Legume crops such as broad beans, peas, etc., cruciferous crops such as rapeseed, radish, etc., sensitive to phosphate fertilizer, large demand, increased application of phosphate fertilizer during autumn sowing, can meet the demand in the critical period of phosphorus demand, seedling stage, promote Its early maturity, quality and high yield are very beneficial. The roots of the phosphorus-producing crops are developed, and the utilization rate of phosphate fertilizer applied in the current season is increased by about 10% compared with other crops. Autumn crops are mostly dry crops Under dry farming conditions, the effectiveness of phosphorus is low. After entering winter, the soil has weak microbial activity, small phosphorus capacity, slow rate, low strength, large soil moisture tension, and reduced phosphate flow and diffusion. Phosphorus has a small displacement and is 2 to 3 times less effective than phosphorus in rice under water conditions. In addition, some dry crops such as wheat crops are originally poor crops that respond to phosphorus, while barley and wheat require more phosphorus during the greening and tillering stages. Therefore, the sowing season of wheat crops emphasizes phosphorus application to meet the demand for phosphorus in the critical period. Strong ability to fix phosphorus in dry soil From the point of view of improving the resistance of autumn-sown crops, after the sowing of autumn-sown crops, under the harsh conditions of harsh winter rain and low temperature, the crops are susceptible to drought and freezing, and the application of phosphate fertilizer can improve autumn. The hydration and adhesion of the cell protoplasts during the wintering period of the crops will reduce the freezing point, thereby improving the cold tolerance and drought tolerance of the crops, which is conducive to the safe wintering of autumn-sown crops in winter. In addition, the winter green fertilizer for autumn planting emphasizes the application of phosphate fertilizer. Not only the legume green manure itself is a phosphorus-producing crop, but also the application of phosphate fertilizer to enhance the photosynthesis of plants, produce more carbohydrates, promote the luxuriance of stems and leaves, accumulate more substances, and It supplies the growth and reproduction of Rhizobium and enhances its nitrogen fixation. Therefore, in different rotation systems, although it is not necessary to apply phosphorus to each season crop, it must be considered to be applied to the cornice that can maximize the effect of phosphate fertilizer, and the autumn sowing crop is the best priority for applying phosphate fertilizer throughout the year. Rinse mouth. Phosphate fertilizer application method Phosphate fertilizer should be mixed with various organic fertilizers or ammonium bicarbonate. In the autumn sowing, the application of acupoints and strips should be applied as the base fertilizer. The general dosage is 20-25 kg per mu, and the application depth is 6-10 cm. 3 to 5 kg of phosphate fertilizer plus 1 times of dry fine soil mixed seed application, using the combination of base fertilizer and seed fertilizer, shallow application and deep application.
