[0073]Embodiments of the present invention also include a method for preparing a nutrient solution for improving seed setting rate, comprising the following steps:
[0074] 0.1-2 parts of brassinolide, 0.1-2 parts of diethyl diethyl ethyl, 0.1-3 parts of indole-3-acetic acid, 0.1-2 parts of naphthalene acetic acid, 0.1-2 parts of forchlorfenuron , 10-50 parts of C2-C5 alcohol and 50,000-120,000 parts of water are evenly mixed to obtain a nutrient solution for improving the seed setting rate.
[0075] After testing, and considering the solubility of indole-3-acetic acid, naphthaleneacetic acid, and forchlorfenuron, preferably, 0.1 to 3 parts of indole-3-acetic acid, 0.1 to 2 parts of naphthaleneacetic acid, 0.1 ~2 parts of forchlorfenuron are added to 10~50 parts of C2~C5 alcohol, and after completely dissolving, add 0.1~2 parts of brassinolide, 0.1~2 parts of diethyl diethyl ethyl and 50000~120000 parts of water.
[0076] Through the above method, the uniformity of the obtai...
Embodiment 1
[0080] Add 0.1 part of indole-3-acetic acid, 0.1 part of naphthalene acetic acid, and 0.1 part of forchlorfenuron into 10 parts of ethanol, and after completely dissolving, add 0.1 part of brassinolide and 0.1 part of diethyl diethyl ethyl And the water of 50000 parts, obtain nutrient solution.
Embodiment 2
[0082] Add 3 parts of indole-3-acetic acid, 2 parts of naphthalene acetic acid, and 2 parts of forchlorfenuron into 50 parts of ethanol, and after completely dissolving, add 2 parts of brassinolide, 2 parts of diethyl diethyl ethyl And the water of 120000 parts, obtain nutrient solution.

Abstract
The present invention relates to the field of agriculture, in particular to a nutrient solution for improving seed setting rate, its preparation method and application. The nutrient solution for improving the seed setting rate of the present invention comprises the following components in parts by weight: 0.1 to 2 parts of brassinolide; 0.1 to 2 parts of diethyl hexanoate; 0.1 to 3 parts of indole-3- Acetic acid; 0.1-2 parts of naphthaleneacetic acid; 0.1-2 parts of forchlorfenuron; 10-50 parts of C2-C5 alcohol; 50000-120000 parts of water. The nutrient solution of the invention is applied during the pollination period of the Malvaceae distant hybrid crops, effectively improving the seed setting rate of the distant hybrid young bolls and reducing the shedding rate of the distant hybrid young bolls.
Description
technical field [0001] The invention relates to the field of agriculture, in particular to a nutrient solution for improving seed setting rate, its preparation method and application. Background technique [0002] Upland cotton is a commercial crop rich in genetic and phenotypic traits, belonging to the family Malvaceae and the genus Gossypium. After years of artificial domestication and directional cultivation, the genetic basis of upland cotton has become increasingly narrow, making it more and more difficult to improve quality and yield. Distant hybridization is one of the effective ways to achieve the above problems. [0003] Golden flower sunflower, also known as cabbage hibiscus and wild hibiscus, is an annual herb belonging to Malvaceae and Okra, and has the habit of unlimited flowering and fruiting like cotton. It has a certain degree of natural resistance to aphids and spider mite, and can secrete a salt crystal particle on the petiole and the back of the leaf, bu...
