Fertilizing method for apricot trees

Abstract

The invention discloses a fertilizing method for apricot trees. The fertilizing method comprises the following steps: (1) measuring soil nutrients, namely, arranging a plurality of sampling points under a plurality of fruit trees in an orchard, taking soil samples at depths of 0-20cm and 20-80cm from any sampling point, mixing the soil samples at the same sampling layer of the same fruit tree, airing, measuring organic matters, total nitrogen, rapidly available nitrogen, available phosphorus, rapidly available potassium, exchange calcium, exchange magnesium, available sulfur, zinc, iron, manganese, copper and boron in the sample, and carrying out statistic analysis on dependency of data of the soil samples at the two layers; and (2) according to the statistic analysis result on dependency of data of the soil samples at the two layers, by taking nutrients having significant differences as base fertilizers, applying the fertilizers with alternative deep placement and shallow placement every other year, dividing nutrients without significant differences as base fertilizers and additional fertilizers, and fertilizing by adopting a manner of combining deep placement of the base fertilizers and shallow placement of the additional fertilizers. According to the fertilizing method provided by the invention, by considering movement abilities of different nutrients, the time and spatial distances from application of the nutrients to nutrient absorption of roots are shortened, the benefits are obvious, and the operation is simple.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular, the invention relates to a method for fertilizing apricot trees. Background technique [0002] As a characteristic forest and fruit industry in Xinjiang, apricot accounts for an important part of farmers' income and is an important part of Xinjiang's characteristic economic development. Apricot fruit is rich in nutrition, contains a variety of organic components and vitamins and inorganic salts necessary for the human body. It is a fruit with high nutritional value. Almonds are more nutritious, containing 23-27% of protein and 50-60% of crude fat. , sugar 10%, also contains phosphorus, iron, potassium and other inorganic salts. During the growth of crops, they need to absorb a large amount of nutrients from the soil. If the required nutrients are not met, there will be an imbalance between the consumption and accumulation of nutrients in the tree body, which will no...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of fertilization method of apricot tree, this method is aimed at the problems such as fruit tree growth is slow, quality is not good, yield is low, management is extensive, adopts effective fertilization method and mode, improves fertilizer utilization rate, shortens nutrient transportation. Time-shifting, promoting the absorption of fruit trees, the effect is obvious, breaking the situation of high input, low utilization, and low output, and promoting high-quality and high-yield fruit trees
