Preparation method of nursery site medium for planting organic vegetable

Abstract

The invention provides a preparation method of a nursery site medium for planting organic vegetable. The preparation method comprises the following steps: preparing materials (saw dust, cattle manure, duck manure, floating aquatic plant powder, corn cob crushed matter, perlite, vermiculite, plant ash, mulberry leaves, radix phytolaccae, toosendan fruit, garlic powder, sodium alginate, BFA, indolebutyric acid, sodium carboxymethyl starch, 12wt% sodium chloride aquatic solution and fine earth); A, fermenting the raw materials: uniformly mixing the saw dust, the cattle manure, the duck manure, the floating aquatic plant powder, the corn cob crushed matter and the fine earth, controlling the moisture content to be 57-62%, and adding the corrosion promoter; B, preparing a traditional Chinese medicine extraction liquid; C, preparing a plant ash leach liquor by use of the plant ash; D, adding the sodium alginate, the BFA, indolebutyric acid and sodium carboxymethyl starch into the 12wt% sodium chloride aquatic solution; E, soaking the vermiculite in the traditional Chinese medicine extraction liquid; F, mixing the fermented material obtained in the step A, the perlite soaked in the step D and the vermiculite soaked in the step E at a ratio of 8:1:1. The preparation method is simple in proportion, convenient to use, good in nursing effect, developed in seedling root, good in water retention property and rich in nutrients.

Description

[0001] Technical field: [0002] The invention relates to the technical field of agriculture, in particular to a method for preparing a seedling tray substrate for planting organic vegetables. [0003] Background technique: [0004] At present, peat, rock wool, vermiculite, perlite, bagasse, mushroom dregs, gravel and ceramsite are the most commonly used matrix materials for greenhouse seedling cultivation. At present, rock wool and peat are the most widely used in the world, and are recognized as ideal cultivation substrates in the world. However, with the large-scale use year by year, its negative effects on society and the ecological environment are becoming more and more obvious. On the one hand, because rock wool is not degradable, extensive use will cause secondary pollution to the environment; on the other hand, peat is a non-renewable resource. , Excessive mining has the risk of depletion; therefore, seeking and discovering an excellent new seedling substrate that ...
