Embodiment 1

[0038] (1) Variety selection: take the fusarium wilt-resistant variety "Jinfei" as the cultivated variety;

[0039] (2) Greenhouse preparation and disinfection: select a single-slope plastic film solar greenhouse with a PO film on the front slope; apply lime nitrogen 35kg / mu, keep the soil humidity at 10%, cover the plastic film, and carry out soil disinfection; ignite sulfur and carry out air fumigation.

[0040] (3) Seedling cultivation: In mid-August, seedlings were sown in plug trays, and tomato seeds were soaked in 10% trisodium phosphate solution for disinfection, and the germination was accelerated to "lubai"; peat, organic fertilizer, vermiculite and perlite were used in a volume ratio of 6:2 : 1:1 mixed as the sowing substrate, sow dewy white seeds, cover with soil 1 cm, cover with film to keep warm, remove the film after germination; maintain the temperature at the seedling stage at 25°C, and the water should be based on the principle of seeing dry and wet to prevent ...

Embodiment 2

[0046] (1) Variety selection: take the fusarium wilt-resistant variety "Jinfei" as the cultivated variety;

[0047] (2) Greenhouse preparation and disinfection: choose a single-slope glass solar greenhouse; apply 30 kg / mu of lime nitrogen, keep the soil humidity at 10%, cover with plastic film, and carry out soil disinfection.

[0048] (3) Seedling cultivation: In mid-August, seedlings were sown in plug trays, and tomato seeds were soaked in 10% trisodium phosphate solution for disinfection, and the germination was accelerated to "lubai"; peat, organic fertilizer, vermiculite and perlite were used in a volume ratio of 6:2 : 1:1 mixed as the sowing substrate, sow dewy white seeds, cover with soil 1 cm, cover with film to keep warm, remove the film after germination; maintain the temperature at the seedling stage at 25°C, and the water should be based on the principle of seeing dry and wet to prevent seedlings from growing excessively.

Abstract

The invention provides a method for cultivating tomatoes in a solar greenhouse, and belongs to the technical field of vegetable facility cultivation. The method mainly adopts one-furrow double-row staggered row planting, and comprises the following steps: during first row planting, the initial plant spacing is 47-49 cm, 3-4 plants are taken as a plant spacing unit, and the plant spacing is sequentially reduced to 43-45 cm, 39-41 cm, 35-37 cm and 31-33 cm; the initial plant spacing is 49-51 cm when the second row is planted, and the plant spacing is sequentially reduced to 44-46 cm, 39-41 cm, 34-36 cm and 29-31 cm by taking 3-4 plants as a plant spacing unit. According to the method, the tomatoes are cultivated in different plant spacing in the same bed and two rows are staggered, so that the plants can fully utilize short and weak illumination in winter in the north; the plant spacing close to the front slope of the greenhouse is properly shortened, so that the plant photosynthesis is successfully increased under the condition of no additional manual light supplement.

Description

technical field [0001] The invention belongs to the technical field of vegetable facility cultivation, in particular to a method for cultivating tomatoes in a solar greenhouse. Background technique [0002] With the continuous expansion of the area of ​​vegetable facility agriculture in my country, the vegetable facility agriculture in the northern region with greenhouses and solar greenhouses as the main body has also become the main way for the majority of growers to increase production and become rich. Especially in winter, the northern region is cold in winter, and the lowest outdoor temperature reaches -35°C, making it impossible to carry out agricultural production. The market price of vegetables produced in off-season, mainly in solar greenhouses, is high and can obtain higher economic benefits. With the continuous improvement of living standards, while meeting the basic needs of vegetables in winter, people's demand for high-quality vegetables is increasing day by da...
