Problems solved by technology

[0005] The disadvantages of the above-mentioned base calcium fertilizers are that it is time-consuming and labor-intensive to use, and the cost is high; the disadvantage of the second type of root topdressing is that calcium fertilizers cannot be mixed with phosphate ions, and cannot provide comprehensive nutrition at the same time, resulting in a waste of working hours and poor use effects.

Embodiment 1

[0029] To prepare high-concentration liquid compound fertilizer to prevent watermelon cracking, heat 300 grams of water to 50°C, add 50 grams of chelated trace elements, namely 12.5 grams of EDTA-Cu, 12.5 grams of EDTA-Fe, 12.5 grams of EDTA-Mn, and 12.5 grams of EDTA -Mixture composed of Zn, after being completely dissolved, add 200 grams of ammonium polyphosphate, 300 grams of potassium formate after being completely dissolved, and 150 grams of calcium nitrate after being completely dissolved.

[0030] From May to July 2014, researchers conducted experiments on watermelons in the greenhouses of Qinglan Agricultural Products Professional Cooperative in Jurong City. The variety was 8424. Watermelons in the same greenhouse were selected for comparative experiments. Liquid compound fertilizer, the period of use for the first time is 7 days after blooming, spraying for the second time after interval 10 days, every time the liquid compound fertilizer of spraying gained is diluted 3...

Embodiment 2

[0032] Prepare high-concentration liquid compound fertilizer to prevent watermelon from cracking melon, prepare 1000 grams of high-concentration liquid compound fertilizer to prevent watermelon from cracking melon, heat 350 grams of water to 60 ° C, add 60 grams of chelated trace elements, namely 15 grams of EDTA-Cu, 15 grams of The mixture composed of EDTA-Fe, 15 grams of EDTA-Mn and 15 grams of EDTA-Zn, after being completely dissolved, add 300 grams of ammonium polyphosphate, 200 grams of potassium formate after being completely dissolved, and 100 grams of calcium nitrate after being completely dissolved.

[0033] From April to July 2014, the researchers used this fertilizer on watermelons at the Jurong City Cultivated Land Quality Protection Station to conduct a comparative test on watermelons in the same shed. The experimental group sprayed the liquid compound fertilizer three times on the leaves. The first use period is 7 days after flowering, spray the second time after ...

Embodiment 3

[0035] To prepare high-concentration liquid compound fertilizer to prevent watermelon cracking, heat 400 grams of water to 70°C, add 100 grams of chelated trace elements, namely 25 grams of EDTA-Cu, 25 grams of EDTA-Fe, 25 grams of EDTA-Mn, and 25 grams of EDTA -Mixture composed of Zn, after being completely dissolved, add 400 grams of ammonium polyphosphate, 400 grams of potassium formate after being completely dissolved, and 200 grams of calcium nitrate after being completely dissolved.

[0036] From April to July 2014, researchers used this fertilizer to test on watermelons in Dongtai City, and selected watermelons in the same shed for comparative experiments. The experimental group was treated with drip irrigation, and the first application period was 7 days after flowering. Drip irrigation is the second time after 20 days, and the gained liquid compound fertilizer of applying at every turn is diluted 500 times with water, uses this liquid compound fertilizer of 3000 grams ...

Abstract

The invention discloses liquid compound fertilizer preventing watermelons from cracking. The liquid compound fertilizer comprises, by weight, 30-40 parts of water, 20-40 parts of ammonium polyphosphate, 20-40 parts of potassium organo-carboxylate, 10-20 parts of calcium salt and 5-10 parts of microelements. A preparation method includes the step that microelements, ammonium polyphosphate, potassium organo-carboxylate and calcium salt are sequentially added to water in proportion, and then the liquid compound fertilizer preventing watermelons from cracking is obtained. The liquid compound fertilizer has the advantages that nutrient elements are comprehensive, soil nutrients are adjusted to be balanced after the fertilizer is used, and various elements needed by plants can be quickly supplemented in time; perfect coexistence of phosphorus and calcium is achieved, no sediment is generated, and the absorption efficiency is high; the fertilizer is neutral after being diluted, plant absorption is more facilitated, the fertilizer can be mixed with most non-alkaline pesticide for use in the using process, and production and use are more convenient; the production process is simple, raw materials are universal, cost is low, use is convenient, and popularization is easy.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a preparation method and application of a liquid compound fertilizer for preventing watermelons from cracking. Background technique [0002] Calcium is one of the important weight elements needed for plant growth. Calcium is a component of cell membrane and pectin, and plays an important role in the transportation of substances in plants. A large part of the calcium in plants exists in the cell wall, which can be combined with pectin to calcium pectinate, which can also strengthen the structure of the cell wall and regulate the permeability of the cell membrane. Therefore, adding an appropriate amount of calcium to watermelon will effectively prevent the watermelon from cracking during the growth process, and also have a certain preventive effect on deformed melons, which is very important for increasing yield and improving quality. [0003] At present, there ...
