Problems solved by technology

[0002] Before the present invention was proposed, the fertilizers used for rice seedling cultivation were ordinary farmyard manure and chemical fertilizers. Since the nutritional components were not comprehensive and the proportions were not reasonable, the rice seedlings bred were uneven, which directly affected the quality of rice seedlings. Slow seedlings after planting, while affecting the yield of rice

Embodiment Construction

[0006] According to the mass ratio, ammonium sulfate 30-40, monoammonium phosphate 20-30, potassium sulfate 20-30, zinc sulfate 5-8, calcium sulfate 5-8, humus 15-20, urea 5-10, ferrous sulfate 1 -2, 0.5-1.0 of boric acid, 1-2 of copper sulfate and 0.05-0.1 of S-inducer, after stirring and mixing, the special fertilizer for rice seedling raising of the present invention is made.

[0007] Among them, the humus is made of weathered coal, which is crushed into particles with a particle size of 0.1-0.5 mm.

[0008] Humus can also use humified biomass.

[0009] Effect

[0010] Tests have shown that the rice seedlings bred by the special fertilizer of the present invention grow 8.5 cm in root system than those bred by the same amount of constant chemical fertilizers, and the plant height increases by 5.3 cm. And the leaves are dark green, the leaves are straight, and the plants are strong.

Abstract

The invention provides fertilizer belonging to the agricultural field, especially a special fertilizer for seedling culture of paddy rice, which is prepared by stirring and mixing the following constituents by mass ratio: ammonium sulfate, monoammonium phosphate, lemery, zinc sulfate, calcium sulfate, humus, urea, green copperas, boric acid, bluestone and S-inducing and resisting element. The adoption of the special fertilizer for seedling culture of paddy rice to culture seedling can realize the purposes that the seedlings rapidly germinate and have strong and healthy seedling bodies, plant disease resistance and advanced root system, thus being in favor of rapid re-growth after transplanting. The fertilizer is suitable for being used as the fertilizer for paddy rice seedling culturing and other plants seedling.

Description

technical field [0001] The invention proposes a fertilizer in the field of agriculture, specifically a special fertilizer for rice seedling raising. Background technique [0002] Before the present invention was proposed, the fertilizers used for rice seedling cultivation were ordinary farmyard manure and chemical fertilizers. Since the nutritional components were not comprehensive and the proportions were not reasonable, the rice seedlings bred were uneven, which directly affected the quality of rice seedlings. Slow seedlings after planting will also affect the yield of rice. Contents of the invention [0003] In order to ensure that the fertilizer used for rice seedling cultivation has comprehensive nutrition and a moderate ratio, so that strong seedlings can be grown, the invention proposes a special fertilizer for rice seedling cultivation. The fertilizer is based on humic acid, and chemical fertilizers are added to solve the technical problem of rice seedling fertili...
