Problems solved by technology

[0003] In recent years, with the intensification of global climate warming, summer rainfall in southern Jiangsu (Meiyu) and extreme high temperature (>35°C) have increased in frequency and duration, and the soil moisture content in Meiyu season is too high Causes waterlogging, cannot supply oxygen to the root system normally, directly affects its respiration and normal physiological activities, and causes a large number of root systems to age and suffocate to death

Abstract

The invention discloses a solid fertilizer for preventing aging and foot rot of pear root systems and a preparation method thereof. The fertilizer is prepared from water-absorbent resin, hydroxy propyl distarch phosphate, cellulose, cross-linking agent, bentonite, urea, ammonium dihydrogen phosphate, ammonium bicarbonate, potassium chloride, humic acid, amino acid chelated copper, oligosaccharinsand Tween-20. The solid fertilizer is adopted to treat a sand pear plantation, the effect of overcoming high temperature and rainy barriers is achieved, soluble solid content of obtained fruit is improved by 10%, and the commodity fruit rate is improved by 30%.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a solid fertilizer for preventing pear tree root system aging and root rot and a preparation method thereof. Background technique [0002] Sand pear, native to the Yangtze River Basin and its south area, is widely cultivated in the southern part of Jiangsu Province. It is mainly cultivated with early-maturing varieties such as "Aiganshui", "Cuiguan" and "Xingshui". The maturity period is mainly concentrated in the July and August. Pears are suitable for cultivation in sandy loam soil with deep soil layer, good drainage, and relatively high fertility level. The optimum water content for root growth is 60%-80% of the maximum field water holding capacity of the soil. [0003] In recent years, with the intensification of global climate warming, summer rainfall in southern Jiangsu (Meiyu) and extreme high temperature (>35°C) have increased in frequency ...
