Special functional base material for nutrient-solution-free soilless seedling cultivation of cucumbers and preparation method of special functional base material

Abstract

The invention relates to a preparation method of a special functional base material for nutrient-solution-free soilless seedling cultivation of cucumbers. The special functional base material can be used for effectively simplifying water and fertilizer management of the soilless seedling cultivation of the cucumbers, and improving the compound type of seedling quality, and a multifunctional nutrient-solution-free soilless seedling cultivation base material formula is obtained. Mushroom dregs are used for partially replacing turf to prepare a soilless seedling cultivation optimized formula base material of the cucumbers; the special functional base material for the nutrient-solution-free soilless seedling cultivation is formed by adding functional substances including a controlled-release fertilizer, a chemical fertilizer, chitosan and the like according to the nutrient content of the base material and the nutrient requirements in a seedling period of the cucumbers; the fertilizer supplying performance of the base material is improved and the nutrient solution management is not carried out in the whole process; the growth of seedlings is promoted and the resilience capability is enhanced. Compared with a current usually-used turf-vermiculite soilless seedling cultivation base material formula, the preparation method has the advantages of reducing the investment of resources, simplifying the seedling cultivation management, cultivating high-quality strong seedlings and the like, and has the environment-friendly and pollution-free effects.

Description

(1) Technical field [0001] The invention relates to a special functional substrate for cultivating cucumbers with nutrient-free solution and soilless seedlings and a preparation method thereof, belonging to the field of agricultural high-tech. (2) Technical background [0002] Since 2008, vegetable intensive soilless seedling cultivation technology represented by plug seedling cultivation has been promoted nationwide as the main technology promoted by the Ministry of Agriculture. Vegetable seedling cultivation is becoming a new and very dynamic industry, gradually becoming large-scale and professional. development and modernization. [0003] At present, soilless seedlings usually use a composite matrix composed of peat, vermiculite, perlite, etc. Although peat is an ideal substrate for raising seedlings, its resources are limited and cannot be regenerated in a short period of time. Excessive exploitation will cause depletion and damage the ecological environment. Moreover,...

AI Technical Summary

Problems solved by technology

Although peat is an ideal seedling substrate, its resources are limited and cannot be regenerated in a short period of time. Excessive exploitation will cause depletion and damage the ecological environment.

Moreover, due to the small hole volume, weak buffering performance, and weak fertilizer and water retention capacity of plug seedlings, the nutrient solution needs to be irrigated frequently. The preparation and management of the nutrient solution are cumbersome, and the technical requirements are high. loss, which not only reduces resource utilization efficiency, but also pollutes the environment

In addition, the above-ground and underground space of plug seedlings is limited, and the seedlings often grow excessively due to competitive growth in the later stage of growth, which affects the formation of strong seedlings
