The three-dimensional cover of the tea garden refers to the cultivation of tea in the tea garden and the cultivation of other crops. The teahouse stereoscopic suite is an artificial composite system with multiple inputs, multiple outputs, multiple temporal and spatial changes, and biological production. A reasonable tea room three-dimensional housing can not only enable farmers to obtain higher economic income, but also has obvious ecological benefits. Because the three-dimensional tea plantations can increase the surface coverage, reduce surface runoff and prevent soil erosion, it can also improve the tea garden microclimate, which is conducive to the growth of tea plants.
After practice, the following three-dimensional nesting patterns are suitable for most tea regions: 1 Middle Eucheuma of the tea garden, 2 potatoes in the tearoom; 2 Kinds of hawthorn in the tea garden, and konjac in the middle of the tearoom; 3 Kinds of magnolia in the tea garden, and in the tearoom Kinds of soybeans; 4 kinds of black tea in the tea garden, peanuts in the tea room. The first three models are suitable for high-altitude tea gardens (above 800 meters). The fourth mode is suitable for low-altitude tea gardens.
In order to ensure the double harvest of the tea plantation, the tea farmer obtains better economic benefits, and various crops should be properly matched during the intercropping and give way to each other without affecting each other. The selection of tree species should be adapted to local conditions. It is best to choose taller deciduous trees such as Eucommia ulmoides, hawthorn, honokieus, and black oak. Generally, it is planted at a ratio of 4:1, that is, 4 lines of tea and 1 line of shade trees, 30-50 strains per acre, and the shading rate is about 30%. (Over-density will affect the growth of tea plants, but if it is too thin, it will not cause shading. ). The intercropping crops in the teahouse cannot be planted with high stalk crops, and the best shade-tolerant crops or green manure crops are planted. The plant spacing can be flexibly controlled according to the width of the tea room, the length of the tea age, and local habits. In order to achieve the best effect of the three-dimensional casing, a detailed three-dimensional casing program should be developed to promote favorable cycling of nutrients, prevent soil degradation, maintain the sustainable use of land resources, and maximize economic and ecological benefits.
