A compound substrate of organic waste suitable for protected cultivation of small watermelons

Abstract

The invention discloses an organic waste compound substrate suitable for facility cultivation of small watermelons. The organic waste composite matrix is ​​formed by mixing M1 components and M2 components; wherein, the M1 component is composed of coconut peat and vermicompost, and the M2 component is composed of decomposed cassava skin and bagasse fire charcoal ash. On the premise of ensuring good growth and increased yield of small watermelons, the present invention uses common and easily available agricultural and forestry wastes in South China as the main raw material compounding, has good physical and chemical properties, and is completely suitable for the water and nutrient requirements of small watermelon facility cultivation. It can promote the growth of plants and roots of small watermelons, increase the single fruit weight of small watermelons, increase the nutritional content of small watermelons, and obtain ideal yield and fruit quality; at the same time, it has a strong ability to hold water and fertilizer, which can effectively reduce substrate costs and save water and energy. Fertilizer, while realizing cost savings and efficiency increase, is also conducive to the recycling of waste resources, and has good promotion value.

Description

technical field [0001] The invention belongs to the technical field of small watermelon protected cultivation. More specifically, it relates to a compound substrate of organic waste suitable for facility cultivation of small-scale watermelons. Background technique [0002] Small watermelon (Citrullus lanatus Matsum.et Nakai) is a vine of Cucurbitaceae (Cucurbitaceae), also known as gift watermelon and high-quality watermelon. , because of its small and beautiful fruit shape, tender flesh, juicy and sweet taste, and easy to carry, it is favored by consumers. It is one of the fruit varieties with high economic benefits and large cultivation volume in modern greenhouses and facility agriculture. [0003] Facility substrate cultivation is an important way to produce small watermelons, and choosing a suitable cultivation substrate is crucial to ensure the yield and quality of small watermelons. The small-scale watermelon facility culture matrix formula that has been reported at...

AI Technical Summary

Problems solved by technology

The above research results have a certain reference value for the production of small watermelons, but there are still deficiencies, such as peat, coconut peat and other high-cost commodity substrates account for a relatively high proportion, resulting in high substrate costs; no water and fertilizer management facilities are involved Measures or water and fertilizer management are relatively extensive, which is likely to cause waste of resources, etc.
