the emergence of buds, ventilation and oxygen supply are mainly used. Putian simmering surface is kept moist to facilitate long rooting and rooting. In the 2 leaves and 3 leaf stages, heat preservation and anti-freeze are the main methods, and shallow water can be used for irrigation to prevent dead seedlings. After 3 leaves can be nursed in water. 7-10 days after sowing, five preventions must be done to prevent low temperature, prevent rainwater, prevent high temperature from burning seedlings, prevent floodlights from drying out, and prevent water from seepage. Covered half ditch water. After the rain drained water. Appropriate fertilization, basal fertilizer with a combination of decomposed human urine and phosphate fertilizer is appropriate. Top dressing should be applied in different times. After the seedlings are applied, “breaking rooting fertilizer†should be applied, and “weaning fertilizer†applied at the 5 leaf stage should promote hair roots and hair leaves. Chemical control. Seedling Blight: When the raft is made, dilute 1000 times with 70% Dixon per acre and spray to ensure that no blight occurs in the 3-leaf stage. 10000Hz High Frequency LiDAR Module 10000 Hz is one of our 2021 new solutions products,which can be widely used in drone postioning, car anti-collision, intelligent traffic monitoring etc. with high accuracy.
