Problems solved by technology

At present, the cost of commercialized eggplant seedling substrates is relatively high, and peat-based commercial substrates are mostly used. In order to ensure the growth of eggplant seedlings, it is necessary to add fertilizers to the seedling cultivation substrates or spray fertilizers with water during the growth period of eggplant seedlings to ensure the growth of eggplant seedlings. seedling growth, but this not only increases the cost and is easy to make the eggplant seedlings grow excessively, which is not conducive to the cultivation of strong seedlings, but also has many disadvantages to the growth of eggplant seedlings
[0004] Applying fertilizers to meet the nutritional needs of eggplant seedlings may, on the one hand, increase the soluble salt content in the cultivation medium (that is, increase the electrical conductivity), which may easily cause the eggplant seedlings to suffer from salt damage and affect growth.
Moreover, after fertilizers are applied, due to nitrogen mineralization and nitrification, the pH value of the substrate will fluctuate greatly, which is not conducive to the growth of eggplant seedlings in the early stage.
In addition, if the amount of fertilizer is not appropriate, it will damage the young roots of eggplant seedlings, which is not good for the growth of eggplant seedlings in the later stage.
At the same time, if there is too much fertilizer, it will easily cause the eggplant seedlings to grow excessively, which is not conducive to the robustness of the eggplant seedlings, and will affect the high yield and harvest of eggplant in the later period.

Embodiment 1

[0039] The present embodiment provides a kind of preparation method that is used for the nutrient soil of eggplant seedling raising, and described method is carried out according to the following steps:

[0040] a. Material preparation:

[0041] Mix the prepared fresh cow dung well, cover it with film and pile it up for fermentation. When the temperature reaches 60°C, turn it over and keep it within the temperature range for 5 days. During this period, turn it twice until the material turns dark brown and the temperature reaches 25°C When it is dried, crushed and set aside;

[0042] Add 0.1% of the commercially available bio-organic decomposing agent to the prepared paddy rice husk and chicken manure, mix well, and then pile up and ferment. When the temperature reaches 60°C, turn the pile and keep it in this temperature range for 14 days , turned over 7 times during the period, when the temperature of rice husk and chicken manure reached 25°C, and when the water content was red...

Embodiment 2

[0052] a. Material preparation:

[0053] Mix the prepared fresh cow dung well, cover it with film and pile it up for fermentation. When the temperature reaches 50°C, turn it over and keep it within the temperature range for 7 days. During this period, turn it twice until the material turns dark brown and the temperature reaches 30°C when, standby;

[0054] Add 0.5% of the commercially available bio-organic decomposing agent to the prepared paddy rice husk and chicken manure, mix well, and then pile up and ferment. When the temperature reaches 50°C, turn the pile and keep it in this temperature range for 21 days , turned over 12 times during the period, when the temperature of the rice husk and chicken manure reached 35°C and the moisture content was reduced to 30%, it was ready for use;

[0055] Mix the prepared soybean meal well, cover it with film and pile it up, then ferment it, and set it aside; the fermentation method is the common soybean meal fermentation method, the f...

Embodiment 3

[0064] a. Material preparation:

[0065] Mix the prepared fresh cow dung well, cover it with film and pile it up for fermentation. When the temperature reaches 55°C, turn it over and keep it within the temperature range for 6 days. During this period, turn it twice until the material turns dark brown and the temperature reaches 26°C when, standby;

[0066] Add 0.3% of the commercially available bio-organic decomposing agent to the prepared paddy rice husk and chicken manure, mix well, and then pile up and ferment. When the temperature reaches 55°C, turn the pile and keep it in this temperature range for 17 days , turned over 10 times during the period, when the temperature of the rice husk and chicken manure reached 30°C and the moisture content was reduced to 25%, it was ready for use;

Abstract

The invention provides nutritional soil for cultivating eggplant seedlings and a preparation method of the nutritional soil. The preparation method comprises the following steps: firstly, selecting fermented cow dung, fermented rice husk chicken manure and composted pleurotus ostreatus residues and other raw materials which are commonly used in daily production according to growth demands of the eggplant seedling stage; secondly, preparing special nutritional soil for cultivating the eggplant seedlings by multiple formulation screening experiments. The nutritional soil is economical and practical as well as is beneficial to growth of the eggplant seedlings; in addition, during the seedling cultivation period for two months or longer, spraying of fertilizer is not needed, and the eggplant seedlings vigorously grow; the nutritional soil is a better choice for cultivating the eggplant seedlings. At present, generally-applied cultivation matrixes in the world are peat and rock wool, but the two matrixes are expensive, peat resources are unrenewable, and the rock wool is non-degradable, therefore, all countries in the world are trying to study substitutes of the peat and the rock wool. At the same time, the fermented cow dung, the fermented rice husk chicken manure, the composted pleurotus ostreatus residues and the like are used, so livestock manure and agricultural wastes are enabled to be recycled, and replace the non-renewable peat, and further resource conservation and environment friendliness are facilitated.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a nutrient soil for raising eggplant seedlings and a preparation method thereof. Background technique [0002] Eggplant is the third largest vegetable species of Solanaceae after tomato and potato, and it is widely planted all over the world. According to FAO statistics, the total harvested area of ​​eggplant in my country in 2014 was 803,600 m 2 , the total output is 29.5268 million tons, the total area and total output accounted for 42.96% and 58.77% of the world respectively. [0003] At present, the eggplant cultivation mode is early spring cultivation, autumn delayed cultivation, etc. The age of eggplant seedlings is relatively long, and it takes about 50 to 70 days from sowing to seedlings, so seedling cultivation and transplanting are mostly used. In particular, eggplants are cultivated in early spring in large arch sheds, because most of them are planted in early M...
