Special nutrient matrix for replacement of oily sha bean plowing layer

Abstract

The invention discloses a special nutrition medium for displacement of a mandulapalka plough layer. The special nutrition medium is prepared by the method comprising the following steps: 1, compounding a special strain through EM bacterium and free-living nitrogen fixing bacteria in a active bacteria number ratio of 1: 1; uniformly mixing the special strain, bran and water in weight ratio of 1: (15-20): (14-18); shading and standing for 24 hours to obtain mixed strains; 2, mixing the mixed strains with dry rice husk in a weight ratio of 1: (300-500); adding water, uniformly agitating; composting for 7 to 10 days in a moist state; and drying by the air to obtain the special nutrition medium for displacement of the mandulapalka plough layer. The special nutrition medium for displacement of the mandulapalka plough layer, prepared by the method can solve the problem of difficult harvesting of mandulapalka; necessary nutritional components can be provided to mandulapalka for growth; the soil condition can be improved; the mandulapalka can grow well; and after harvesting the mandulapalka, the medium residue in the soil can improve soil and increase fertility of the soil.

Description

technical field [0001] The invention relates to a nutrient matrix, in particular to a special nutrient matrix for the replacement of the plowing layer of oily sand bean, and belongs to the field of agricultural technology. Background technique [0002] The origin of oily bean is Africa, and it is an annual plant of the Gramineae family, with strong adaptability. Later it was introduced and planted in China. It is a high-quality, high-yielding, high-value multi-purpose new crop for oil and grain, also known as Shan sedge, and is also an ornamental plant for beautifying and greening the environment. This variety has strong adaptability and high yield. Generally, the yield per mu is 1000Kg of fresh beans and 500kg of dry beans, and 1 mu of oily beans is equivalent to 7-10 mu of rapeseed. The needle-shaped leaves are thin and long, and the plant height is about 1 meter. It grows vigorously, has strong tillering ability, and knots underground. The fruit is oval, and the oil yi...

Problems solved by technology

The tubers of Yousha bean are small, with a thousand-grain weight of about 260 to 650 grams. It takes 3 workers to sow (on-demand) an acre, and 30 workers to harvest an acre. The cost is relatively high, and the cost of large-scale planting is more prominent.
