preparation example Construction

[0023] The special fertilizer for capsicum in Examples 1 to 3 and Examples 5 to 9 has the same preparation method except for the raw materials and their proportioning ratio, which specifically includes the following steps:

[0024] Step 1. Use the roller press produced by Jiangsu Pengfei Group to roughly grind the attapulgite, and then use the ball mill produced by Jiangsu Pengfei Group to grind the attapulgite after rough grinding to a specific surface area of ​​470-500m 2 / kg of attapulgite powder;

[0025] Step 2: Mix the attapulgite powder and other raw materials evenly according to the ratio to obtain the special fertilizer for pepper.

Embodiment 4

[0026] When preparing the special fertilizer for pepper in Example 4, directly mix each raw material evenly.

[0027] In 2017, the test site was selected in Zunyi Tucheng production base. The pepper variety was Zunla No. 2, and the approval number was Qianshenjiao 2010004. The experiment was carried out on pepper planting sites that had been continuously cropped for 3 years and had similar soil physical properties. 10 blocks, each with an area of ​​560 square meters; 9 of the 10 pepper planting lands were added with the special pepper fertilizer obtained in Examples 1 to 9; the remaining one was used as a control group and BB fertilizer was used as fertilizer. Then all adopt double-row cultivation in Takakuro, the spacing between plants and rows is 28cm×55cm, and the planting and pest control of peppers are carried out according to the existing planting method of Zunla No. 2. The pepper yield and the physical properties of the soil in the test site are tested every year, and t...

Abstract

The invention discloses a fertilizer special for capsicum annuum in the technical field of capsicum annuum planting. The fertilizer is prepared from, by weight, 38-46 parts of a BB fertilizer, 23-29 parts of sulfur coated urea, 35-47 parts of a potassium sulphate type compound fertilizer, 22-28 parts of humic acid, 7-10 parts of attapulgite powder and 0.2-0.5 part of EM bacteria. During preparation, the preparation method comprises the steps of firstly, grinding, wherein attapulgite is ground into the attapulgite powder with the specific surface area higher than 460 m<2> / kg; secondly, mixing,wherein the BB fertilizer, the sulfur coated urea, the potassium sulphate type compound fertilizer, the humic acid, the attapulgite powder and the EM bacteria are evenly mixed to prepare the fertilizer special for the capsicum annuum. In the scheme, the fertilizer special for the capsicum annuum achieves balanced supply of nutrients to capsicum annuum planting land through the interaction of the raw materials, the situation that a beneficial bacterium community is dominant is formed, and the autotoxicity, caused by allelochemicals, of the capsicum annuum is greatly reduced; therefore, the successive cropping obstacle of the capsicum annuum is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of pepper planting, and in particular relates to a special fertilizer for pepper and a preparation method thereof. Background technique [0002] Pepper is an important solanaceous vegetable, and its vitamin C content ranks first among all kinds of vegetables. At present, the total output of chili in my country ranks first in the world, but there are serious obstacles to continuous cropping of chili. According to the survey, the continuous cropping period in pepper producing areas is generally 5 to 10 years, up to 20 years, the incidence rate is as high as 88%, and the dead plant rate is 38% to 85%. In addition, the output of pepper in continuous cropping drops by 10% to 15% in one year and 20% to 30% in two years of continuous cropping. With the increase of the continuous cropping period, the output of pepper gradually decreases, and the obstacle of continuous cropping has become a bottleneck restricting th...
