钾素是果树主要营养元素之一,对植物的光合作用和碳水化合物的合成有重要作用,并能促进淀粉和糖的运转、积累,对氮素的代谢也有密切的关系。我们于1976年开始在全省各地进行钾肥施用量的研究,探讨苹果树施用钾肥数量的指标和提高果品质量的作用。试验地点在辽南、辽西共11处。一、试验方法试材为国光、金冠、红星品种,树龄10～20年生左右。以单株为小区,重复5～10次,
Potassium is one of the main nutrient elements of fruit trees and plays an important role in the photosynthesis and carbohydrate synthesis of plants and can promote the operation and accumulation of starch and sugar, and also has a close relationship with nitrogen metabolism. We began in 1976 throughout the province to study the amount of potash application, to explore the apple tree index of the amount of potassium and improve the quality of fruit. Test sites in southern Liaoning, Liaoning, a total of 11. First, the test method Guoguang, Golden Delicious, Red Star varieties, age 10 to 20 years old or so. To plant for the community, repeat 5 to 10 times,
