Adjusting fertilizer special for cotton

A technology of cotton and content, applied in the direction of application, fertilization device, fertilizer mixture, etc., can solve the problems that the farmers who use only the regulator are difficult to grasp, and the single-use trace element fertilizer effect is not long, so as to increase the leaf growth function and improve disease resistance. Ability to prolong flowering time

Embodiment Construction

[0014] Below in conjunction with specific embodiment the present invention is described in detail as follows:

[0015] 10g of substance A, 100g of substance B, 600g of substance C, CuSO 4 50g, CaCl 2 20g and MgCl 2 20g were crushed to 200 mesh respectively, mixed well, divided into 20g packs to make regulators.

[0016] In 2007, it was tested in rural cotton planting areas such as Li County, Anxiang County, and Dingcheng District in Changde City, Hunan Province.

[0017] The application method is as follows: the specific application time of cotton is subject to the physiological index

[0018] For the first time (early bud stage), every mu uses 10 grams of conditioning agent of the present invention and mixes 10 kilograms of water, stirs, dissolves;

[0019] For the second time (full bud stage), every mu uses regulator 20g of the present invention, mixes 15 kilograms of water, stirs, dissolves;

[0020] For the third time (initial flowering stage), every mu uses regulator...

Abstract

The invention relates to an adjustive fertilizer special for cotton, according to weight proportion, compositions of the fertilizer comprise the following three substances: (1) chemical name: mepiquat chloride, white or hoar crystallinesubstance, the content is between 1 and 1.5g; (2) chemical name: 2,4a,7-Trihydroxy-1-methyl-8-methylenegibb-3-ene-1,10-dicarboxylic acid 1,4a-lactone, white crystalline powder, the content is between 4 and 20g; (3) sodium borate, Na2B4O7, white crystalline powder, the content is between 50 and 70g. The compositions are crushed, mixed evenly, weighed, and packaged separately; and a regulator in 10g of the fertilizer is added with 6 to 13 kg of water, mixed evenly and dissolved to prepare into spraying liquid which is evenly sprayed on leaf surfaces. The regulator applied can coordinate contradiction of crop growth and fruit nutrient, increase growth function of leaves, improve the ability to resist disease and cold, improve the ratio of female flowers and male flowers, prolong the flowering time, reduce the falling of buds, flowers and bolls, improve boll setting ratio and increase the output by more than 20 percent.

Description

technical field [0001] The invention relates to an agricultural fertilizer, that is, a special conditioner for cotton. Background technique [0002] At present, similar products used on cotton mainly use regulators such as trace elements and regulators alone. Although trace elements can increase the photosynthesis of leaves, prolong the functional period of cotton leaves, and improve the photosynthetic utilization rate of leaves, the fertilizer effect is not long. The number of times of use is large, which greatly increases the cost of farmers, and is also somewhat inconvenient. Although regulating pyridine can shorten internodes, reduce cotton boll shedding, and enhance boll formation, it is difficult for farmers to grasp it. Improper application often causes seedling damage and reduces yield. Periods of high heat or improper fertilization can cause buds to fall off, reducing yields. Contents of the invention [0003] In order to overcome the disadvantages that the sing...
