Answer: Practice has shown that the planting density of kiwifruit is too large, leaving too many branches and canopy closure; without applying organic fertilizer, a large number of nitrogen fertilizers are used without paying attention to nitrogen, phosphorus, and potassium; the orchards with high groundwater level have serious onset and are hot and humid. The climatic conditions are the basis of the disease, coupled with poor management, is the objective condition of the disease. Therefore, the fruit growers should pay attention to the management of fertilizers and waters in the management process. According to the law of kiwifruit's demand for fertilizer, the base fertilizer, germination fertilizer, fruit stimulating fertilizer, and strong fruit fertilizer should be applied in one year; pay attention to controlling irrigation, especially the high water level. The area should be drained in time, irrigation should not be too much, or the soil is wet, it will easily cause rot, resulting in weakening of the tree vigor; sparse over the dense branches, thin branches and pests and branches, keep the crown can be ventilated, reduce the temperature and humidity.
The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.
