A kind of plant growth regulator for oak tree and its preparation method and application method

Abstract

The invention discloses a plant growth regulator for an oak tree. The plant growth regulator is prepared from the following raw materials by weight: 150-250 parts of 2-4D butyl ester, 250-350 parts of chlormequat chloride, and 900000-1200000 parts of water. Compared with the prior art, after the provided plant growth regulator is used in spraying, a leaf of the oak tree matures 20 days later, the leaf yield of an oak tree garden is increased by more than four times compared with the yield of a tender shoot, the amount of labor used in growing and transferring a tussah is reduced by two thirds, and the plant growth regulator is favorable for large-scale breeding of the tussah. The moisture content and the maturity of the processed leaf of the oak tree are better than those of the tender shoot, and the processed leaf of the oak tree is more suitable for the tussah to eat to grow. The oak tree garden is not exposed, thereby being beneficial for the environmentally friendliness of the oak tree garden.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulators, and in particular relates to a plant growth regulator for oak trees and a preparation method and application method thereof. Background technique [0002] Tussah silkworm production utilizes the resource of oak trees. The leaves of oak trees in Henan Province are affected by the dry and hot wind from the middle and late May to the first ten days of June. The leaves of oak trees are aging and hardening, which is not suitable for eating by tussah silkworms. In order to solve this problem, silkworm farmers cut down the oak trees in winter, and use the new cuts to raise tussah silkworms for stronger silkworms. [0003] There are the following problems in raising tussah silkworms with fire buds after pruning (the oak tree is cut from the root in winter, and the tender shoots in the spring of the second year are called fire buds): [0004] 1. The amount of leaves is small, and the lea...

AI Technical Summary

Problems solved by technology

[0004] 1. The amount of leaves is small, and the leaf production of fire buds is less than 25% of the annual oak leaves. The amount of tussah silkworms that can be stocked per plant is small, and the labor required for tussah silkworms to grow stronger and move silkworms is large, which is not conducive to large-scale stocking of tussah silkworms

[0005] 2. The leaf quality is poor. Most of the fire bud leaves are immature leaves with high moisture content, which cannot meet the nutritional needs of tussah silkworms.

[0006] 3. It is not conducive to environmental protection. The oak garden has been exposed for nearly 5 months after cutting, which is easy to cause soil erosion
