Embodiment 1

[0026] In this embodiment, a formula of watermelon nutrient solution uses water as a solvent, and 800-1200 mg of calcium nitrate, 200-500 mg of potassium nitrate, 150-350 mg of magnesium sulfate, and 150-300 mg of superphosphate are added to each liter of water. mg, potassium sulfate 80~150 mg, ammonium dihydrogen phosphate 300~500 mg, sodium chloride 100~200 mg, boric acid 5~10 mg, copper sulfate 0.03~0.07 mg, sodium silicate 1~3 mg and plant auxin 2~5 mg to configure the solution.

[0027] This program provides calcium and nitrogen elements for the growth of watermelons by using calcium nitrate;

[0028] Use potassium nitrate to provide potassium and nitrogen for the growth of watermelon;

[0029] Using magnesium sulfate to provide sulfur and magnesium for the growth of watermelons;

[0030] Use superphosphate to provide calcium and phosphorus for the growth of watermelons;

[0031] Use potassium sulfate to provide sulfur and potassium for the growth of watermelons;

Embodiment 2

[0038] In the present embodiment, a watermelon nutrient solution formula uses water as a solvent, and each liter of water contains 800 mg of calcium nitrate, 200 mg of potassium nitrate, 150 mg of magnesium sulfate, 150 mg of superphosphate, and 150 mg of potassium sulfate. mg, ammonium dihydrogen phosphate 500 mg, sodium chloride 200 mg, boric acid 10 mg, copper sulfate 0.07 mg, sodium silicate 3 mg and auxin 5 mg. This formula is suitable for the germination stage of watermelon seeds, can promote the germination of watermelon seeds, increase the activity of watermelon seeds and the ability to absorb nutrients, help to improve the survival rate of watermelon seeds, and shorten the period of watermelon seed germination.

Embodiment 3

[0040] In the present embodiment, a watermelon nutrient solution formula uses water as a solvent, and each liter of water contains 1000 mg of calcium nitrate, 350 mg of potassium nitrate, 200 mg of magnesium sulfate, 250 mg of superphosphate, and 120 mg of potassium sulfate. mg, 420 mg of ammonium dihydrogen phosphate, 130 mg of sodium chloride, 7 mg of boric acid, 0.05 mg of copper sulfate, 2 mg of sodium silicate and 3.5 mg of auxin. This formula is suitable for the vegetative growth stage of watermelon seedlings. It can provide a large amount of nitrogen, phosphorus and potassium elements for the growth of watermelon seedlings to promote the growth of watermelons, and improve the disease resistance and insect resistance of watermelons, which is conducive to improving the survival rate of watermelons.

Abstract

The invention discloses a formula for a watermelon nutrient solution. Water is taken as a solvent. The solution is prepared in the manner of adding 800-1200mg of calcium nitrate, 200-500mg of potassium nitrate, 150-350mg of magnesium sulfate, 150-300mg of calcium superphosphate, 80-150mg of potassium sulfate, 300-500mg of ammonium dihydrogen phosphate, 100-200mg of sodium chloride, 5-10mg of boricacid, 0.03-0.07mg of copper sulfate, 1-3mg of sodium silicate and 2-5mg of phytohormone into 1L water. The invention has the beneficial effects: sufficient necessary elements and necessary microelements can be supplied by the formula for the growth of the watermelon so that the formula can meet the growth requirement of the watermelon, the phytohormone is used for promoting the plant growth, thesurvival rate of the watermelon is increased and the growth speed of the watermelon is increased.

Description

technical field [0001] The invention relates to the field of watermelon planting, in particular to a formula of watermelon nutrient solution. Background technique [0002] The amount of cultivation of fruits and vegetables is large, occupying a lot of farmland, and consuming a lot of manpower and material resources. Especially in areas with poor soil, planting crops with sand as a substrate (sand culture) can better solve this problem. Sand culture is a new type of soilless cultivation method. Fruits and vegetables are planted on the sandy soil, and the nutrient solution is continuously dripped into the substrate by installing a dropper to provide water, nutrients, and oxygen for the plants, so that the plants can grow normally and complete their entire life. The cycle is different from the cultivation under the traditional soil cultivation form, and after planting a crop, the river sand can be reused after washing. The sand culture nutrient solution formula is the core of ...
