Method for interplanting stropharia rugosannulata in vineyard

InactiveCN102972209AHorticultureHumusMulch
The invention discloses a method for interplanting stropharia rugosannulata in a vineyard. The method comprises the following steps of scarifying soil and drying the soil in the sun before seeding, so that the soil is cured and loosened; seeding at a temperature between 8 DEG C. and 30 DEG C.; soaking straws for 35 6 hours; soaking wheat straws, cornstalks and bean stalks for 48 hours; pre-stacking cultivation materials, wherein the stack width is 2 m, and the stack height is 1.5 m; turning the stacks after three days, and turning the stacks again after another two to three days; seeding when the water content is 75%; first spreading a humus soil layer which is 4-5 cm in thickness when seeding; forming a turtleback ridge-up bed which is 30 cm in height and 1.3 m in width, wherein sidewalks of 40 cm in width are left among the ridges, and a first spreading on the ridges is 8-10 cm in thickness; seeding 50% of strains; not spraying water on the stropharia rugosannulata bed within 20 days after seeding, but spraying on coverings; controlling the temperature of the cultivation materials at 20-30 DEG C.; uncovering films for ventilation when the temperature is higher than 30 DEG C. and spraying water on the coverings for cooling; and covering the ridges with mats or films when the temperature is below 20 DEG C., wherein the relative humidity on the ridge surface is between 90% and 95%; and the preferenpreferencetial temperature for fruiting is 14 to 25 DEG C.

Light-weight reinforced gypsum plaster board and preparation method thereof

ActiveCN104478382AImprove moisture bonding qualitySolve the problem of low grade and low strengthSolid waste managementCeramicwareCelluloseFiber
The invention relates to a light-weight reinforced gypsum plaster board and a preparation method thereof. The light-weight reinforced gypsum plaster board is prepared from the following raw materials in parts by weight: 100 parts of a gypsum clinker, 0.1-1 part of modified starch, 0.01-0.1 part of a foaming agent, 2-10 parts of rice straw fiber powder, 0.1-0.6 part of CMC (carboxyl methy cellulose) powder and 50-100 parts of water. By adding the rice straw fiber powder and the CMC powder, the workability of slurry is improved, the problems of low grade and low strength of desulfurization gypsum are solved, and particularly the rice straw fiber powder has an adsorption effect on Cl, so that the wetting bond quality of the gypsum plaster board is greatly improved; meanwhile, the consumption of the desulfurization gypsum and the foaming agent is reduced, and the strength and bond performance of the board are improved; the prepared gypsum plaster board is good in wetting bond performance, the mass per unit area of a 9.5mm waterproof board is 6.4kg/m<2> which is far superior to a national standard requirement that the mass per unit area is not less than 9.5kg/m<2>; and the average value of the transverse breaking load is 216.5N, the minimum value of the transverse breaking load is 202.6, the average value of the longitudinal breaking load is 448.0N, the minimum value of the longitudinal breaking load is 423.8N, and the strength is far higher than a national standard requirement.
