Embodiment Construction

[0076] figure 1 It is a sectional view of a planting device used in the present invention. The device is composed of two three-dimensional planting boards 1 lapped together at the upper end, the lower end is placed in the return flow tank 6, and the two ends are closed to form a horizontal triangular prism-shaped airtight space. There are multiple planting holes on the planting plate 1, and there are planting bodies made of sponge or other materials in the planting holes, so that the seeds are attached to the holes; a set of nutrient solution aerosol supply system is equipped in the closed space, and the system includes high-pressure The water pipe 5 and a plurality of shower heads 4 communicated with the water pipe, and the high-pressure water pipe 5 can be attached to the bracket 3, or can be suspended in the air in a stereotyped manner. The nutrient solution is sprayed out in the form of aerosol through the nozzle 4. Usually, when the nutrient solution reaches the nozzle, ...

Abstract

The invention provides plant cultivation seawater nutrient solution. The nutrient solution consists of the following four parts: a part A consisting of 520 to 630g of Ca(NO3)2.4H2O and 360 to 440g of KNO3, a part B consisting of 100 to 170g of KH2PO4 and 170 to 250g of MgSO4.7H2O, a part C consisting of 22 to 33g of FeSO4.7H2O, 30 to 45g of EDTA-2Na, 2.3 to 3.4g of H3BO3, 1.7 to 2.5g of MnSO4.4H2O, 0.18 to 0.26g of ZnSO4.7H2O and 0.07 to 0.09g of CuSO4.5H2O, and a part D consisting of 5,000 to 7,500g of seawater, wherein 1 to 1.5 times of A, 1 to 1.5 times of B and 1 to 1.5 times of C are mixed together; water is added into the mixture until the amount reaches 1 ton; and 1 to 3 times of D is added into the mixture. The invention also provides a plant spraying cultivation method, in which the nutrient solution is used and sprayed to the roots of plants in the form of fog. During the initial stage of the plant growth, doubled A, doubled B and doubled C are dissolved in every one ton of water, doubled D is added to prepare the nutrient solution, and the nutrient solution is sprayed to the roots of the plants in the form of fog; during the vigorous growing stage of the plant growth, the using amounts of A, B and C are increased to 1.3 to 1.5 times; and during the harvesting stage of the plant growth, the using amount of D is increased to 2 to 3 times.

Description

technical field [0001] The invention relates to a seawater nutrient solution for plant cultivation and a plant seawater nutrient solution spray cultivation method. Background technique [0002] Traditional agriculture is a natural production method based on sunlight and soil matrix. The output and quality of products are restricted by the planting area and natural environmental conditions, and it is difficult to meet people's requirements for food quantity and quality. [0003] Greenhouse cultivation gets rid of the restriction of the environment on agricultural production to a certain extent, and people can eat various vegetables or fruits at any time. Greenhouse soilless cultivation technology is a newest cultivation method researched and adopted along with the development of greenhouse production. Soilless cultivation can be roughly divided into two categories: substrate cultivation and substrateless cultivation. Substrate cultivation, that is, the root system of the cr...
