Problems solved by technology

At present, there are many kinds of plant growth regulators used in production, among which ethephon and paclobutrazol are mainly used to reduce plant height and prevent lodging, but at the same time, the side effects are to limit the growth of stems and reduce the yield of cane stems and sucrose;30 Alkanols, brassinolides, etc. can improve photosynthetic performance and prevent premature aging, but cannot effectively prevent lodging

Embodiment 1

[0036] Dissolve 1.5g of sodium naphthalene acetate in 5ml of water and completely dissolve to obtain solution I; dissolve 8g of hymexazol in 10ml of water to obtain solution II; then take 13g of ethephon and add it to 20ml of water to obtain solution after completely dissolving III: Mix solution I, solution II and solution III, add 1ml of Tween 20, shake well, and finally adjust the volume to 100ml with water to obtain the sugarcane anti-lodging and anti-decay high-light efficiency anti-lodging and yield-increasing regulator of the present invention.

Embodiment 2

[0038] Dissolve 2g of sodium naphthalene acetate in 5ml of water and completely dissolve to obtain solution I; dissolve 5g of hymexazol in 10ml of water to obtain solution II; then take 13g of ethephon and add it to 20ml of water to obtain solution III after completely dissolving ; Mix solution I, solution II and solution III, add 1ml Tween 20, shake well, and finally set the volume to 100ml with water to obtain the sugarcane anti-lodging and anti-decay high light efficiency anti-lodging yield increase regulator of the present invention.

Embodiment 3

[0040] Dissolve 2g of sodium naphthalene acetate in 5ml of water and completely dissolve to obtain solution I; dissolve 8g of hymexazol in 10ml of water to obtain solution II; then take 11g of ethephon and add it to 6ml of water to obtain solution III after completely dissolving ; Mix solution I, solution II and solution III, add 1ml Tween 20, shake well, and finally set the volume to 100ml with water to obtain the sugarcane anti-lodging and anti-decay high light efficiency anti-lodging yield increase regulator of the present invention.

Abstract

The invention relates to a sugarcane root-promoting, lodging-resistant, yield-increasing regulator, a preparation method and application thereof. The conditioner contains the following components: sodium naphthalene acetate 15‑20g / L, hymexazol 50‑80g / L, ethephon 110‑150g / L, active agent and spreading agent 5‑20g / L, water 730‑ 820g / L. The active agent and spreading agent are selected from one or more of Tween 20, Tween 60 and Triton. The regulator of the present invention can significantly increase the number of seed roots and seedling roots of sugarcane, and has a well-developed root system; strong tillering ability, high stem formation rate, thick stems, strong lodging resistance, high sugar content and sugar yield; sugarcane lodging rate is reduced by 17.40 %‑37.50%, the yield per mu increased by 11.67%‑51.20%, the sugar yield per mu increased by 14.62%‑55.19%, and the sugar content in cane stems increased by more than 4%. At the same time, the product has the characteristics of low cost, convenient use, and less residue in the field, and is easy to popularize and apply, which has a positive role in promoting sugarcane production in my country.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a preparation method and application of a sugarcane root-stimulating, lodging-resistant, and yield-increasing regulator. Background technique [0002] Sugarcane is the main sugar crop, and sucrose is an indispensable food in the life of our people. Sugarcane likes temperature, humidity, and fertilizer, and has a long growing season. It is mainly distributed in tropical and subtropical regions south of 24° north latitude, such as Guangxi, Guangdong, Taiwan, Fujian, Hainan, Yunnan, and Sichuan. During the growth of sugarcane, frequent typhoons, monsoons and heavy rainfall often lead to large-scale lodging of sugarcane, which seriously affects the yield and quality of sugarcane, directly affects the supply of sucrose in people's daily life, and affects the development of sugarcane industry. Therefore, it is of great practical significance for the sustainable development of the sugarcane ...
