Embodiment 1

[0029] A method for raising organic rice stubble ducks in a low-humidity saline-alkali land, carried out according to the following steps:

[0030] A. Use deep plowing to plow and level the soil. The plowing depth is 20-30cm. Add water until the water surface is 2cm higher than the soil surface. Soak the field for 6 days;

[0031] B, discharge the stagnant water in the field, sprinkle calcium superphosphate and microbial fertilizer in the field, plow again, level off, add water, the water surface is 12cm higher than the soil surface, insert rice seedlings, throw in earthworms and ducklings, and put the ducklings in The time is: 20 days after hatching, the weight of ducklings is about 100 grams or more, 15 days for throwing rice seedlings, and more than 12 days for transplanting, and then they can be put into the field;

[0032] C, spray photosynthetic bacteria on the leaves every 13 days in the initial stage of rice growth;

[0033] D. Microbial fertilizers and earthworms nee...

Abstract

The invention provides a method for feeding organic rice-ducks on a low-humidity saline-alkaline land. A pH value of soil is improved by cooperation of microbial fertilizer and calcium superphosphate, the fertilizer is provided for the growth of rice, and meanwhile, newly-hatched ducklings and earthworms are put in, so that the improvement speed of the saline-alkaline land can be increased, the rice yield is increased year by year, and the improvement of the saline-alkaline land can be basically completed after 2-3 years.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for raising organic rice stubble ducks in low-humidity saline-alkali land. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkalized so...
