Abstract

The invention discloses a high-quality and high-yield fertilization technology for winter jujube tree cultivation, relates to the technical field of crop planting, and solves the problems of lack of trace elements in soil, reduction of soil quality and aggravation of plant diseases and insect pests in an existing winter jujube planting technology. The technology comprises the following steps of (1) heavily and deeply applying base fertilizer: from the middle ten days of September to the end of October in autumn every year, digging a fertilization ditch with the depth of 20-30 cm in a crown drip boundary, and applying 200-400 kg of balanced biological organic-inorganic compound fertilizer per mu; (2) lightly and shallowly applying germination fertilizer: 7-10 days before germination of winter jujubes in spring every year, digging a shallow ditch or flushing water to apply 40-60 kg of high-nitrogen polyglutamic acid compound fertilizer per mu; (3) dressing 60-100 kg of high-potassium biological organic-inorganic compound fertilizer and 20-40 kg of high-nitrogen polyglutamic acid compound fertilizer in a fruit expansion period; and (4) spraying calcium fertilizer containing amino acidtrace elements to the leaf surfaces for 3-5 times after fruit setting. According to the technology, the problems in continuous improvement of multi-year planting quality of the winter jujubes and products are better solved.

Description

technical field [0001] The invention relates to the technical field of crop planting, and more specifically relates to a high-quality and high-yield fertilization technology for cultivating winter jujube trees. Background technique [0002] Winter jujube is a variety of jujube tree, and it is also recognized as a variety with good economic benefits. It is rich in carbohydrates and vitamins. It is fresh and delicious, with crisp skin and excellent quality of tender meat. It is a high-grade deciduous fruit tree in the north; it can crack when it falls on the ground when it is mature; it is juicy and has no residue, sweet and fragrant; the flesh is thick and the core is small, and the edible rate reaches 96.1%. However, in recent years, due to the level of fertilization management and other reasons, the yield, quality and stress resistance of winter jujube in many areas have declined significantly. [0003] The normal growth and development of winter jujube trees and the forma...
