The invention discloses a cottonseed husk package for mushroom planting which can be used repeatedly, which comprises a rotating shaft chassis, a rotating shaft column is movably connected in the middle of the rotating shaft chassis, a cultivation plate is sleeved on the rotating shaft column, and the bottom end of the cultivating plate is connected with the rotating shaft column. The connection is fixedly connected with a damping rubber ring, a ring of placement grooves is set at the center of the culture plate, and ventilation grooves are set between the culture plates; the design of the device through the multi-layer culture layer greatly improves the space utilization rate and improves the The number of bacteria produced; the device places cottonseed husk bags in a separate small space, reducing the labor of manpower handling and turning over, and facilitating the tedious operations of operators; the device is convenient for controlling the ventilation rate and for repeated use. save costs.

The invention discloses a method for rapidly repairing a south metal tailing sand reservoir by using lespedeza container seedlings. The method comprises the following steps: (1) drying lespedeza seeds collected in the diggings, cultivating the seedlings in a greenhouse in the first and middle ten-day of March; (2) while the seedlings are grown to 12-15 cm, transplanting the seedlings to a new non-woven fabric container, and adjusting a soil matrix according to the tailing sand soil fertility feature and the moisture and fertilizer retention capability; (3) selecting the strong lespedeza non-woven fabric container seedlings with a developed root system in the middle and last ten-day of May, transplanting by using a method that the planting is carried out while the hole is digged, and digging the hole and planting according to 1 m X 1m of the line spacing; (4) after planting the lespedeza, uniformly stirring the soaked grass seeds of grass family and a calcium magnesium phosphate fertilizer of nitrogen and phosphorus, and broadcast-sowing between the rows; and (5) dressing a nitrogen fertilizer in 4 mg / mu every year. After two years of a curing period, the lespedeza is grown well, the tailing sand is covered by dead leaves, and trees and shrubs suitable for the tailing sand site conditions can be planted, so the metal tailing sand reservoir is repaired by planting the repair plants. The method is suitable for repairing the south uncovered metal tailing sand reservoir.
