Auxiliary agent capable of increasing pear fruiting rate

Abstract

The invention belongs to the technical field of agricultural cultivation and particularly relates to an auxiliary agent capable of increasing a pear fruiting rate. The auxiliary agent is prepared from, by weight, 500 parts of deionized water, 3-4 parts of methionine nickel chelate, 1-2 parts of boric acid and 1-2 parts of sugarcane leaf polysaccharide. The auxiliary agent is mixed with pollen in accordance with a weight ratio of 2:27, and a pollinator is used for pollinating pear flowers at 14-15 o'clock from April to May. Compared with the prior art, the auxiliary agent capable of increasing the pear fruiting rate has the advantages that when the auxiliary agent is utilized during pear pollination, both the pear fruiting rate and the pear pollination rate can be increased, the weight of single fruit is increased by about 40% as compared with natural pollination, the high pear fruit quality can be kept, the pear commercial quality is improved and remarkable economical benefit is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to an auxiliary agent for improving the fruit setting rate of pear trees. Background technique [0002] Pear trees are cross-pollinated fruit trees, and the fruit-setting rate is very low if there is no flower pollination of different varieties. The flowering periods of varieties meet or overlap for a short period of time, or the tree ages of the main planting varieties and the pollinated varieties are different, or the flowering period is cloudy and rainy, which affects the normal pollination. In these situations, if artificial pollination can be carried out, the fruit setting rate can be greatly improved , under unfavorable conditions, to obtain a better yield, artificial pollination operation is cumbersome, labor-intensive, time-consuming and labor-intensive. In this case, pollinators are usually used to pollinate pear flowers. Although the work efficien...

[0002] Pear trees are cross-pollinated fruit trees, and the fruit-setting rate is very low if there is no flower pollination of different varieties. The flowering periods of varieties meet or overlap for a short period of time, or the tree ages of the main planting varieties and the pollinated varieties are different, or the flowering period is cloudy and rainy, which affects the normal pollination. In these situations, if artificial pollination can be carried out, the fruit setting rate can be greatly improved , under unfavorable conditions, to obtain a better yield, artificial pollination operation is cumbersome, labor-intensive, time-consuming and labor-intensive. In this case, pollinators are usually used to pollinate pear flowers. Although the work efficiency is improved, the pollination rate and the later stage However, the fruit setting rate has been seriously affected. In order to improve this situation, research on improving the fruit setting rate under the condition of using pollinators for pollination
