Zinc-rich culture solution for soilless culture of brasenia schreberi and preparation device thereof

Abstract

The invention discloses a zinc-rich solution for soilless culture of brasenia schreberi and a preparation device thereof, belonging to the technical field of soilless culture of intelligence-developing vegetables. The zinc-rich culture solution for soilless culture of brasenia schreberi comprises the following formulated raw materials: an aqueous solution, potassium nitrate, magnesium sulfate, ammonium sulfate, calcium superphosphate, a pH value regulator and trace elements. The preparation device of the zinc-rich culture solution for soilless culture of brasenia schreberi comprises a box body, wherein a shell is fixedly installed at the bottom of the box body. The zinc-richculture solution for soilless culture of brasenia schreberi breaks through the limitations of tedious procedures, high production cost, low product uniformity and harsh production conditions of traditional brasenia schreberi planting, solves the problems of cost for manual dreg selection and manual weeding of dirty brasenia schreberi, and improves the zinc element content and neatness of brasenia schreberi; and the soilless culture of brasenia schreberi improves the quality of brasenia schreberi, the problem that brasenia schreberi is difficult to pick can be well solved while planting is facilitated, the planting area of brasenia schreberi is enlarged, and the practicability of the culture solution is effectively improved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation of intelligence-enhancing vegetables, in particular to a zinc-rich soilless cultivation water shield culture liquid and a preparation device thereof. Background technique [0002] Soilless cultivation is mainly aimed at the cultivation of water shield. The ratio of nitrogen, phosphorus, potassium, calcium and magnesium absorbed by water shield is 1.49:1.71:1.0:1.1:0.28, which requires a relatively high phosphorus content in the soil. High, water shield grows in paddy fields, and the planting is cumbersome. During the growth period, it takes a lot of manpower to remove weeds. In addition, the quality of water shield in paddy fields is low, and the dregs need to be manually selected and cleaned many times. This process is complicated, the workload is heavy, and the production cost is high. High, secondly, water shield can enrich the zinc element in the environment, which is essential fo...

[0002] Soilless cultivation is mainly aimed at the cultivation of water shield. The ratio of nitrogen, phosphorus, potassium, calcium and magnesium absorbed by water shield is 1.49:1.71:1.0:1.1:0.28, which requires a relatively high phosphorus content in the soil. High, water shield grows in paddy fields, and the planting is cumbersome. During the growth period, it takes a lot of manpower to remove weeds. In addition, the quality of water shield in paddy fields is low, and the dregs need to be manually selected and cleaned many times. This process is complicated, the workload is heavy, and the production cost is high. High, secondly, water shield can enrich the zinc element in the environment, which is essential for children's intellectual development and metabolism, but the supply of zinc element in the natural environment is not stable enough, so soilless cultivation is one of the methods to improve the yield and quality of water shield. It is also a necessary improvement method to reduce production costs, and the soilless cultivation culture solution is the core technology of soilless cultivation. For example, the patent with the publication number of CN108849450A mainly innovates with soilless cultivation of water shield, but the nutrient solution in it, the nutrient The elements are not sufficient enough to improve the quality of water shield, therefore, a zinc-rich soilless cultivation water shield culture solution and its preparation device are now proposed
