If the base fertilizer is insufficient and the fertilizer supply is not available, the seedlings will grow more slowly in the early stage. In the early stage, the seedlings could not stand the shelf because of the lack of growth, and people would inevitably apply the stimulating nitrogen fertilizer in the middle of cultivating and cultivating. In this way, the seedlings will grow fiercely, and due to the rain, the humidity, the incompleteness of the sun, and the high temperature and humidity, a large number of panicles, sheath blight, bacterial blight and various pests will occur, resulting in reduced production. Therefore, in order to capture the yield of early-made rice, it is necessary to apply sufficient base fertilizer when transplanting rice. The specific method is: medium-sized can use 30 kg of super-calcium phosphate, 30 kg of ammonium carbonate, and appropriate amount of farmyard fertilizer, 60% to 70% of fertilizer should be used as base fertilizer, 30% to 40%. Topdressing and late fat. Before the transplanting, the base fertilizer is applied to the field, and the soil is fully mixed, so that the middle and lower layers of the soil are mixed with various fertilizers. The roots of the rice roots can absorb the fat points, so that the seedlings grow rapidly in the early stage, and the early growth is fast and the growth is strong. . Potash is applied in the medium term, making it strong and hard, and lodging resistance.
Early rice application of base fertilizer to increase production
Due to the low temperature in the early stage and the high temperature in the later stage, the rice must be applied to the base fertilizer in order to obtain high yield. Because of the low temperature in the early stage of early rice production, the effective nutrient decomposition of fertilizers and soils is slow, the rice grows in a low temperature climate in the early stage, and the roots have weak fertility, which makes the early growth slow.
