Problems solved by technology

[0004] The amount of fertilizer required for vegetable seedlings is relatively small, the amount of compound fertilizer or chemical fertilizer added to the substrate is small, and the uniformity of mixing is not suitable for control. Improper operation may easily cause burnt seedlings or insufficient nutrition of seedlings, seriously affecting the quality of seedlings, and even causing greater losses
At present, there is no relevant research report on the uniform mixing of substrate and fertilizer.

Embodiment Construction

[0048] In this example, peat is used as the main material, vermiculite and perlite are auxiliary materials, and a conventional preparation volume ratio of 3:1:1 is used to prepare a nutrient matrix that can meet the growth needs of cabbage seedlings (4 leaves and 1 core at seedling age) and provide stable 1. A method for batch production of cabbage seedling raising substrates.

[0049] Quality requirements for cabbage seedling substrate:

[0050] 1. A nutritional substrate that meets the growth needs of cabbage seedlings (4 leaves and 1 heart at seedling age);

[0051] 2. Hydrolyzable N and P in the cabbage seedling substrate (dry weight) 2 o 5 、K 2 The total content of O is 4.7g / kg, and the ratio is 1:2.6:3.1;

[0052] 3. The fertilizer mixing method is to dissolve the fertilizer in water and then spray it into the substrate, using a stirring speed of 30 rpm, stirring for 2 minutes, and mixing evenly.

[0053] 4. When the matrix is ​​mixed, use 5-point sampling to measur...

Abstract

The invention discloses a cabbage seedling raising substrate and a preparation method thereof. In the dry weight of the cabbage seedling substrate, the total content of hydrolyzable N, P2O5 and K2O was 4.7g / kg and the ratio was 1:2.6:3.1. The invention satisfies the quick-acting nitrogen, phosphorus and potassium nutrient content and appropriate ratio of the substrate when the cabbage seedlings grow to the stage of 4 leaves and 1 heart, the cabbage seedling cultivation substrate is rich in nutrients, the fertility is stable and lasting, and no chemical fertilizer needs to be supplemented during the cultivation period. Compared with the same substrate: the root number of cabbage seedlings at 4 leaves and 1 heart stage increased by 21.4%, root dry weight increased by 19.6%, ground dry weight increased by 28.8%, and the incidence rate decreased by 33.1%.

Description

technical field [0001] The invention relates to a cabbage seedling raising substrate and a preparation method thereof. Background technique [0002] Substrate seedling cultivation and conventional nutrient soil cultivation have the advantages of saving energy and resources, reducing the cost of seedling cultivation; well-developed root system, fast seedling growth, high survival rate; suitable for long-distance transportation and mechanized transplanting and many other advantages. Substrate is the basic condition for growing seedlings in plug trays. It has the functions of fixing crop roots, providing root water and nutrients, and coordinating the contradiction between water and air, which directly affects the quality of seedlings. At present, industrial seedlings in my country mostly use a composite matrix made of peat, vermiculite and perlite mixed in different proportions; however, the nutrient content of peat, vermiculite and perlite is extremely low, and nutrient soluti...
