Problems solved by technology

In addition, the reason for the emergence of stiff buds is mainly related to the high-temperature and high-humidity climate in June, July, and August of the previous year. This period coincides with the critical period of flower bud differentiation of fruit trees. Vigorous growth, new shoots stop growing late, resulting in unbalanced vegetative growth and reproductive growth, lack of trace elements, resulting in poor differentiation of flower buds. Generally, fruit tree buds are soft, bursting and browning in August, resulting in flower buds in the second spring. Unable to germinate and form stiff buds, causing serious losses to production

Abstract

The invention belongs to the technical field of pesticide preparations, and particularly relates to an insecticide for preventing and controlling wizened buds of fruit trees, as well as a preparation method and a using method thereof. The insecticide is prepared from the following components in parts by weight: 20-30 parts of paclobutrazol, 10-16 parts of ribosylzeatin or cytokinin or kinetin, 20-30 parts of phosphorus, 30-40 parts of potassium, 25-35 parts of calcium, 7-13 parts of magnesium, 7-13 parts of manganese and 7-13 parts of zinc. The using method comprises the following steps: applying the insecticide 2-3 times every 10-15 days during the flower bud differentiation period from early June to late July to control nutrition and growth of fruit trees, supply trace elements (potassium, calcium, magnesium, manganese, zinc and the like) essential to flower bud differentiation of fruit trees and promote complete flower bud differentiation and excellent development. The insecticide remarkably achieves the effect of preventing and reducing occurrence of wizened buds of fruit trees, and ensures normal yield and benefit of fruit trees.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to a medicament for preventing and treating stiff buds of fruit trees, a preparation method and a use method thereof. Background technique [0002] Fruit trees such as pears and peaches will experience different degrees of dead buds during production and cultivation in many years, that is, after the flower buds of pears, peaches, apples and other fruit trees germinate in spring, some flower bud growth points will die or cannot open normally, and will soon form a detachment layer and fall off. This kind of flower bud is called stiff bud, and this phenomenon is the stiff bud phenomenon of fruit trees, especially with some varieties of pear tree stiff bud phenomenon is serious. [0003] Stiff buds of fruit trees mainly cause the death of flower buds, which not only affects the yield of the year, but also forms a bare zone, causing the fruiting parts to move o...
