Background
Due to the discharge of human domestic sewage and the use of a large amount of agricultural chemical fertilizers, rivers and lakes around rural areas in China are polluted (eutrophicated) to different degrees, so that a large amount of propagation of various aquatic plants and microorganisms is caused, and the water quality is seriously polluted. Meanwhile, the polluted river water or lake water also permeates into the underground water system, and causes pollution of the underground water. In order to solve the serious environmental problem of river water and lake water pollution, scientific researchers develop a method for controlling polluted water bodies by planting fast-growing aquatic plants, namely water hyacinth, and enabling the water hyacinth to absorb nutrient substances in the river water or the lake water. However, because of the mass multiplication of the water hyacinth, if the water hyacinth is not removed in time, secondary pollution is caused to river water or lake water, and thus the problem of more serious water pollution is caused, so how to change waste into valuable is the key for solving the water pollution.

The method for preparing the plant nutrient solution provided by the invention comprises the following steps: and uniformly mixing the components according to the proportion to obtain the plant nutrient solution.
In actual production, each component in the plant nutrient solution can be independently packaged according to actual needs.
In addition, the application of the plant nutrient solution provided by the invention in the cultivation of crops and the application in improving the yield of the crops also belong to the protection scope of the invention. Wherein. The cultivation can be soilless cultivation or soil cultivation; in the cultivation step, the cultivation temperature can be specifically 10-30 ℃;
the using amount of the plant nutrient solution is regularly and quantitatively supplied according to different growth and development periods of different crops, and the specific operation method is the same as the supplying method of the nutrient solution in soilless culture;
the use mode of the plant nutrient solution is spray irrigation or drip irrigation;
the using time of the plant nutrient solution is the seedling raising period of crops and the whole growth and development period after field planting.
In addition, the plant nutrient solution after being mixed uniformly can be diluted into different proportions by adding water according to different types of horticultural crops.
The crops can be horticultural crops, and more specifically can be any one selected from tomato, eggplant, green pepper, cucumber, melon, watermelon, wax gourd, pumpkin, lettuce, celery, leek, shallot, beans, rose, carnation, herbaceous flowers, strawberry, apple, pear, peach, grape and mandarin orange; wherein the beans are selected from any one of kidney beans, cowpeas and peas; the grass and flower can be selected from any one of fructus Mali Pumilae, herba Violae Hortensis and herba Lissampelotis ananati.
The invention prepares the water hyacinth juice (organic matter) for pollution treatment into the plant nutrient solution for cultivation of horticultural crops. The application range of the method can be used for soil cultivation and can also be used for soilless cultivation. The soilless culture has the advantage that horticultural crops can be planted in the nutrient solution regardless of the soil quality of the soil, even in places without defects such as deserts, gobi, deserts or islands. And the yield of the horticultural crops can be doubled, and annual production can be realized through greenhouse cultivation. Therefore, the problem of secondary pollution of the water hyacinth can be solved, and the high-efficiency production of garden crops such as vegetables, fruits and the like can be realized by using wastes.
Each horticultural crop requires different nutrients due to the different nutrient requirements of the different horticultural crops. The growth and development of all horticultural crops cannot be met only by using the water hyacinth juice, but if a method for preparing the nutrient solution with the specificity of the crops is used according to the difference of the requirements of different horticultural crops on nutrient substances, the production process is complex, and farmers are very inconvenient to use. The nutrient solution provided by the invention is a universal nutrient solution, can be diluted into the nutrient solution suitable for the growth and development of different crops according to the requirements of the crops according to a certain proportion, and thoroughly solves the problem of secondary pollution of the water hyacinth.
The nutrient solution formula provided by the invention belongs to balanced nutrition, and the concentration ranges of various nutrient substances such as N, P, K, Ga, Mg, S, Fe, Mn, Zn, B, Mo and the like are suitable for different growth and development stages of various horticultural crops. The yield of the horticultural crops planted by the organic nutrient solution can be greatly increased, for example, the yield of tomatoes can reach about 2 ten thousand kilograms per mu, the yield of cucumbers reaches 1-1.5 ten thousand kilograms per mu, and the yield of strawberries reaches 1500-3000 kilograms per mu. The yield of other various horticultural crops can be greatly improved.
