Problems solved by technology

At present, there are many kinds of plant growth regulators used in production. Among them, paclobutrazol, uniconazole, and choline chloride are mainly used to reduce plant height and prevent lodging, but at the same time, the side effects are to limit ear growth and reduce yield. ; Triacontanol, brassinolide, etc. can improve photosynthetic performance, but cannot effectively prevent lodging

Embodiment 1

[0035] First, add 50g of potassium polyaspartate to 100ml of water, after completely dissolving, add 36g of copper sulfate to form a dark blue complex solution I; then, add 95g of ethephon and 250g of choline chloride to 500ml of water successively, After complete dissolution, solution II was formed. After that, solution I and solution II were mixed, 20 ml of Tween 20 was added, and the volume was made up to 1000 ml with water.

Embodiment 2

[0037] First, add 50g of potassium polyaspartate to 100ml of water, after completely dissolving, add 36g of copper sulfate to form a dark blue complex solution I; After that, add 95g of ethephon and 350g of choline chloride to 500ml of water successively, After complete dissolution, solution II was formed. After that, solution I and solution II were mixed, 20 ml of Tween 20 was added, and the volume was made up to 1000 ml with water.

Embodiment 3

[0039] First, add 50g of potassium polyaspartate to 100ml of water, after completely dissolving, add 36g of copper sulfate to form a dark blue complex solution I; then, add 135g of ethephon and 250g of choline chloride to 500ml of water successively, After complete dissolution, solution II was formed. After that, solution I and solution II were mixed, 20 ml of Tween 20 was added, and the volume was made up to 1000 ml with water.

Abstract

The invention provides preparation and application of a millet lodging-resistant yield-increasing regulator. The regulator comprises the following components: 93.5-125 g / L of ethephon, 250-280.5 g / L of choline chloride, 36 g / L of copper sulfate, 30-60 g / L of potassium polyaspartate, 20 ml / L of an active agent and a spreader, and the balance of water. Wherein the active agent and the spreader are selected from one or more of Tween 20 and Tween 60. The millet lodging-resistant yield-increasing regulator provided by the invention can significantly enhance the lodging resistance of millet, increase the ear grain weight and the grain yield of millet, and increase the millet yield by 15% or above. Meanwhile, the product has the characteristics of low cost, convenience in use, few field residuesand the like, is easy to popularize and apply, and has a positive promotion effect on millet production in China.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to the preparation and application of a millet anti-lodging and yield-increasing regulator. Background technique [0002] Millet is a traditional dominant crop and drought-resistant and barren-resistant crop. It has the physiological characteristics of drought resistance and water saving, and has a wide range of ecological adaptability. Studies have shown that millet is naturally nutritious, with a protein content of 11.2%-13.4%, and a fat content of 4.5%. Protein and fat are higher than those of rice and wheat flour; millet contains 8 kinds of amino acids necessary for the human body, which are rich in content and balanced in proportion. Among them, the content of lysine is 0.22%-5.24%, the content of methionine is 0.4%, and the content of tryptophan is 0.25% %, the content of leucine is 1.87%, and the content of threonine, isoleucine and valine is between 0.42% and 2.88%; the content of ...
