Problems solved by technology

[0003] For a long time, people have realized the role and significance of pruning in preventing chestnut fruiting parts from moving outwards and the phenomenon of baldness inside the crown. There are not many studies on making the canopy achieve good ventilation and light transmission conditions, balancing the nutrition of the tree body, providing better material accumulation for plant growth, and increasing the yield of chestnuts

Abstract

The invention discloses a pruning method for a chestnut tree. The pruning method includes the steps of (1) whole pruning: setting four levels from top to bottom on the whole chestnut tree, wherein the numbers of mother branches retained in the area of canopy projection per square meter are 8, 13, 16 and 22 respectively, and the branch length range of retained fruit branches is 25-30 cm; after pruning, immediately applying a liquid fertilizer; (2) sprouting period pruning: removing the buds of the middle and lower parts of main branches, retaining two big buds on the main branches, and retaining only one big bud on each flourishing branch of lateral braches; (3) flowering phase pruning: when mixed inflorescences at the top of a shoot show the red, removing tips in front of fruit; when male flowers grow to less than 2 cm, removing other male flowers except four retained inflorescences at the top of the shoot, and making the ratio of the male inflorescences and the mixed inflorescences reach 1:7; (4)pest and disease damage area pruning. The pruning method for the chestnut tree can significantly increase the yield of chestnuts and provide a new research direction for planting chestnut trees.

Description

【Technical field】 [0001] The invention relates to the planting field of chestnut trees, in particular to a method for pruning chestnut trees. 【Background technique】 [0002] Chestnut is one of the main woody food tree species in my country. However, due to its biological characteristics such as light-loving, apical dominance, and strong branching power, it is easy to make the canopy closed, resulting in insufficient light and ventilation inside the canopy, resulting in the fruiting of the canopy. The phenomenon of outward migration reduces fruit yield and quality, resulting in economic losses. Pruning in winter can adjust the structure of the tree, improve the internal light of the canopy, and adjust the distribution of nutrients among various organs. There are differences in the ventilation and light transmission conditions in the canopy with different pruning intensities, resulting in differences in temperature, humidity and light. Differences in morphological structure an...
