Watermelon cultivation substrate adopting water hyacinth as main raw material

Abstract

The invention discloses a watermelon cultivation substrate adopting water hyacinth as a main raw material. The watermelon cultivation substrate is prepared from the following raw materials in parts by weight: 23-25 parts of rapeseed cake meal, 14-18 parts of sawdust, 5-7 parts of potassium dihydrogen phosphate, 3-4 parts of calcium lactate, 1-2 parts of polyacrylic acid, 4-6 parts of blast-furnace slag powder, 45-47 parts of water hyacinth stems and leaves, 12-15 parts of sunflower husk powder and residues, 32-36 parts of snake skin waste, 1.3-1.6 parts of pepsase preparation, 1.8-2.0 parts of 1-(3-dimethylamino propyl)-3-ethyl carbodiimide hydrochloride, 0.4-0.6 part of N-hydroxyl succinimide, a proper volume of 4% sodium chloride solution, a proper volume of 0.15mol / L citric acid solution and a proper volume of water. The cultivation substrate disclosed by the invention is used for solving problems in relatively simple resource-converting utilization of the water hyacinth which is flooded at present, and the water hyacinth is processed and is applied to the cultivation substrate for watermelons, so that the organic content and nutrient richness of the cultivation substrate are increased, meanwhile, the added value of the resource-converting utilization of the water hyacinth is increased, and the economic benefit of watermelon planting of the substrate is greatly improved.

Description

technical field [0001] The invention relates to the technical field of nutrient substrates, in particular to a watermelon culture substrate with water hyacinth as the main raw material. Background technique [0002] Substrate cultivation is an important cultivation method in my country's current agriculture, forestry, and flower planting industries. It is a soilless cultivation method that absorbs nutrient solution and oxygen through the substrate. The advantages of saving water and fertilizer have been adopted and applied by the majority of planting producers. With the continuous development of my country's planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared from single raw materials such as peat and vermiculite or simply mixed can no longer meet the needs of planting. During the stage, the substrate generally has a single nutrient, resulting in low germination rate and...

At the same time, our country is rich in snake resources. Due to the clear and bright patterns on the appearance of snake skin and unique patterns, it is used to make various exquisite handicrafts. If 20-30% of snake skin is not effectively treated, it will not only pollute the environment, but also waste a lot of raw materials. Snake skin contains a lot of collagen, which also provides a cheap raw material basis for its application in matrix preparation.

[0004] The invention patent application with publication number CN1702061A discloses a kind of plant seedling raising and cultivation full nutrient substrate, and this nutrient substrate adopts the peat of 50-70% by weight, the perlite of 20-25%, the vermiculite of 10-15% and Active substances and nutrients are mixed, and have a relatively comprehensive nutrient composition. However, the cultivation substrate disclosed in the invention has different particle sizes, and it is easy to cause sedimentation after watering, resulting in blockage of the air in the substrate. At the same time, the crude fiber in the substrate The content is low, which requires the addition of additional nutrients, which increases the production cost, and does not increase the additional use value of the substrate according to the specific needs of cultivation, which limits the large-scale application of the product
