Method for cultivating over summering tomato plants in sunlight greenhouse

Abstract

The invention relates to a method for cultivating over summering tomato plants in a sunlight greenhouse. The method includes the steps that tomato plants are fixedly planted on the two sides of each concave-shaped cultivation ridge; a drip irrigation zone is arranged in the middle of each concave-shaped cultivation ridge; a white ground silver reflective film covers each concave-shaped cultivation ridge, the silver reflective face of each white ground silver reflective film faces towards the ground, and an east-west direction steel wire is fixed at the north end of a planting line; a north-south direction steel wire is drawn in the longitudinal direction of the middle of each concave-shaped cultivation ridge; the north-south direction steel wires and the concave-shaped cultivation ridges are the same in length, and the two ends of each north-south direction steel wire are fixed on two steel wires; the white ground silver reflective films cover the north-south direction steel wires, the concave-shaped cultivation ridges are fully covered, and the silver faces face towards the ground. When the mean highest temperature in the sunlight greenhouse is 32-36 DEG C, the method can be used for fixed planting so that the ground temperature of the roots of the tomato plants 5-15cm away from the ground can be stabilized below 28 DEG C, the temperature is lowered by 2.3-4.4 DEG C on average compared with a conventional planting method, according to the conventional planting method, the ground temperature of the roots 5-15cm away from the ground is above 28 DEG C, the occurrence rate of tomato plants yellowing leaf curl virus diseases is low (only 4.1%), the occurrence rate can be reduced by 55.4-67.3% compared with the conventional planting method, and the difference is extremely obvious.

Description

technical field [0001] The invention relates to a method for cultivating tomatoes, in particular to a method for cultivating oversummer tomatoes in a solar greenhouse, and belongs to the field of agricultural technology. Background technique [0002] In recent years, oversummer tomato cultivation in solar greenhouses has become more and more common. However, the growing period of oversummer tomato is in the high temperature season, the prevalence of diseases such as viral diseases, the influence of high temperature, strong light, and dry environment often make the cultivation and management of oversummer tomato encounter difficulties, which makes growers very troubled. At present, yellow leaf curl virus disease has become a major obstacle to oversummer tomato cultivation in solar greenhouses. The research shows that during the tomato production period (mainly in the early and mid-term), the critical indicators for the recurrence of tomato yellow leaf curl virus disease are ...
