Embodiment 1

[0036] 1. The rice husk base flue-cured tobacco floating seedling raising substrate of the present embodiment, its preparation steps are as follows:

[0037] ⑴, rice husk pretreatment:

[0038] ①. Pile up: first moisten the rice husk with water until the water content reaches 62%, then add urea according to the weight of 0.2% of the raw material of the rice husk, mix well, and pile up into a strip-shaped pile with a height of 1.8 meters and a width of 2 meters. Then cover the strip pile with plastic film;

[0039] ②, initial cover pile: cover the long strip pile covered with plastic film for 25-30 days, during the cover pile period, turn the pile every 10 days; replenish water in time when turning the pile, and keep the moisture content up to 62%; When the color of the rice husk turns brown, the outer shell becomes soft, it cannot be crushed by hand, and the rice husk is in flake shape, at this time, the decomposition of the grain and the chaff is completed, and the heaping i...

Embodiment 2

[0055] 1. The rice husk base flue-cured tobacco floating seedling raising substrate of the present embodiment, its preparation steps are as follows:

[0056] (1), rice husk pretreatment: same as embodiment one;

[0057] ⑵, material preparation: take respectively by volume:

[0058] 50 parts of rice husk treatment material, 32 parts of perlite, 16 parts of vermiculite, 2 parts of fine sand, set aside;

[0059] ⑶, initial mixing: mix the above-mentioned spare raw materials evenly, become the initial mixing material, and set aside;

[0060] ⑷, compound mixing: add nitrogen, phosphorus and potassium fertilizers to the spare primary mixture, so that the total content of nitrogen, phosphorus and potassium reaches 240mg / kg; among them: the nitrogen content reaches 80mg / kg, the phosphorus content reaches 80mg / kg, and the potassium content reaches 80mg / kg; mix uniformly, and become the rice husk base flue-cured tobacco floating seedling raising substrate of the present invention.

Abstract

The invention discloses a rice hull based floatation seedling nursing matrix for flue-cured tobacco and a supporting seedling nursing nutrient solution thereof and relates to the field of flue-cured tobacco seedling nursing technologies of agricultural techniques. The rice hull based floatation seedling nursing matrix for the flue-cured tobacco is prepared from the following raw materials in parts by volume: 45-50 parts of rice hull treated material, 30-35 parts of pearlite, 16-20 parts of vermiculite and 2 parts of fine sand. The seedling nursing nutrient solution is prepared from the following raw materials in parts by weight: 30-60 parts of calcium nitrate tetrahydrate, 300-350 parts of ammonium nitrate phosphate, 360-400 parts of potassium nitrate, 40-80 parts of magnesium sulfate heptahydrate, 150-200 parts of monoammonium phosphate, 5-10 parts of DA-6, 10-20 parts of zinc sulfate heptahydrate, 10-20 parts of sodium citrate, 10-25 parts of boric acid, 10-20 parts of chalcanthite and 1,000,000 parts of water. The rice hull based floatation seedling nursing matrix for the flue-cured tobacco and the supporting seedling nursing nutrient solution thereof have the characteristics that the consumption of grass charcoal can be reduced, the seedling nursing cost is reduced, healthy and strong tobacco seedlings can be cultured and the like and are applicable to the floatation seedling nursing of the flue-cured tobacco of all flue-cured tobacco planting areas across the country.

Description

technical field [0001] The invention relates to the flue-cured tobacco seedling raising technology in the field of agricultural technology, in particular to a rice husk-based flue-cured tobacco floating seedling raising substrate and a matching seedling raising nutrient solution. Background technique [0002] Floating seedling cultivation is a method of cultivating seedlings without soil. It is a new form of factory production. Its biggest advantage is that it can produce sufficient, uniform, uniform, and strong seedlings without pests and diseases. It can grow early and quickly, and grow neatly and uniformly. Significantly improve the level of large-scale production, and because it is raised in a clean environment, no pests and diseases will be brought to the field. Therefore, since 2000, floating seedlings have been gradually promoted in tobacco seedlings across the country. So far, floating seedlings account for more than 70% of the entire tobacco seedlings, and 0.07 cubi...
