Autumn sowing phosphorus crops fertilize with fertilizer
Dry soils have strong ability to fix phosphorus Therefore, although it is not necessary to apply phosphorus to every crop during different rotations of crops, it is necessary to consider the application of phosphate fertilizers that can maximize the effect of phosphate fertilizer. Autumn crops are the best choice for phosphate fertilizers throughout the year. Mouthwash. Autumn crops are mostly dry crops Under dry conditions, the availability of phosphorus is low. After entering the winter, the activity of microorganisms in the soil is weak. The phosphorus capacity is small, the rate is slow, and the intensity is low. Moreover, under dry conditions, the soil water tension is large, the mass flow and diffusion of phosphates are reduced, and the phosphorus has a small displacement, and the effectiveness is lower than that of rice under water conditions. 3 times. In addition, some dry crops, such as wheat crops, originally belong to crops with poor response to phosphorus, while large and wheat crops require more phosphorus during the returning green period and the tillering stage. Therefore, the sowing date of wheat crops emphasizes phosphorus application to meet the demand of phosphorus for the critical period. Application method should pay attention Phosphate fertilizers should be mixed with various organic fertilizers or ammonium bicarbonate. During autumn sowing, they should be applied with acupuncture and applied as base fertilizer. The general dosage is about 20-25 kilograms per mu, and the application depth is 6-10 cm. Applying 3 to 5 kg of phosphate fertilizer and 1× dry fine soil to apply seed dressing, using basal fertilizer and seed fertilizer, combined with shallow application and deep application, can achieve good fertilization results.

From the point of view of improving the stress resistance of autumn crops, after the autumn sowed crop is sown, the crops are susceptible to drought and freezing under conditions of less severe winter rain and low temperature, and the application of phosphate fertilizer can improve autumn conditions. The hydrated and adhesive nature of the cell protoplasm during the wintering season of the sown crops will reduce the freezing point, thus improving the cold resistance and drought resistance of the crops, and will help the winter sowing of crops safely in winter. In addition, the application of phosphate fertilizer for autumn sowing of winter green manure is not only the legume green manure itself is hi phosphorus crop, the application of phosphate fertilizer to strengthen the photosynthesis of plants, produce more carbohydrates, promote lush foliage, more accumulated material, but also Supply rhizobial growth and reproduction, enhance its nitrogen fixation.
