Walnut tree cultivating method

Abstract

The invention relates to a walnut tree cultivating method. The method comprises the specific steps that soil preparation is carried out, wherein wide rows and narrow rows are arranged at intervals, the width of the wide rows is 105-130 cm, the width of the narrow rows is 29-33 cm, and water delivery pipes are laid in the middles of the narrow rows; improved varieties and strong seedlings are selected, wherein improved varieties and strong seedlings of large Juglans sigillata or fine and fragrant Juglans sigillata are selected, wherein the height is larger than 0.35 m, the branch diameter is larger than 0.015 m, the main root preservation length is larger than 0.155 m, and the number of side roots is larger than 16; planting is carried out; fertilization and water delivery are carried out; field management is carried out, wherein soil water content is kept 60-85% of the maximum field capacity through the water delivery pipes, and fertilizer is delivered when water is delivered; trees are pruned; pest and disease prevention and control are carried out. By the adopting the planting mode that one narrow row is arranged between every two adjacent wide rows, border row advantages of plants are artificially made, the light transmittance of walnuts is increased, photosynthetic efficiency is improved, topdressing, water delivery and harvesting of the walnut plants are facilitated, nutrient balance application and walnut absorption are facilitated, pressure of wind to the plants is weakened, and the walnut output is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, in particular to a method for cultivating walnut trees. Background technique [0002] Walnut is an important oil-bearing fruit, which generally contains 60% to 75% oil and more than 15% protein, and also contains calcium, phosphorus, iron, vitamins and other nutrients. Phlegm, wind tonifying blood, warming intestines and tonifying kidney are important Chinese herbal medicines with high economic value. Vigorously developing walnut production is of great significance and great prospects for greening and beautifying barren hills, increasing oil plant raw materials and medicinal materials, and increasing farmers' income. The ideal economic forest tree. [0003] The traditional walnut cultivation is a single plant in one hole, with equal row spacing. This planting method has poor plant permeability, and the root growth, lodging resistance, surface water evaporation rate and night temperatur...

Problems solved by technology

[0003] The traditional walnut cultivation is a single plant in one hole, with equal row spacing. This planting method has poor plant permeability, and the root growth, lodging resistance, surface water evaporation rate and night temperature distribution of the crops are not conducive to the growth of walnuts, resulting in This planting method has disadvantages such as low yield and poor product quality, and is not conducive to field management and harvesting.
