Background

Due to the continuous planting of a single variety in vegetable facility cultivation, more than 10 kinds of phenol and acid substances with biological toxicity are separated from the tissue and root secretion of various facility horticultural crops such as tomatoes, cucumbers, peppers and the like, and when the phenol and acid substances are accumulated to a certain degree, the phenol and acid substances can influence the growth of the following crops. Some root exudates can also stimulate the growth and reproduction of some harmful microorganisms to cause diseases of next-crop vegetables, thereby causing continuous cropping obstacles. After the same crop is continuously planted, certain specific microbial groups can be enriched, particularly plant pathogenic fungi, so that the occurrence of plant root diseases is facilitated, and the crop yield is reduced year by year. The imbalance of the proportion of soil microorganisms is a direct cause of the reduction of the soil decomposition capability, and the growth and development of elements which cannot be normally supplied to continuous cropping vegetables are hindered indirectly. Thirdly, the increase of harmful fungi in the soil greatly increases the possibility that the vegetables in the later period of continuous cropping are infected by diseases. Such as verticillium wilt of eggplants, wilt of melon crops, bacterial wilt of tomatoes, epidemic disease of hot peppers, clubroot of Chinese cabbages and the like.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Example (b):

referring to fig. 1-3, a cultivation system for preventing the continuous cropping obstacle of solanaceous vegetables comprises a water storage tank 1, a pipeline 2 communicated with the inner cavity of the water storage tank 1 is fixed at the bottom of the water storage tank 1, a suction pump 3 is installed on the pipeline 2, the outlet end of the pipeline 2 is connected with a shunt pipe 5 through a hose 4, a plurality of branch pipes 6 capable of being buried in a field furrow are connected to the shunt pipe 5, and a plurality of water outlet holes 7 are formed in each branch pipe 6 along the longitudinal direction; a hopper 8 is arranged on the pipeline 2 between the water storage tank 1 and the suction pump 3, and an open slot 9 for communicating the bottom of the hopper 8 with the inner cavity of the pipeline 2 is formed in the wall of the pipeline 2 corresponding to the outlet end of the hopper 8; a first flow control valve 10 is arranged on the section of the pipeline 2 between the hopper 8 and the water storage tank 1, and a second flow control valve 11 is arranged on the section of the pipeline 2 between the hopper 8 and the suction pump 3.

In this embodiment, water storage box 1 provides and drips irrigation the water, and each branch pipe 6 of shunt tubes 5 buries underground in the furrow in field respectively, opens flow control valve 10 and two 11 backs of flow control valve, starts the work of suction pump 3, and the water in water storage box 1 flows into in shunt tubes 5 through pipeline 2, evenly drips irrigation in each furrow in field through apopore 7 on each branch pipe 6 and the branch pipe 6 again, realizes driping irrigation in solanaceous vegetables field, the saving water consumption. After the solanaceous fruit vegetable field is planted for a long time, soil nutrient elements in the field are absorbed by plants, the soil is lack of nutrition, and harmful microorganisms are bred in a large quantity; at the moment, before the next round of solanaceous vegetable planting, soil conditioner application, pesticide application, sterilization or fertilization can be respectively carried out; the working process of the continuous cropping prevention device comprises the steps of respectively placing a regulator, a sterilization medicine or a chemical fertilizer into a hopper 8, starting a first flow regulating valve 10, a second flow regulating valve 11 and a suction pump 3, respectively regulating the water flow at the positions of the first flow regulating valve 10 and the second flow regulating valve 11, enabling the water level in the hopper 8 to rise and fall in a reciprocating mode in the hopper 8, enabling part of water flowing out of a water storage tank 1 to wash the regulator, the chemical fertilizer or the chemical fertilizer in the hopper 8 in a reciprocating mode, sucking the water to a shunt pipe 5 through the suction pump 3, and then carrying out drip irrigation on the water to each furrow in a field through each branch pipe 6, respectively achieving sterilization or fertilization of field soil, effectively preventing continuous cropping obstacles of solanaceous vegetables and soil, and ensuring the continuous cropping yield of the solanaceous vegetables.
