Description

A kind of cultivation method of selenium-enriched vegetables

technical field

The invention relates to the field of agricultural production, in particular to a method for cultivating selenium-enriched vegetables.

Background technique

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.

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 sprout.

Contents of the invention

The object of the present invention is to provide a cultivation method of selenium-enriched vegetables, which can effectively solve the above-mentioned problems. The yield of the weed is high, and the weed is strong and of good quality, and can be picked for a long time without yield reduction.

To achieve the above object, the present invention adopts the following technical solutions:

A method for cultivating selenium-enriched vegetables refers to a method for planting weed in hillside woodland, specifically comprising the following steps:

S1: The hillside forest land is prepared in a stepped manner, and the various planting sites after site preparation are set up along the contour line of the hillside. Ditch, the ditch is opened along the length of the planting field, and partitions are arranged at intervals along the length of the ditch. The partitions divide the ditch into various water tanks, and the first and second water outlets are respectively arranged on the two ends of each water tank. A third water outlet is provided on the tank wall outside the water tank. The height of the third water outlet on the same water tank is consistent with the height of the smaller water outlet among the first and second water outlets. The third water outlet on the adjacent water tank is in the shape of Arranged in a staggered interval, the top ditch of the hillside woodland is connected to the water supply device, and horizontally arranged water spray pipes are arranged on the outer side of the upper part of the dam ridge, and water spray holes/nozzles are arranged at intervals on the body of the water spray pipe. / The water outlet direction of the nozzle points obliquely to the side wall of the ridge. The water ditch divides the planting land into the first planting land located inside the ditch and the second planting land located outside the ditch. The first planting land is filled with improved soil The improved soil is prepared 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, and the upland soil is rice field drainage drying The paddy field soil was taken after 3-6 months, and the crops were not sown during the drying period, and the soil was turned 2-3 times. The fire fertilizer soil was straw, branches and leaves, and fire ash from burning weeds and woodland soil at a ratio of 1:2~ The weight ratio of 3 is mixed and prepared; the selenium-enriched mixture is obtained by composting and decomposing 4 kg of green manure, 0.8 kg of lime, 4.0 kg of livestock manure, 0.5 kg of cake fertilizer and 5-10 g of sodium selenite;

S2: In the spring of that year, 4 to 5-year-old thorn fir saplings were planted at intervals on the second planting ground. In the autumn of the same year, artificially propagated/wild weed seedlings were planted on the first planting site next to the bottom of the ridge at intervals, and water was poured in the ditch, and the water level in the ditch was lower than that of the first planting. The surface height of the ground is 12-17cm. Stop irrigation after frost and spread a layer of leaves on the surface of the first planting site;

S3: Irrigation starts after the second year of hiccups. Weet sprouts start to sprout from April to May. After sprouting, we turn on water spray holes/nozzles every night for 3-5 minutes of spraying/mist spraying. The first year of budding is not right. Picking, pruning the thorny fir tree, keeping one main branch, topping off the rest of the thorny fir seedlings to make the height between 1.4 and 1.6m, and sowing milk vetch and vetch on the first planting ground in the autumn of the second year. After the vetch matures, it is harvested and covered with the leaves on the surface of the first planting site, and the irrigation is stopped after the frost. From the second year, the selenium-rich soil fertilizer is sprinkled on the first planting site every year before the vetch and the leaves are covered. The amount of soil fertilizer is 120-150 kg per mu of the first planting land, and the selenium-rich soil fertilizer is 6 kg of green manure, 0.8 kg of lime, 4.0 kg of livestock manure, 3.5 kg of cake fertilizer and 3-5 g of sodium selenite through composting and decomposing ;

S4: From the third year onwards, repeat the following operations every year: start to irrigate after the sting of insects, and apply a budding fertilizer to the weed in March and April, and open the water spray hole/nozzle for 3-5 minutes every night after budding Spray/fog spray, pick vetch 3-4 times from April to May, trim the short branches of the thorny fir tree so that the height does not exceed 1.5m, sow milk vetch and milk vetch in the first planting place in autumn After maturity, it is harvested and covered with the leaves on the surface of the first planting site, and the irrigation is stopped after the frost, and the budding fertilizer is prepared by mixing fire fertilizer soil and human urine/urea;

The poultry and livestock manure is obtained by the following method: Sorghum, wheat, and soybean are pulverized and mixed according to the mass ratio of 6:3:1 to prepare the fermentation substrate, and the yeast selenium and the fermentation substrate are mixed evenly according to the mass ratio of 1:5, and water is added to the Fermentation treatment at 28°C for 70 days, the fermented product and feed are mixed for raising livestock and poultry, and the collected excrement of livestock and poultry is livestock manure.

The most important thing in the planting of weed is the control of water and fertilizer. Weir likes water and shade, but it is also afraid of waterlogging, and it is extremely harsh on the growing soil. In the present invention, through the transformation of the above-mentioned hillside forest land, the irrigation system composed of water ditches can make the water flow evenly irrigate the entire hillside forest land, and at the same time, the water level in the water ditch is controlled to be 12-17 cm lower than the surface of the first planting ground, so as to ensure the pleasing quality of weed. Water irrigation and no waterlogging will occur. Planting weed near the bottom of the ridge is far better than planting on flat ground. The influence of dam ridge makes the new stems and leaves grow away from the ridge, making its The phytohormone in the plant stimulates the roots to germinate more spores, increasing the yield. At the same time, the setting of the dam can make the water flow above the first planting site not flow from the surface of the first planting site, but penetrate into the ditch from the lower part, preventing In addition, the dam ridge built of stones can play a fixed role in the early stage of forest land transformation, preventing landslides during the rainy season from destroying the hillside forest land; water spray holes/nozzles are sprayed for a short time at night to simulate rainwater Every day, part of the rainwater is sprayed sparsely on the welt sprouts, which promotes the growth of the welt sprouts and makes the welt sprouts stronger; at the same time, the above-mentioned improved soil is more in line with the best requirements for the growth of welt in terms of acidity and fertilizer The coincidence makes the vetch stronger, and the vetch can grow luxuriantly on the soil of the first planting site. The harvested vetch and leaves are covered, so that the vetch can survive the winter better and ensure that the vetch will germinate next year. , the rot of milk vetch, leaves and the application of budding fertilizer can well supplement the fertility of the first planting site and adjust the acidity, so that the weed can be picked every year. The cost of propagation of the thorn fir tree is low, the survival rate is high, and the growth is fast. After the main branch is cut off, a large number of new seedlings will grow in the tree pocket, which can quickly form a shade fence around the welt, ensuring that the welt Vegetable growth environment needs, while shortening the cycle of the entire forest land transformation. Of course, the above is only a brief description of the main role played by each factor alone. Through the coordination of various factors, the Otto can be picked in high yield every year, and the Otto picked is strong and of good quality.

And adopt the above-mentioned improved soil and selenium-enriched soil fertilizer to carry out the planting of Oyster, the organic selenium can be effectively absorbed by the Oyster, which can effectively increase the selenium content in the Oyster, and the selenium content in the harvested dried Oyster is increased by about 3 to 4 times, composting Decomposition is exactly the method of green manure compost decomposing commonly used in agricultural production.

The detailed plan is:

The height of the ridge is 60-80cm, and the thickness of the improved soil filling is 30-35cm. A sand layer is arranged on the lower side of the improved soil filling layer, and the bottom of the ridge extends into the sand layer. After the second year, tea trees were planted on the second planting site. The tea trees were located inside the thorn fir trees and interlaced with the thorn fir trees. The bud-helping fertilizer is prepared by preparing 50kg of fire fertilizer soil and 10L of human urine. After the second year, the trunk of the thorn fir tree has become larger and the dwarf branches at the tree pockets are also luxuriant, forming a fence outside the ditch. At this time, larger tea saplings are planted inside it. Tea trees like shade. It can grow well. If tea trees are planted, the surface height of the second planting site can be set higher than the surface height of the first planting site, and multiple crops can be interplanted to improve the overall economic benefits. Moreover, thorny fir trees and weeds are crops that do not suffer from pests. Interplanting can eliminate the phenomenon that large areas of tea are prone to pests and diseases, and improve the economic benefits of the entire agriculture.

The above-mentioned technical scheme can significantly improve the yield and quality of the Osmunda, and the Osmanthus can be picked every year after the third year.

S2: plant interval on the ground at second kind spring then and to plant the thorn Chinese fir seedling of life in 4 ~ 5 years, after thorn China fir seedling survives, the trunk of thorn Chinese fir seedling is clipped and carried out preservative treatment to truncated position, the tree stump place tufted of thorn China fir grows thorn China fir seedling, in autumn in the same year the common vetch dish seedling of artificial propagation/wild planted at first kind and locate interval bottom the next-door neighbour ridge, dam on the ground and plant, and pour water in ditch, and water surface elevation in ditch is lower than the ground level 12 ~ 17cm of the first planting site, stop after the Frost's Descent irrigating and at earth's surface bedding one deck leaf of the first planting site;

S3: Second Year starts after the Waking of Insects (3rd solar term) to irrigate, 4 ~ May, common vetch dish started bract bud, what after bract bud, night every day opened that hole for water spraying/shower nozzle carries out 3 ~ 5min spreads spray/spray painting, bract bud First Year is not plucked common vetch dish, thorn Chinese fir is pruned, retain a major branch, all the other thorn China fir seedling carry out plucking top makes its height between 1.4 ~ 1.6m, plant at first kind in Second Year autumn and broadcast sowing Chinese milk vetch on the ground, cut after Chinese milk vetch maturation receive together with leaf bedding on the earth's surface of the first planting site, stop after the Frost's Descent irrigating, from Second Year, annual Chinese milk vetch and front the planting at first kind of leaf bedding spread fertilizer over the fields rich selenium clay fertilizer on the ground, the amount of spreading fertilizer over the fields of rich selenium clay fertilizer is that every mu of first planting site spreads fertilizer over the fields 120 ~ 150kg, rich selenium clay fertilizer is 6kg green manure, 0.8kg lime, 4.0kg poultry muck, 3.5kg cake fertilizer and 3 ~ 5g sodium selenite obtain through compost maturity,

S4: from the 3rd year, be repeated below operation every year: start after the Waking of Insects (3rd solar term) to irrigate, and 3, April applies once to help bud fertile to common vetch dish, what after bract bud, night every day opened that hole for water spraying/shower nozzle carries out 3 ~ 5min spreads spray/spray painting, 4 ~ May plucks 3 ~ 4 times common vetch dish, the dwarf branch bar of thorn Chinese fir is pruned, it is made highly to be no more than 1.5m, autumn broadcasts sowing Chinese milk vetch at the first planting site, cut after Chinese milk vetch maturation receive together with leaf bedding on the earth's surface of the first planting site, stop after the Frost's Descent irrigating, bud fertilizer is helped to obtain for fiery loam and people's retention of urine liquid/urea mixed preparing,

Poultry muck adopts following method to obtain: Chinese sorghum, wheat, soybean are pulverized according to the mass ratio of 6:3:1 and be hybridly prepared into fermentation substrate, according to the mass ratio of 1:5, yeast selenium and fermentation substrate are mixed, add water 28 DEG C of bottom fermentation process 70 days, the product of fermentation and feed are carried out being mixed for raising livestock and poultry, the feces of livestock and poultry of collection is poultry muck.

2. the cultivation method of rich selenium vegetables according to claim 1, is characterized in that: the height of Ba Geng is 60 ~ 80cm, and it is 30 ~ 35cm that improvement soil fills out whole thickness, and the downside that improvement soil fills out flood is provided with sandy soils, and dam extends in sandy soils bottom the ridge.

3. the cultivation method of rich selenium vegetables according to claim 1, is characterized in that: help bud fertilizer to prepare for 50kg fire loam and 10L people's retention of urine liquid and obtain.
