preparation example Construction
[0026] The method for preparing fermented cow dung according to the present invention preferably includes the following steps: after the cow dung is dried and pulverized, the water content is controlled to be 50-60%, and the pile is fermented. When the pile temperature reaches above 60°C, it is maintained for 24 hours, and then the pile is turned over. The fermentation is continued, and the pile is continuously turned 3 to 4 times to obtain the fermented cow dung. When the fermentation of the fermented cow dung of the present invention is completed, it is preferred that the material should be dark brown, odorless, and a large number of actinomycetes are produced, and the fermentation time is preferably 8-12 days.
[0027] The straw mushroom secondary species of the present invention is preferably a wheat grain secondary species, and the sowing rate of the straw mushroom secondary species is 400g / m 2 . The present invention does not have special limitation to the preparation m...
Embodiment 1
[0038] 1) Straw mushroom cultivation
[0039] 1. Cultivation season arrangement
[0040] Cultivated with strong alkali raw materials, straw mushrooms generally produce secondary wheat grains (400g) at the end of May, and agricultural waste (straw, corn stalks, corncobs, etc.) needs to be soaked in early June; sow in early July, and start harvesting in mid-July , harvested in mid-to-late August. When straw mushrooms are cultivated, the sheds are covered with 6-pin sunshade nets.
[0041] 2. Cow dung fermentation treatment method
[0042] Cow dung is dried in the sun and pulverized. During fermentation, water is added to make the water content reach 50-60%, and the pile is fermented. When the pile temperature reaches above 60°C, it is maintained for 24 hours, and then the pile is turned upside down and inside out to continue fermentation. This is carried out 3 to 4 times, until the material is dark brown, has no odor, and a large number of actinomycetes are produced, that is,...

Abstract
The invention provides a rotation cropping cultivation method of volvariella volvacea and alkali-land diospyros kaki in a greenhouse, and relates to the technical field of crop rotation cropping. The method comprises the steps that in the greenhouse, the volvariella volvacea is seeded in early July of every year, harvesting is completed in mid-to-late August, and mushroom bran is turned over into the ground; in March of the next year, solanum lycopersicum is cultivated, in late June, solanum lycopersicum stubbles are cleared up after harvesting is completed, 50-100 kg of lime is spread into the land per mu, ploughing is carried out, and 15 days after the greenhouse is closed, cultivation of the volvariella volvacea is prepared. The rotation cropping cultivation method of the volvariella volvacea and alkali-land diospyros kaki in the greenhouse has the advantages that while the economic benefit is obtained from harvesting of the volvariella volvacea, the mushroom bran after volvariella volvacea cultivation and degradation returns to the field in situ, which increases the soil fertility, reduces the application rate of organic fertilizers for alkali-land diospyros kaki planting and reduces the planting cost. A singly planted alkali-land diospyros kaki planting mode is compared with a 'volvariella volvacea and alkali-land diospyros kaki rotation cropping' planting mode, the income is increased by at least18,000 yuan per mu, and the volvariella volvacea mushroom bran returns to the field so that the input fertilizer expense can be reduced by 1,500 yuan per mu.
Description
technical field [0001] The invention belongs to the field of crop rotation techniques, and in particular relates to a cultivation method for crop rotation of straw mushrooms and persimmons on alkaline land in a shed. Background technique [0002] The distribution of saline soil in the Songnen Plain in my country is very extensive, and the total area of saline soil is about 3.42 million hm 2 , is one of the world's three largest concentrated distribution areas of soda saline soil. The Daqing area of Heilongjiang Province is located in the hinterland of the Songnen Plain, and the total area of salinization reaches 429955hm 2 , can grow alkaline persimmons on a large scale. Alkaline persimmon grows on saline-alkali soil. It has a strong taste, greenish color, thick flesh, sweet taste, juicy and refreshing taste, and excellent flavor. The content of vitamin A and C is 3.7 times that of ordinary persimmons, and the market price is high. However, the yield of persimmons ...
