The economic benefits of tea garden intercropping are good, and what are the unfavorable factors of

The first consideration is not to affect the growth of tea in the tea garden, and not to cause a reduction in tea production; secondly, economic benefits can be considered; Finally, it is necessary to consider the landscape effect, whether it can improve the quality of tea, so the new large-scale tea garden due to dense planting, can not be interplanted, there is no interplanting problem needs to be cared for, the first two years can be planted with corn, sorghum and other high-pole crops, can also be interplanted soybeans, sesame, broad beans and other medium and high-pole crops, but also interplanted Yueji, peony and other flowers. As long as the crops are valuable in the local area, they can be planted and planted.

We found that interplanting legumes in tea plantations can effectively promote nitrogen uptake. Rhizobia in legumes, in particular, are able to fix nitrogen in the air and increase nutrients in the soil. Therefore, we can interplant soybeans, mung beans and other legumes in the tea garden.

If exposed to the fierce sun in the summer, it is easy to get sunburned. In order to protect the tea seedlings, we take the interplanting of corn in the tea garden, which not only protects the growth of the tea seedlings, improves the vitality, but also increases the income, the corn can be harvested within three years, and the tea can be harvested after three years.

I once tried to grow corn in the open space of Chashan, but unfortunately the weather was not good, and the drought caused many corn seeds to not emerge, and even the corn seedlings did not grow well due to the drought, because there were no irrigation facilities, and I had to watch them slowly decay, and the result was that there was almost no harvest. But not too dense, so as not to block the sun to affect the industrial output, the advantage of this is that the peach tree blooms in March every year, the flowering period is nearly 1 month, spring tea picking, the flower season, the peach blossoms all over the mountains will become a landscape, will attract tourists to come to enjoy the flowers, with flowers to attract tourists.

Tea intercropping. In some tea gardens close to mountainous areas, especially in hillside areas, the climatic and environmental characteristics of the whole tea plantation can be improved through the mixed planting of tea trees and economic trees, so as to increase the effective use of land and improve the output efficiency of land per unit area. For example, like our local area.

First, it is not conducive to the overall mechanized operation.

One of the most important aspects of the requirements for the construction and management of modern tea plantations is the difficulty of mechanized operations. Because as labor becomes more and more expensive, coupled with the promotion of mechanical application more and more deeply, the future tea garden will be a modern way based on mechanized management. However, interplanting economic plants or planting forage leguminous plants in tea gardens has a certain hindrance effect on mechanized operation, so these are some adverse effects of tea garden intercropping on management.

Second, it is not conducive to the prevention and control of pests and diseases in tea gardens.

As we all know, in the management of modern tea gardens, the requirements for pesticides are very strict, and many ecological tea gardens do not use pesticides at all, but if they are planted on a large scale, they will inevitably face the problem of pests. Originally, the pests and diseases of the tea garden were relatively single and stable, and if intercropping was carried out, it may bring other fruit trees or pests and diseases native to economic plants. In this way, it will increase the difficulty of pest control, resulting in low economic benefits of tea trees, or low overall benefits of fruit trees and tea trees interplanted in the entire tea garden.

Summary. Dear, I have seen your question, I am preparing the answer for you, please wait two minutes thank you!

The reason for planting small shrubs between the ridges of tea gardens is the main purpose of interplanting rape and soybeans in tea gardens.

Dear, I have seen your question, I am preparing the answer for you, please wait two minutes thank you!

Dear, hello, it is a pleasure to serve you, this is the information I provide to you Soybean is a leguminous plant, which envy rhizobia has a nitrogen-fixing effect. Planting soybeans in tea gardens has the following effects: 1. Planting soybeans in tea gardens can improve the soil and improve soil fertility.

Second, soybean straw pressing green, can improve the soil has.

nutrients.

Hello dear, it is a pleasure to serve you, this is the information I provide to you Soybean is a leguminous plant whose rhizobia has a nitrogen-fixing effect. Planting soybeans in tea gardens has the following effects: 1. Planting soybeans in tea gardens can improve the soil and improve soil fertility.

Second, soybean straw can improve the nutrient content of soil leakage.

Dear, I hope mine is helpful to you, dear.

Dear, I hope you can give this service a thumbs up, thank you!

It is better to interplant leguminous green manure (such as vetch and milk vetch) and leguminous cash crops (such as broad beans and soybeans) in tea gardens. Of course, the size of the plant depends on the space between the rows of tea trees. When the tea tree is small, there is more open space between the rows, you can interplant broad beans, soybeans and the like, and you can also interplant green seedlings, such as osmanthus, moon season and other flower shrubs, small trees, tea garden idle land, wasteland can also be used to plant melons and fruits.

The forests and vegetation around the tea plantation are well preserved, and no factories, mines, workshops, and earthen kilns that emit harmful substances are allowed to be built within 5km. The soil and water sources are free of pollution. The distance between the tea plantation and the field crops and residential areas is more than 1km, and there is a separation zone.

It is advisable to choose the slope to face south or southeast, the slope is below 25 degrees, the soil layer is more than 1m thick, rich in organic matter, the soil is slightly acidic, there are available water sources nearby, and the garden with convenient transportation is developed to establish a tea garden. ‍

Tea intercropping. Intercropping should emphasize the rational combination between species, and there is often symbiosis and mutual benefit between species. If the positive tree species and the negative tree species are combined, their respective light amplitudes can be used separately; Deep-rooted tree species are combined with shallow root tree species to absorb nutrients at different levels.

However, there is often competition and restraint between species. China's ancient books have a clear record of the selection of tree species in the tea garden, such as the "Beiyuan Farewell" records that only the wood is left, and the prosperity of the paulownia wood is suitable for tea; In the "Tea Solution", it is more specifically proposed: the tea garden should not be mixed with evil wood, but cinnamon, plum, Xinyi, magnolia, pine, green bamboo, etc., and the planting in between, is also enough to cover the frost and snow, cover the autumn sun, and under it can be the product of the orchid, the chrysanthemum and the Qingfang.

Tea tree is a kind of cash crop that grows in the shade of the large forest, and has formed the characteristics of shade tolerance, temperature preference, humidity preference, and acid requirement after a long history of reproduction process in imitation of caves. We plant tall trees such as fir trees, metasequoia, black tree, acacia, and paulownia around the tea garden and on the side of the ladder and roadside of the terraced tea garden to create an artificial ecological environment to meet the needs of tea tree growth and development.

Tea fruit intercropping. Fruit trees such as hawthorn, peach, cherry, chestnut, persimmon and other fruit trees can be interplanted in the large open space, and as long as they are properly managed, there is no impact on the yield and quality of tea trees.

Camellia intercropping. In the tea garden, intercropping moon, chrysanthemum, orchid, safflower, peony tremble; Honeysuckle, mast flower, laurel, Xinyi, magnolia, etc., can be planted at the edge of the garden and ladder, which have both medicinal and economic value.

Intercropping of tea farmers. For tea plantations with no more than 60% coverage, tea farmers can implement intercropping, three plantings and three incomes a year. winter intercropping of broad beans, peas, vegetables, vetch, etc.; Pure soybeans and peanuts are prepared for summer intercropping; Autumn intercropping mung beans, etc.

In order to ensure the growing period of crops, each intercropping is planted about half a month before the harvest of the crops.

Trees (trees), shrubs (tea trees), grasses (green manure or crops) are planted. For tea gardens with a ladder width of about 2 meters and a coverage of no more than 60%, three-dimensional planting of trees, shrubs and grasses is implemented. 2-3 rows of tea trees can be planted in the inside of the ladder, trees (woods or fruit trees) can be planted outside, and crops or green manure can be planted in the middle.
