Improving method for fruit setting rate of almond trees

Abstract

The invention provides an improving method for the fruit setting rate of almond trees. The improving method comprises the following steps: firstly, selecting varieties: selecting the almond trees with freeze resistance and air temperature fluctuation resistance as main cultivars, and selecting the almond trees with the same flowering stage as pollinating varieties, wherein during planting, the quantity proportion of the main cultivars to the pollinating varieties is 3:1; secondly, managing fertilizer and water; applying base fertilizer in autumn, dressing before germinating, and spraying foliage fertilizer at the swelling stage of fruits; irrigating tree bodies at the flowering stage, after flowering, in drought seasons and after fertilizing; thirdly, performing artificial supplementary pollination: dissolving white sugar, urea, borax and pollen in water and uniformly stirring to obtain pollen liquid, feeding the pollen liquid in a sprayer and then spraying the pollen liquid to almond tree flowers; fourthly, spraying a plant growth regulator: before flowering, spraying a mixture of plant mineral elements and the urea to the tree bodies, spraying a mixture of maleic hydrazide, the plant mineral elements and the urea at the full-bloom stage, and spraying a mixture of the plant mineral elements, the urea and monopotassium phosphate after flowering; fifthly, resisting cold. According to the improving method provided by the invention, the fruit setting rate and the yield of the almond trees can be effectively improved.

Description

Technical field: [0001] The invention relates to a method for improving the fruit setting rate of apricot trees. Background technique: [0002] Apricot tree, deciduous tree; terrestrial, glabrous plant; leaves alternate, broadly ovate or round ovate leaves with obtuse serrations; near the top of the petiole with two glands; light red flowers solitary or 2-3 at the same time Raw, white or reddish; the drupe is round, oblong or oblate, the peel is mostly white, yellow to yellow-red, and the sun part often has red halos and spots; the flesh is dark yellow, sweet and juicy; the nuclear surface is smooth without spots Pores, thick and grooved core margins; bitter or sweet kernels; flowering period March-April, fruit period June-July. Apricot trees germinate and bloom earlier than other drupe fruit trees, with a shorter flowering period and low pollination rate. They are easily affected by low temperature and frost in early spring, resulting in a very low fruit setting rate and a...

AI Technical Summary

Problems solved by technology

Apricot trees germinate and bloom earlier than other drupe fruit trees, with a shorter flowering period and low pollination rate. They are easily affected by low temperature and frost in early spring, resulting in a very low fruit setting rate, which affects the yield of apricot trees.
