Embodiment

[0050] Based on the universality and application effect of related plant growth regulators, in this application, the inventors used two plant growth regulators diethylaminohexanoate (DA-6) and chlormequat (CCC) with complementary effects as active ingredients, At the same time, it is considered that the design adopts the spraying method to be suitable for corn. Therefore, an active agent (Triton X-100 is used as an example in the following examples) and a spreading agent (in the following examples, Triton X-100 is used as an example) and a spreading agent (in the following examples) must be added in the final compound. Tween-20 as an example), preservatives (potassium sorbate is taken as an example in the following examples) and other auxiliary materials. Combined with the inventor's understanding of the growth stages of the relevant corn varieties and the comprehensive consideration of factors such as the actual application amount and application timing of the growth regulator...

Embodiment 2

[0090] On the basis of Example 1, based on the treatment method of the D1C3 group (that is, the concentrations of DA-6 and CCC are 15mg / L and 4g / L respectively), combined with the planting density factors in the actual corn planting process, the inventor in 2019 Further experiments were conducted to analyze the effect of the specific compound ratio on the lodging resistance of corn stalks, the resistance of leaves to premature senescence and the yield. The specific experimental situation is briefly introduced as follows.

[0091] In 2019, during the planting experiment, the experimental design was carried out using the split-plot method. The planting variety was the main plot, the planting density was split-plot, and the regulator treatment was split-split plot. Each treatment was repeated 3 times; the planting variety was Zhengdan 958 Hejundan 20, the planting densities of the two varieties are 67,500 plants / hm 2 (Z6.75, X6.75) and 90,000 plants / hm 2 (Z9, X9); the design of...

Abstract

The invention belongs to the technical field of corn cultivation, and particularly relates to a regulator composition for corn stalk strengthening, premature senility resisting and yield increasing and an application patent application of the regulator composition. The regulator composition is prepared by taking diethyl aminoethyl hexanoate DA-6 and chlormequat chloride CCC as effective componentsand compounding, and the composition comprises 15-60 mg/L of diethyl aminoethyl hexanoate and 1-4 g/L of chlormequat chloride. For improving the lodging resistance of corn, improving the premature senility resistance of corn leaves and increase the yield, the compounding ratio of the growth regulator is preliminarily discussed. Furthermore, the application effect is specifically researched and analyzed by combining different corn varieties and different planting densities. Preliminary experiment results show that related production indexes can be obviously improved under the conditions of different corn varieties and different planting densities, particularly, on the basis of ensuring improvement of lodging resistance, yield data of Jundan 20 under the high-density planting condition canbe obviously improved, and a good yield increasing effect is shown.

Description

technical field [0001] The application belongs to the technical field of corn cultivation, and specifically relates to a regulator composition for strengthening corn stalks to resist premature aging and increase yield and the application for a patent application thereof. Background technique [0002] Corn is an important food and feed crop, which plays a pivotal role in ensuring the food security of the world and our country. At present, increasing maize planting density is still an important way and one of the key measures to increase the yield of maize populations. However, as a high-stalk crop, maize is prone to lodging, and excessively high planting density will further increase the risk of maize lodging. [0003] On the other hand, increasing the planting density of corn can also cause premature senescence of leaves. Maize leaves are used as source organs, which utilize light energy, CO 2 It is an important place to synthesize organic compounds with water and plays an...
