The invention also provides a greenhouse planting method, which adopts the greenhouse system; the method specifically comprises the following steps: the greenhouse in the greenhouse system is built on the planting ground surface, and an annular water-blocking enclosing barrier is dug around the greenhouse, so that the dry water-lack state is kept within the range of the planting ground depth D1 in the greenhouse under the action of the annular water-blocking enclosing barrier; the water supply pipe is deeply buried in the range of the planting depth D2 in the greenhouse, and the root of the planted plant reaches the periphery of the water supply pipe; in the drip irrigation process, if the humidity value detected by the lower humidity sensor is lower than a set value, the water collecting container is controlled to supply water to the water supply pipe, and when the humidity value of the upper humidity sensor is higher than the set value, the water collecting container is required to stop supplying water to the water supply pipe.

The crops 100 in the invention can be any plant with developed root systems, such as vegetables, fruit trees and the like, which can be planted in a greenhouse, taking the crops 100 as an example, in the process of planting grape seedlings (the root systems reach 30CM below the ground or more), or the grape seedlings grow for more than one year, when the root systems of the grape seedlings reach 40CM below the ground, grooves are dug on the ground in the greenhouse, the depth D2 of the grooves is in the range of 30CM-60CM, the water supply pipe 6 is buried at the depth 45CM, the lower humidity sensor 92 is buried at the depth 60CM, and in the actual operation, the upper humidity sensor 91 is placed at the depth of 30CM from the ground surface in a layer-by-layer buried mode, so that a dry area is formed on the soil layer of the ground surface in the range of 0CM-20CM from the ground surface, a middle soil layer of 20CM-30CM is a buffer area, and a deep soil layer in the range of 30CM-60CM from the ground surface is a wet area, so that the soil layer of the ground surface of 0CM-20CM is kept in a drought and water shortage state is ensured; in the process of irrigating the grapes, the controller dynamically controls the water supply pipe 6 to supply water for irrigation according to the detection values of the upper humidity sensor 91 and the lower humidity sensor 92, meanwhile, the water content in the soil can be adaptively adjusted according to the needs of different growth stages of the grapes, and the optimal growth environment can be artificially provided for the grapes by matching with the adjustment of the temperature and the illumination intensity.

The annular water-blocking enclosure is arranged at the lower part of the greenhouse, and is combined with the greenhouse to collect all precipitation, so that the ground surrounded by the interior of the greenhouse cannot directly obtain water supply from the exterior of the greenhouse, the water supply pipe is buried below the ground, the burying depth of the water supply pipe is reasonably designed according to the growth depth of crop roots planted in the greenhouse, so that the water conveyed by the water supply pipe can ensure that soil layers near the ground depth keep a drought state under the condition that the growth requirement of crops is met, weeds cannot germinate or grow in the soil near the ground, the purpose of no grass is realized, meanwhile, the ground in the greenhouse keeps a drought state, the humidity in the greenhouse is reduced, bacteria and insects are difficult to grow and reproduce on crops in a dry environment, the effect of preventing diseases and insect pests can be achieved, the pesticide consumption of a greenhouse system is reduced, and the purpose of green and environment-friendly planting is achieved; in addition, because the water collecting container collects the water collected by the greenhouse water collecting tank in the rainy day, the water collecting container is positioned above the water supply pipe, so that the water supply pipe can be supplied with water by utilizing gravity, the consumption of electric energy is reduced, in addition, because the water supply pipe is buried in the soil layer, the evaporation amount of ground water is less, the water consumption is reduced, and the quality of agricultural products is improved. The greenhouse system can realize the purpose of no grass without herbicide, manual and animal power weeding and mechanical weeding, greatly reduces labor cost and mechanical cost, avoids the problem of pesticide residue caused by the herbicide on crops, fundamentally realizes the safety of agricultural products and food, protects the health of consumers, effectively reduces the plant diseases and insect pests of the crops at the same time, reduces the pesticide dosage for preventing and treating the plant diseases and insect pests, and achieves the purpose of green and environment-friendly planting. The harmless greenhouse can effectively reduce water consumption, automatically allocate unbalance of rainfall among areas, automatically adjust contradiction between rainfall in each time period and demand of crops, realize optimal matching, greatly save water resources, solve the problem of river and lake dryness caused by excessive development of groundwater, and reproduce graceful environment of the green water in the Qingshan; the harmless greenhouse can intelligently control the water, illumination and temperature required by the optimized climate index of crops, so that the optimization of the quality of agricultural products is realized.
