Embodiment 1

[0039] Take 75 grams of urea, 30 grams of potassium dihydrogen phosphate, 15 grams of borax (17wt% boron content), 0.75 grams of auxin (indole acetic acid), 1.5 grams of 6-benzyl adenine, and 1.5 grams of gibberellin.

[0040] Dissolve urea, potassium dihydrogen phosphate, and borax with a small amount of water; dissolve auxin with 5 times the volume of 95% ethanol solution; dissolve gibberellin with 5 times the volume of 95% ethanol solution ; Dissolve 6-benzyl adenine (6-BA) with 6 times the volume of 1% dilute hydrochloric acid solution. Fully mix the obtained solution, add water to mix evenly, add water to make up to 15 liters, and spray evenly on the surface of cotton leaves from 16:00 to 17:00 in the afternoon on a sunny day with no wind.

[0041] Spray once in the cotton bud stage, the dosage is 15 kg per mu.

[0042] Spray 3 times during the flowering and boll stage, the dosage is 20-25 kg per mu, and the interval between each time is about 1 week.

Embodiment 2

[0045] Take 120 grams of urea, 50 grams of potassium dihydrogen phosphate, 15 grams of borax (11wt% boron content), 0.75 grams of auxin (indole acetic acid), 1.5 grams of 6-benzyl adenine, and 1.5 grams of gibberellin.

[0046] Dissolve auxin with 6 times the volume of 95% ethanol solution; dissolve gibberellin with 6 times the volume of 95% ethanol solution; dissolve 6-benzyl adenine (6-BA) with Dissolve 5 times the volume of 1% dilute hydrochloric acid solution. Mix urea, potassium dihydrogen phosphate, borax and the obtained ethanol solution and dilute hydrochloric acid solution, add water to dissolve, mix well, add water to make up to 15 liters, and spray evenly on the surface of cotton leaves from 16:00 to 17:00 in the afternoon on a sunny day with no wind.

[0047] Spray once in the cotton bud stage, the dosage is 15 kg per mu.

[0048] Spray 2 times during the flowering and boll stage, the dosage is about 25 kg per mu, and the interval between each time is about 1 week...

Embodiment 3

[0051] The foliar fertilizer of embodiment 1 was sprayed 1 time at the cotton bud stage, and the consumption was 15 kilograms per mu.

[0052] The amount of nitrogen fertilizer and phosphorus and potassium compound fertilizer can be increased in the flowering and boll stage. Get 200 grams of urea, 100 grams of potassium dihydrogen phosphate, 20 grams of borax (17wt% boron content), 1 gram of auxin, 2 grams of 6-benzyl adenine, and 2 grams of gibberellin. The preparation method is the same as in Example 1. Dilute to 20 liters, and spray evenly on the surface of cotton leaves from 16:00 to 17:00 in the afternoon on a sunny day without wind; spray 3 times at the flowering and boll stage, the dosage is 20-25 kg per mu, and the interval between each time is about 1 week .

[0053] Compared with the control treatment of spraying and clearing water, spraying the foliar fertilizer of the present invention has a remarkable yield increasing effect, the number of bolls per plant increas...

Abstract

The invention relates to a foliage fertilizer for promoting growth of cotton buds and bolls. The foliage fertilizer is an aqueous solution, and prepared from the following active ingredients: a nitrogen fertilizer, monopotassium phosphate, borax, auxin, 6-benzyladenine and gibberellin. The invention also relates to a preparation method of the foliage fertilizer. By adopting foliage spraying of the foliage fertilizer provided by the invention at a cotton bud period and a boll period, reproductive growth of the cotton can be facilitated; budding and flowering are facilitated; dropping of the cotton buds and bolls is reduced. Thus, the cotton yield is improved. The preparation method of the foliage fertilizer provided by the invention is simple and convenient to operate, and mild in technological condition.

Description

technical field [0001] The invention relates to the field of agricultural fertilizer production, in particular to a foliar fertilizer capable of promoting the development of cotton buds and bolls and a preparation method thereof. Background technique [0002] Cotton is an important economic crop in my country, and lint production is the economic output of cotton. The bud development of cotton determines the economic yield of cotton to a certain extent. Spraying foliar fertilizers during the cotton bud stage and flowering boll stage can promote the growth and development of cotton buds and reduce the shedding of buds and bolls, thereby increasing the lint yield. [0003] At present, there are many types of foliar fertilizers suitable for use in the market, but foliar fertilizers suitable for cotton are still rare, and the cost performance is not high, and the effect is not ideal. Contents of the invention [0004] In order to overcome the defect that there are few kinds o...
