Method of chemically erasing flower buds of citrus saplings

Abstract

The invention provides a method for chemically erasing the flower buds of citrus saplings. When the citrus saplings germinate and grow until the flower buds are just visible in spring, the flower buds are sprayed with prohexadione calcium + fomesafen, and the flower buds are sprayed to a moist state to induce The flower buds wither and fall off, prevent the loss of tree nutrients caused by flowering and fruiting, promote young trees to accelerate the growth of new shoots and crown expansion, and enter the high-yield period early. After the flower buds are chemically erased by the method of the invention, the saplings do not bloom or bear fruit, the nutrient consumption is reduced, the canopy of the tree expands rapidly, and the effect of saving labor is very prominent. The method of the invention is simple and easy to implement, has low cost and is beneficial to popularization in the production process.

Description

Technical field [0001] The present invention relates to the field of fruit trees cultivation, and in particular, a method of chemically erasing citrus sexy buds. Background technique [0002] Citrus is the largest fruit tree in my country. In 2018, the national citrus area has been as high as 40 million mu, and the cultivated citrus is a grafting seedlings, namely: the underground partial rootstock variety and the upper part of the grounding population grafting . Typically, rootstocks and spikes are varieties in two genetic backgrounds. The rootstock is grown by seed seeds, and the scocket is the branches of the healthy adulthood quality citrus tree. [0003] Since the citrus seedling variety is collected from adult citrus trees, the spike is physiologically mature, and the physiological age of the citrus married seedling seedling is also mature. Therefore, production of citrus seeds cultivated, in the seedling period (small tree or 1-2 years old tree, the following is known as t...

Problems solved by technology

Therefore, the citrus seedlings cultivated in production will bloom and bear fruit at the seedling stage (saplings or 1-2-year-old young trees, hereinafter referred to as "saplings"); Because the saplings consume a lot of nutrients for flowering and fruiting, which may lead to slow growth of citrus saplings and a delay in entering the high-yield period. Varieties with a high fruit setting rate may cause saplings to yellow, decline, become susceptible to disease, or even die.

Therefore, measures need to be taken in production to prevent citrus saplings from flowering, but many citrus varieties are prone to flowering, and if you are not careful, a large number of flower buds will form, and the tree will be full of flowers and fruit.

At present, in the production of citrus, the solution is mainly to manually erase flower buds, remove flower buds, or remove flowers, remove young fruits, etc., to prevent the young trees from blooming and fruiting, so as to reduce the adverse effects of flowering and fruiting on the growth of young trees. This kind of manual method is very time-consuming and labor-intensive. It is not only costly, but also slow. Now that the rural labor force is aging and scarce, it is difficult to implement it in production.
