茶树是多年生植物。施用大量的无机肥料是栽培它的特点。我们在自己的试验中曾力求研究过长期施用磷肥对土壤和植物发生的影响。我们的试验是在全苏茶叶及亚热带作物研究所农业化学部,1933年就选好的茶园上进行的,这块茶园是1929年建立于灰化红壤上的。每丛营养面积是1平方米,重复4次。氮肥以硫酸铵的
Tea tree is a perennial. Applying a large amount of inorganic fertilizer is characteristic of cultivating it. In our own experiments we have sought to study the effects of long-term application of P fertilizers on soils and plants. Our experiments were conducted at the All-Su Tea and Subtropical Crop Research Institute’s Department of Agricultural Chemistry, which was commissioned in 1933 on the tea plantation that was established in ashes in 1929. Each plexus nutrient area is 1 square meter, repeated 4 times. Nitrogen fertilizer with ammonium sulfate
