Rice seedlings and dry seedlings have been widely promoted, but due to various reasons, yellow seedlings, dead seedlings, dead seedlings and dead shoots often appear in the spring. In order to prevent these phenomena from occurring, it is one of the key measures to do a good job of fertilizing paddy rice seedlings. The winter seedbed fertilization techniques are briefly described below. 1. Seedling selection Rice seedlings grow best in neutral to acidic soils, and dry nursery seedling beds should be chosen to avoid saline and alkaline soils and easy-to-grain soils; rice should be warm and happy, and dry seedlings should be avoided under tree shade or tall buildings. The shade and so on. Generally selected are soils with high organic matter content, low salinity and alkali, loose and breathable water, low groundwater level, leeward sunlight, close to water sources in the wetland and vegetable garden fields. 2. Remaining seedbeds Rice seedlings in recent years Due to large seeding rate and high seedling density, rice seedlings, tall seedlings, thin seedlings, stiff seedlings and dead seedlings often appear. These high-density seedlings are transplanted into the field, and they grow slowly, send trees late, have fewer tillers, and are not susceptible to disease, causing diseases such as panicles, fewer spikelets, and late ripening. Especially for conventional japonica rice, the phenomenon of seedling squeezing often occurs due to lack of seedbeds. Therefore, the seedbed should be kept to lay the foundation for the cultivation of multiple seedlings. According to the practice of many years and many experiments, the ratio of general hybrid rice seedlings to fields is preferably 1:12 to 15, the hybrid japonica rice is preferably 1:10 to 12, and the conventional rice is 1:8 to 10. 3. Winter fertilization Rice dry nursery seedlings fertilization, should be applied organic fertilizer, broken grass, soil miscellaneous fertilizer and phosphorus and potassium fertilizers, conditions can be applied to humic acid high efficiency liquid fertilizer, etc., generally per acre seedbed miscellaneous fertilizer 1000 Kilograms, 500 kg of comminuted grass, 30 to 40 kg of phosphorus and potassium fertilizers, applied in 2 to 3 times. Rotate the tiller or turn it once after each fertilization to fully mix the fertilizer and the soil. In addition, raw organic fertilizers should be applied early and not too late; it is forbidden to use alkaline fertilizers such as grass ash, human urine and manure. 4. Interplanting Fertilizers Before autumn and fall, planting parsley, cabbage, spinach, and green vegetables on the dry nursery bed of rice can improve the soil and reduce the salinity of the soil, and it can also obtain better economic benefits. Conditions can also be grown greenhouse celery, zucchini, cucumbers, tomatoes, etc., while using the ground to fertilize the seedbed to obtain higher economic income. As long as reasonable arrangements are made, rice seedlings will not be delayed. In addition, rapeseed and forage grasses used for livestock consumption on rice seedling beds are better for fertilization, and the soil can reach sandy loam soil standards with a granule structure. The rice will be harvested before the rice falls in the second year and fertilized properly. The quality of dry seedlings cultivated is higher.
