A kind of planting method of selenium-enriched tea leaves to prevent pests

technical field

The invention relates to the field of agricultural production, in particular to a method for planting selenium-enriched tea to prevent pests.

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 planting method of selenium-enriched tea leaves to prevent pests, which can effectively solve the above problems. The yield of the Osmanthus is high, and the Osmanthus is strong and of good quality, and can be picked for a long time without reducing production.

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

A method for planting selenium-enriched tea leaves to prevent insect pests refers to a method for interplanting weed, tea leaves, and thorn fir in a hillside woodland, and specifically includes 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 groove wall outside the water tank, and 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 water outlets are arranged in a staggered manner at intervals. The top ditch of the hillside woodland is connected to the water supply device. The upper and outer sides of the dam ridge are provided with horizontally arranged water spray pipes. One water outlet direction of the two-way nozzle points obliquely to the side wall of the dam ridge, and the other water outlet direction of the two-way nozzle points obliquely downward to the side wall away from the dam ridge. The second planting site on the outside of the ditch, the first planting site is filled with improved soil, and the improved soil is mixed with upland soil, peat soil and fire fertilizer soil according to the weight ratio of 0.5:1:0.2～0.8:1:0.4 Obtained, the dry field soil is the paddy field soil taken after the paddy field was drained and dried for 3 to 6 months. During the drying period, no crops were sown and the soil was turned over 2 to 3 times. It is obtained by mixing ash and woodland soil (native soil of hillside woodland) according to a weight ratio of 1:2 to 3;

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, and weeds begin to bud from April to May. After budding, we turn on the two-way nozzles for 3 to 5 minutes of mist spray every night. We don’t pick weeds in the first year of budding. Prune the thorny fir tree, keep one main branch, remove the tops of the other thorny fir seedlings to make the height between 1.4 and 1.6m, and sow ryegrass on the second planting ground in the first ten days of August of the second year. Add 2kg of Bacillus subtilis GB03 bacterial solution and 1.5g of ammonium molybdate to soak for 4-4.5 hours per 1kg of seeds. The Bacillus subtilis GB03 bacterial solution is prepared by diluting the Bacillus subtilis GB03 mother liquor 10 times, and the OD ₆₀₀ in the Bacillus subtilis GB03 mother liquor After soaking, the ryegrass seeds are mixed with 8kg of calcium magnesium phosphate fertilizer and 10kg of fire fertilizer soil for sowing. The sowing amount of ryegrass seeds per mu is 0.8kg. When the ryegrass grows to a plant height of 40-45cm, the first time Harvested as pasture grass, the stubble of 5-8cm is left at the first harvest to promote tillering and regeneration of ryegrass. When the ryegrass grows to a plant height of 35-40cm, the second harvest is carried out and the harvested pasture and leaves are covered in the second harvest. 1. On the surface of the second planting ground, 1-3 cm of stubble was left during the second harvest. In September, a 50 cm deep planting hole was dug on the second planting ground, and 2.0 kg of green manure was put into the bottom of the planting hole, and then 1.5 kg of poultry Livestock manure and 2.0kg of cake fertilizer are compacted, covered with plastic film for decomposing, remove the plastic film after decomposing, turn and spread the fertilizer in the planting hole, and plant 3-4 year old tea saplings in November. The cedar trees are arranged in a staggered interval, and the irrigation is stopped after the frost;

S4: From the third year onwards, repeat the following operations every year: start to irrigate after the waking of insects and apply tea industry fertilization and poultry manure to the tea leaves. The amount of poultry manure applied is 160-170kg/mu. Apply a budding fertilizer once to the vegetables, after the tea leaves germinate and the weeds sprout, turn on the two-way nozzles for 3-5 minutes of mist spray every night, and pick the weeds 3 to 4 times in April to May, and the tea leaves will not be picked in the third year. Pruning, the tea leaves are picked in the fourth year, and the dwarf branches of the thorny fir are pruned so that the height does not exceed 1.5m. In autumn, ryegrass is sown on the first and second planting grounds. Add 1 kg of ryegrass seeds before sowing. 2kg of Bacillus subtilis GB03 bacterial solution and 1.5g of ammonium molybdate soaked for 4-4.5 hours, the Bacillus subtilis GB03 bacterial solution was prepared by diluting the Bacillus subtilis GB03 mother solution 10 times, and the OD ₆₀₀ in the Bacillus subtilis GB03 mother solution was 0.8-1.0 After soaking, the ryegrass seeds are mixed with 8kg calcium magnesium phosphate fertilizer and 10kg fire fertilizer soil, and the sowing amount of ryegrass seeds per mu is 0.8kg. When the ryegrass on the first and second planting grounds grow to a plant height of 40-45cm, carry out The first harvest is used as agricultural and livestock grass. During the first harvest, stubble of 5-8 cm is left to promote tillering and regeneration of ryegrass. When the ryegrass on the first planting ground grows to a plant height of 35-40 cm, the second harvest will be carried out. The harvested pasture and leaves are spread on the surface of the first planting site, and the ryegrass on the second planting site is buried in the soil of the second planting site after it matures. Irrigation is stopped after the frost falls, and the budding fertilizer is used as fire fertilizer and human. It is obtained by mixing urine storage/urea;

Livestock manure is the feces collected from raising livestock and poultry; sorghum, wheat, and soybeans 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 , adding water and fermenting at 28° C. for 70 days, mixing the fermented product and feed for raising livestock and poultry, and collecting the excrement of livestock and poultry.

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 with stones can play a fixed role in the early stage of forest land transformation, preventing landslides during the rainy season from destroying hillside forest land; two-way sprinklers spray for a short time at night, simulating rainy days, so that Part of the rainwater is sparsely sprayed on the weed sprouts to promote the growth of the welt sprouts and make the welt sprouts stronger; at the same time, the improved soil formulated above is more in line with the best requirements for the growth of welt in terms of acidity and fertilizer. It 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 in the next year. Ziyun The rotting of the leaves and the application of bud-supporting 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.

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 improved soil is prepared by mixing upland soil, peat soil and fire fertilizer soil according to the weight ratio of 0.5:1:0.2, and the budding aid 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. Because of the planting of tea trees, the surface height of the second planting site is set to be 10-15 cm higher than the surface height of the first planting site, and multiple crops are 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.

In addition, the selenium-rich fertilizer obtained by mixing and composting livestock and poultry manure rich in organic selenium with weeds, lime, and cake fertilizer, and the application of livestock and poultry manure after the Waking of Insects, the organic selenium in the poultry manure can be effectively absorbed by tea trees, making The selenium content in tea leaves is greatly improved, and the selenium content in the tea soup made from tea leaves is more than 1.8 times that of the tea soup made from ordinary tea leaves. Fertilization with tea leaves should be used before manure from poultry and livestock. Fertilization with tea leaves can effectively promote the absorption of organic selenium fertilizer by camellia oleifera trees. In addition, it can also have strong disease resistance and increase production.

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, and the fresh leaves of the tea leaves are fat and strong, and there will be no pests and diseases.
