Embodiment 1

[0023] Drain the farmland and dry the field for 3 to 6 months. During the drying period, no crops are sown and the soil is turned over 2 to 3 times. Ridges are formed in the farmland to form the first strip-shaped ridge. The first ridge is filled with improved soil. The improved soil is obtained by mixing upland soil, peat soil, selenium-enriched mixture and fire fertilizer soil according to the weight ratio of 1:1:0.4:0.2~1.2:1:0.8:0.4. The paddy field soil that gets after month, fire fertilizer soil is straw, branches and leaves, fire ash that weeds burnt and woodland soil (forest land soil is preferably the forest soil of the pine forest in the west area of ​​Dabie Mountains or the slope soil of the hillside) according to 1: It is obtained by mixing and preparing at a weight ratio of 2 to 3; the selenium-rich mixture is obtained by composting and decomposing 4kg of green manure, 0.8kg of lime, 4.0kg of poultry manure, 0.5kg of cake fertilizer and 5-10g of sodium selenite; th...

[0028] Drain the farmland and dry the field for 3 to 6 months. During the drying period, no crops are sown and the soil is turned over 2 to 3 times. Ridges are formed in the farmland to form the first strip-shaped ridge. The first ridge is filled with improved soil. The improved soil is obtained by mixing upland soil, peat soil, selenium-enriched mixture and fire fertilizer soil according to the weight ratio of 1:1:0.4:0.2~1.2:1:0.8:0.4. The paddy field soil that gets after month, fire fertilizer soil is straw, branches and leaves, fire ash that weeds burnt and woodland soil (forest land soil is preferably the forest soil of the pine forest in the west area of ​​Dabie Mountains or the slope soil of the hillside) according to 1: It is obtained by mixing and preparing at a weight ratio of 2 to 3; the selenium-rich mixture is obtained by composting and decomposing 4kg of green manure, 0.8kg of lime, 4.0kg of poultry manure, 0.5kg of cake fertilizer and 5-10g of sodium selenite; th...

Embodiment 3

[0035] Dry field soil, peat soil, selenium-rich mixture and fire fertilizer soil are mixed and prepared according to the weight ratio of 1:1:0.4:0.2 to obtain improved soil. The dry field soil is the paddy field soil taken after the farmland was drained and dried for 6 months. No crops were sown during this period and the soil was turned over twice. The fire fertilizer soil was straw, branches and leaves, fire ash burned by weeds and forest land soil (preferably the forest soil of the Dabie Mountain pine forest or the slope soil of the hillside) according to the weight of 1:2 It is prepared by mixing; the selenium-rich mixture is 4kg green manure, 0.8kg lime, 4.0kg poultry manure, 0.5kg cake manure and 5g sodium selenite through composting and decomposing, and poultry manure adopts the following method to obtain: according to 6:3: Sorghum, wheat, and soybeans were ground and mixed at a mass ratio of 1 to prepare a fermentation substrate, yeast selenium was mixed with the fermen...

Abstract

The invention relates to a method for cultivating selenium-rich vegetables in improved farmland which is the method for planting osmunda japonica thunb in the farmland. The method specially comprises the steps that farmland drainage and field drying are conducted for 3-6 months, crops are not sown during field drying, the soil is turned twice or three times, a first ridge land is piled in the farmland, the first ridge land is formed by filling the improved soil, the improved soil is prepared by mixing dry farmland soil, peat soil, a selenium-rich mixed material and fire fat soil, a support is arranged by the side of the first ridge land, the support is provided with a water spraying pipe, and nozzles are arranged on the water spraying pipe at intervals; the osmunda japonica thunb is planted, seedlings are cultivated, and selenium-rich clay fertilizer application, irrigation and cultivation of the osmunda japonica thunb are achieved. According to the technical scheme, the yield and quality of the osmunda japonica thunb can be improved obviously, the osmunda japonica thunb can be picked every year after the third year, and the selenium content of the picked osmunda japonica thunb is high.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a method for improving farmland cultivation of selenium-enriched vegetables. Background technique [0002] Weicai, scientific name Ziji, is a perennial fern that exists widely in the Dabie Mountains. Oatmeal is rich in protein, vitamins, potassium, calcium, scale and other trace elements. Oatmeal can not only be made into delicious dishes, but also has the functions of anti-cancer, heat-clearing, detoxification, weight loss, and beauty. Viruses such as Japanese encephalitis have obvious inhibitory effect, and it is a long-term export and best-selling vegetable overseas, especially exported to Japan. [0003] At present, most of the weeds are collected in the wild. Although there are places where artificial planting is experimented, the yield is low. The collected weeds have thin stems and poor quality. After one or two years of picking, the weeds will die or no longer spro...
