Planting method for increasing pear jujube fruit setting rate

Abstract

The invention discloses a planting method for increasing the pear jujube fruit setting rate. The method is characterized by comprising the following steps of 1 fertilization, wherein from the end of October to the beginning of November, organic fertilizer is applied to pear jujube trees, a mixed bactericide is sprayed to a fertilization pit, and in spring, organic fertilizer and multi-element compound fertilizer are applied in a supplementary mode; 2 pruning treatment, wherein in winter, jujube tree deadwood and excessive branches are sheared off, from March to April, main stem branch terminalbuds are removed, long bearing branches and high-density branches are sheared off, and new shoots are treated; 3 interplanting, wherein cape jasmine is planted in the empty space among jujube trees;4 florescence, wherein from the first half of the month of pre-blooming of jujube trees, a flower protecting treating solution and a plant extracting solution are used for being sprayed, and beehivesare arranged in each mu of the planting region; 5 fruit bearing period, wherein after fruit bearing of jujube trees, a plastic film is used for covering the upper portions of the jujube trees, tyrosine, bamboo fiber powder and glycerinum are added into the flower protecting treating solution, and the bactericide extracting solution is used for being sprayed.

Description

Problems solved by technology

[0003] The present invention aims at the existing problems: pear jujube belongs to multi-flowered tree species with many flowers, but the natural fruit setting rate is only 0.6%-1.2%, which seriously affects the economic benefits of pear jujube; pear jujube has strong growth ability, vegetative growth and reproduction Growth coincides, vegetative growth digests a large amount of fertility, which cannot meet the fertility required for reproductive growth; pear jujube flowers are small, the amount of pollen is small, artificial pollination cannot be carried out, and the flower fragrance is weak, it is difficult to attract pollinating insects, resulting in low pollination rate; Affected by temperature and rain, pear jujubes are prone to cracking and fruit drop, and the maturity of pear jujube fruits is not uniform, resulting in poor economic returns
