A kind of cultivation method for fast high yield and stable yield of drupe fruit trees

Abstract

The invention relates to a quick high-yield stable-yield cultivation method for stone fruit trees. The method includes: intensively putting common annual fruit tree seedlings in a seedling culture zone for root-restriction secondary seedling culture, applying microbial nutritional fertilizer, promoting growth prior to controlling, and culturing robust large seedlings with flowers and developed fibrous roots; then planting in field. The seedlings can enter a high-yield period in the second year after planting, and the seedlings are developed in root system and more in fibrous roots; since underground growth and aboveground growth of tree bodies are corresponding, the more the fibrous roots are, the more the middle branches are, the more the bearing branches are, the more fruits are borne, and the higher the percent rate of high quality fruit is; centralized seedling culture is performed in the first year, the planted fruit trees enter the fruiting period quickly, and land resources can be saved; the seedlings are shaped intensively before planting, so that the seedlings not good in tree shape can be eliminated, and orchard uniformity and yield are further improved; the seedlings are subjected to root-restriction planting during secondary seedling culture, so that the seedlings are promoted to grow fully and are high in stress resistance, disease resistance and drought resistance, and long-term high yield, high quality and stable yield of orchards are benefitted greatly.

Description

technical field [0001] The invention relates to a method for cultivating stone fruit trees, which is particularly suitable for the rapid, high and stable cultivation of stone fruit trees including peaches, apricots, plums, cherries, and prunes, and belongs to the technical field of fruit tree cultivation. Background technique [0002] Drupe refers to a type of fruit, which is a single fruit, a fleshy fruit developed from a carpel; generally, the endocarp is lignified to form a nucleus. Drupe fruit trees include peaches, apricots, plums, cherries, prunes, etc., and are one of the main fruit trees planted in my country. Peaches, apricots, and plums have been cultivated in my country for 3,000 years, but it usually takes 4 years for peaches, 5 years for apricots and plums, and more than 6 years for large cherries to enter the high-yield period. The original early high-yielding method used "carving, peeling, pulling" and hormones to force the young trees to flower early, but it...

Problems solved by technology

Peaches, apricots, and plums have been cultivated in my country for 3,000 years, but generally it takes 4 years for peaches, 5 years for apricots and plums, and more than 6 years for large cherries to enter the high-yield period.

The original early high-yield method uses "carving, peeling, pulling" and hormones to force the young trees to flower early, but it will cause the tree to weaken, and the quality of the formed flower buds is poor, the fruit quality is poor, the life of the tree is shortened, and a lot of manpower and material resources are consumed.

In foreign countries, a large number of large seedlings that have been shaped in the nursery have been used for colonization and early fruiting. However, the domestic nursery stock market still lacks the supply of large seedlings with branches, which are all annual or biennial seedlings without branches.
