Embodiment 1

[0018] The method for preparing the substrate of the southern yew container seedlings firstly prepares decomposed vinegar grains, and initially turns the fresh vinegar grains to dry, and adds EM bacterial agent when the moisture content reaches 60% to 70%, and then composts and ferments after mixing. Turn over every 3 to 5 days. From the 20th day of fermentation, samples were taken every 3 to 5 days to determine the germination index (GI). Specifically, the extract was obtained by extracting the fermented product at a ratio of 1:10 per unit dry weight to deionized water, and was measured by conventional GI measurement methods. The test seeds used were Shanghai Qing seeds. When the germination index reaches 85% on the 30th day of fermentation, it means that the fermentation is mature.

[0019] EM bacterial agent is purchased from the market, and the addition amount is 0.8-1.2kg per cubic meter of fresh vinegar grains;

Embodiment 2

[0029] The preparation method of the substrate of the southern yew container seedlings, first prepares the decomposed vinegar grains, and the fresh vinegar grains are initially turned over to dry, and when the moisture content reaches 60% to 70%, the composting is naturally fermented, and the fermentation process is carried out every 3 to 5 days. Turn over once. From the 20th day of fermentation, samples were taken every 3 to 5 days to determine the germination index (GI). Specifically, the extract was obtained by extracting the fermented product at a ratio of 1:10 per unit dry weight to deionized water, and was measured by conventional GI measurement methods. The test seeds used were Shanghai Qing seeds. On the 39th day of fermentation, the germination index reached 87%, indicating that the fermentation was mature.

[0030] Then prepare the primary decomposed vinegar grains and primary decomposed sawdust:

[0031] Preparation of preliminary decomposed vinegar grains: Turn o...

Abstract

The invention discloses a southern yew container seedling substrate, which is formed by adding decomposed vinegar grains to fresh vinegar grains and sawdust, adding urea to the sawdust, performing primary fermentation, adding perlite after mixing, and performing secondary fermentation. The bulk density of the prepared matrix is ​​0.40±0.02g / cm 3 , the total porosity is 62.8±2.2%, the water-holding porosity is 38.8±1.1%, and the air porosity is 24.0±1.3%. A preparation method thereof is also disclosed. The matrix of the present invention is mainly prepared from vinegar grains and sawdust organic waste, and the preparation process is simple and easy to operate; the raw materials involved are mainly fermented organic waste products, and the amount of bacterial agent used is greatly reduced, which reduces the production cost , and at the same time realize the comprehensive utilization of waste resources and reduce environmental pollution. The prepared matrix not only has a good seedling raising effect, but also can replace the conventional peat matrix, with low cost and broad market prospects; the matrix prepared according to the preparation method can significantly increase the plant height, ground diameter and total branch number of the southern yew container seedlings, and improve the leaf quality. Chlorophyll content.

Description

technical field [0001] The invention relates to a southern yew container seedling substrate and a preparation method thereof. Background technique [0002] Southern yew is one of the unique yew varieties in my country. Due to its combination of medicinal, material and ornamental purposes, the southern yew is also known as "plant gold", and it is a rare and endangered tree species in the world. And the southern yew is fast-growing in the early stage and has high biological yield, so it has great development and utilization value. But southern yew plant resources are scarce and difficult to cultivate, which has become the key to restrict the development of yew plantation and the sustainable utilization of resources. In the past 20 years, container seedling cultivation technology has been widely used in order to solve the problems of low emergence rate and survival rate and long cultivation cycle of yew in traditional field cultivation of yew. However, the substrate used for...
