Description

A kind of interplanting method of selenium-enriched tea leaves

technical field

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

Background technique

Myrtle, scientific name Ziji, is a perennial fern that exists widely in the Dabie Mountains. Weed is rich in protein, vitamins and various trace elements such as potassium, calcium, and scales. Weed can not only be made into delicious dishes, but also has anti-cancer, heat-clearing, detoxification, weight loss, beauty and other effects. Viruses such as Japanese encephalitis have obvious inhibitory effects, and are long-term export and best-selling vegetables overseas, especially to Japan.

At present, most of the mycelium is collected from the wild. Although there are also local experiments and artificial planting, its yield is low. The collected myrtle has thin stems and poor quality. After one or two years of picking, the myrtle will wither or no longer bud.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a method for interplanting selenium-enriched tea leaves, which can effectively solve the above-mentioned problems.

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

A method for interplanting selenium-enriched tea leaves, which refers to a method for interplanting myrtle, tea leaves and Chinese fir on hillside woodland, and specifically includes the following operation steps:

S1: The hillside forest land is prepared in a step-like manner. After the land preparation, each planting area is opened along the contour line of the hillside. The outside of the slope between adjacent planting areas is built with stone piles. The middle of each planting area is provided with water. The ditch is opened along the length direction of the planting ground and the partitions are arranged at intervals along the length direction of the water ditch. A third water outlet is set 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 water outlet with the smaller height among the first and second water outlets. The water outlets are arranged at intervals and staggered. The top water 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 of the water outlet directions of the two-way nozzles points obliquely to the side wall of the dam ridge, and the other water outlet direction of the two-way nozzles points downwards to the side away from the dam ridge. The ditch divides the planting land into the first planting land located on the The second planting land outside the ditch, the first planting land is filled with improved soil, and the improved soil is prepared by mixing dry field soil, peat soil and fire fertile soil in a weight ratio of 0.5:1:0.2~0.8:1:0.4 The dry field soil is the paddy field soil taken after 3 to 6 months after the paddy field is drained and dried. During the drying period, no crops are sown and the soil is turned over 2 to 3 times. It is prepared by mixing with woodland soil (the native land of hillside woodland) according to the weight ratio of 1:2 to 3;

S2: In the spring of that year, 4-5-year-old pine tree seedlings were planted on the second planting ground at intervals. After the thorn fir seedlings survived, the trunk of the thorn fir seedlings was cut off, and the truncated part was treated with anti-corrosion. Seedlings of thorn fir were produced. In the autumn of the same year, artificially propagated/wild weed seedlings were planted at intervals near the bottom of the dam ridge on the first planting ground, and irrigated in the ditch. The height of the water surface in the ditch was lower than that of the first planting ground. The height of the ground surface is 12-17cm. After the frost falls, stop irrigation and cover the surface of the first planting ground with a layer of leaves;

S3: Start irrigation after the sting in the second year, and sprouted stalks start from April to May. After sprouting, turn on the two-way nozzle for 3-5 minutes of mist spraying every night. The sprouting will not be picked in the first year. The thorn fir tree is pruned, and one main branch is retained, and the remaining thorn fir seedlings are topped to make the height between 1.4 and 1.6m. It is harvested and covered with leaves on the surface of the first planting ground. In September, a 50cm deep planting hole is dug on the second planting ground, and 2.0kg of green manure is put into the bottom of the planting hole, and then 1.5kg of livestock manure, 2.0 1 kg of cake fertilizer is compacted, covered with plastic film to decompose, remove the plastic film after decomposing, turn over and spread the fertilizer in the planting hole, and plant 3-4 year old tea seedlings in November. Arrangement, stop irrigation after frost falls;

S4: Starting from the third year, repeat the following operations every year: start irrigation after the sting, and apply tea industry fertilization and livestock manure to the tea leaves. The application amount of livestock manure is 160-170kg/mu. Apply bud-facilitating fertilizer once to the vegetables, turn on the two-way nozzle for 3-5 minutes of mist spray every night after the tea germinates and the sprouting buds of the scallions, pick 3-4 times the s. Pruning, picking tea leaves from the fourth year, pruning the short branches of the thorn fir tree so that the height does not exceed 1.5m, sowing vetch in the first planting ground in autumn, and sowing clover and vetch in the second planting ground After it is mature, it is harvested and covered with leaves on the surface of the first planting field. After the clover is mature, it is turned and buried in the soil of the second planting field. After the frost falls, the irrigation is stopped, and the bud fertilizer is used to store fertile soil and human urine. Liquid/urea mixed preparation;

Poultry manure is the manure collected by raising livestock and poultry; sorghum, wheat and soybean are crushed 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, the fermented product and feed were mixed for raising livestock and poultry, and the excrement of livestock and poultry was collected.

The most important thing in the planting of weeds is the control of water and fertilizer. Weeds like water and shade, but they are also afraid of waterlogging and are extremely harsh on the growing soil. Through the transformation of the above-mentioned hillside woodland, the irrigation system formed by the ditch can make the water flow evenly irrigate the whole hillside woodland, and at the same time, the water level in the ditch is controlled to be 12-17 cm lower than the surface of the first planting land, so as to ensure the happiness of the weed. Water irrigated and there will be no waterlogging. Planting Mycelia near the bottom of the dam ridge is far better than planting on the flat ground. The Mirena is affected by the dam ridge, so that the new stems and leaves grow to the side away from the dam ridge, making its The plant hormones in the plant stimulate the roots to germinate more spores and increase the yield. At the same time, the setting of the dam can make the water flow above the first planting ground not flow from the surface of the first planting ground but penetrate into the water ditch from the lower part, preventing In addition, the dam ridges built with stones can play a fixed role in the early stage of woodland reconstruction, preventing landslides from destroying hillside woodlands during the rainy season; bidirectional sprinklers spray for a short time at night to simulate rainy days, making Part of the rainwater is sparsely sprayed on the sprouts to promote the growth of sprouts and make sprouts thicker; at the same time, the improved soil prepared above is more in line with the best needs for the growth of sprouts in terms of acidity and fertilizer. It makes the myrtle more sturdy. In addition, astragalus can grow luxuriantly on the soil of the first planting site, and the harvested astragalus and leaves are covered, so that the myrtle can better overwinter and ensure that the myrtle will germinate in the coming year, and the purple cloud The rot of English and leaves and the application of bud-aiding fertilizer can well supplement the fertility of the first planting field and adjust the acidity, so that the weeds can be picked every year. The thorn fir tree has low reproduction cost, high survival rate, and fast growth. After cutting off its main branches, a large number of new seedlings will grow in the tree pockets, which can quickly form a shading fence around the spruce, ensuring the The demand of vegetables on the growing environment, and at the same time shorten the cycle of the entire woodland transformation. Of course, the above is just a brief description of the main role played by each factor alone. Through the coordination of each factor, the swede can be harvested with high yield every year, and the picked succulent is strong and of good quality.

The detailed plan is:

The height of the dam ridge is 60-80 cm, the thickness of the improved soil filling is 30-35 cm, a sandy soil layer is arranged on the lower side of the improved soil filling layer, and the bottom of the dam ridge extends into the sandy soil layer. After the second year, tea trees are planted on the second planting ground. The tea trees are located inside the thorn fir trees and are arranged in a staggered manner with the thorn fir trees. The improved soil is prepared by mixing upland soil, peat soil and fire fertile soil in a weight ratio of 0.5:1:0.2, and the bud-aiding fertilizer is prepared from 50kg fire fertile soil and 10L 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 lush, as if a fence is formed on the outer side of the ditch. At this time, larger tea saplings are planted on the inner side. It can grow well. Due to 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 benefit. In addition, thorn fir trees and weeds are pest-free crops. Through interplanting, the phenomenon that large tea leaves are prone to diseases and insect pests can be eliminated, and the economic benefits of the entire agriculture can be improved.

In addition, the selenium-rich fertilizer obtained by mixing the livestock and poultry manure rich in organic selenium with weeds, lime and cake fertilizer, and the application of the livestock manure after the sting, the organic selenium in the livestock manure can be effectively absorbed by the tea tree, making the The selenium content in tea leaves is greatly increased, 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. The tea flushing fertilization should be used before the livestock manure. The tea flushing fertilization can effectively promote the absorption of the organic selenium fertilizer by the camellia oleifera tree, and also has the effect of strong disease resistance and yield increase.

The above-mentioned technical scheme can significantly improve the yield and quality of Myrtle, and after the third year, the Myrtle can be picked every year, and the fresh leaves of the tea leaves are sturdy, and no pests and diseases appear.
