试验于1980年开始,1984年验收,试验区面积528.5亩,平均亩产2093公斤,达到国内先进水平。主要措施:1.整地改土:对沙地果园压土,每亩压80～100车湾泥或粘土;麦收后,每亩压麦糠和杂草300～400公斤。2.合理施肥灌水,基肥以土杂肥和磷肥为主,采收后立即进行;追肥在花前、花后、8月初分别采用“重、轻、重”的原则进行,
The test started in 1980 and was accepted in 1984 with an area of 528.5 mu and an average yield of 2,093 kg per mu, reaching the advanced domestic level. Main measures: 1. Soil preparation and soil improvement: For sandy soil in the orchard, the pressure is 80-100 car mu or clay per acre; after harvest, 300-400 kilograms of wheat bran and weeds are pressed per acre. 2.
