Problems solved by technology

[0002] At present, the fertilizers in the prior art include urea, potassium fertilizer, and phosphorus fertilizer, etc. These fertilizers have a certain growth-promoting effect on crops, but there are some problems in these fertilizers, such as the proportion of ammonium phosphorus and potassium is not out of balance, and cannot meet the needs of plants. Nutrient demand; also some fertilizers have poor improvement to soil, especially saline-alkali soil, after using the fertilizer in the prior art, make soil quality degenerate, be unfavorable for the annual output growth of crop; Simultaneously, use these fertilizers, can not Effectively improve the quality of crop fruits
And the lack of fertilizer calcium and boron in the prior art directly affects the growth of crop growth points, affects the formation of flowers and fruits, and causes such as "black heart disease" of cabbage, "bran heart disease" of radish, "cracking fruit" of citrus, and "fruit cracking" of tomato. Navel rot” and other phenomena, calcium-boron compound fertilizers are rare in China, and a few liquid fertilizers are simply calcium nitrate and borax dissolved in water, and the absorption and utilization rate of crops is low.

Embodiment 1

[0023] In this embodiment, the above calcium and boron chemical fertilizers are used in the test. The test is carried out in Xiyanfang Village, Weishanzhuang Town, Daxing District, and the Grand Canal Serving Vegetable Center Base, Tongzhou District. The specific conditions of the two test sites are as follows:

[0024] Xiyanfang Village, Weishanzhuang Town, Daxing District: The small rapeseed variety is "Huaguan", and the area of ​​the community is 20m 2 , the test rapeseed was first planted and harvested 20 days later. Before planting, apply cow dung as a base fertilizer at a rate of 1670 kg / mu. During this period, handle two sprays of clear water three times, process three sprays of 1000 times dilution of calcium boron chemical fertilizer of the present invention three times, and irrigate three times, and the amount of irrigation water is about 24 cubic meters per mu.

[0025] Tongzhou District Grand Canal Side Vegetable Center Base: The small rapeseed variety is "Jingyou ...

Embodiment 2

[0031] In the embodiment of the present invention, boron has the effect of promoting the absorption of calcium, promoting the transfer of nutrients produced by the leaves to the fruit, and promoting the effect of flowering and fruiting; spraying the calcium-boron chemical fertilizer of the previous embodiment of the present invention can increase the pectin content of the fruit, and can strengthen the intercellular space. The toughness of the joint has the effect of reducing the incidence of fruit cracking and navel rot. The calcium-boron chemical fertilizer of embodiment before the present invention carries out field comparative test, and test result report is as follows:

[0032] 1. Purpose of the test

[0033] Apply the calcium boron chemical fertilizer of the embodiment of the present invention to tomatoes and celery to confirm its yield-increasing effect.

[0034] 2. Location

[0035] 2.1 Test site and test soil

Abstract

The invention discloses a calcium-boron compound fertilizer. The raw materials of the calcium-boron compound fertilizer comprise the following components in percentage by weight: 43-70% of calcium chloride, 20-48% of sodium borate, 4-9.1% of citric acid, 0.2-2% of sodium citrate, 0.2-1.5% of EDTA-2Na (ethylene diamine tetraacetic acid-2Na) and 0.2-1.5% of sodium tripolyphosphate. The finished compound fertilizer product comprises the following components in percentage by weight: 15-24% of calcium and 4-10% of boron. The invention also provides a preparation method of the calcium-boron compound fertilizer, which comprises the following steps: (1) respectively weighing the calcium chloride, sodium borate, citric acid, sodium citrate, EDTA-2Na and sodium tripolyphosphate; (2) grinding every raw material into granules by using a grinder, and passing the granules through a 50-mesh screen for later use; (3) after grinding, respectively adding the calcium chloride, EDTA-2Na, sodium tripolyphosphate, and part of citric acid and sodium citrate into a V-shaped mixing machine with a jacket, and stirring for 20 minutes, wherein in the stirring process, the humidity is controlled at 1-2%, and the temperature is controlled at 120-150 Fahrenheit degrees; (4) adding the sodium borate, and stirring for 20 minutes while continuing keeping the temperature and humidity; and (5) regulating the pH value to 3-6 with the citric acid and sodium citrate. Calcium and boron in the fertilizer are scientifically proportioned to obtain the fertilizer with rich nutrients, and the fertilizer can be used for producing excellent fruits and crops.
