Example Embodiment

[0037] Example 1

[0038] (1) Variety selection: The fusarium wilt-resistant variety "Jinfei" is used as the cultivar;

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

[0040] (3) Raising seedlings: In mid-August, use plugs to sow seedlings, soak tomato seeds in 10% trisodium phosphate solution for disinfection, and accelerate germination to "whiteness"; use peat, organic fertilizer, vermiculite and perlite in a volume ratio of 6:2 :1:1 mixed as a sowing substrate, sow dew white seeds, cover with soil for 1 cm, cover with film to keep warm, and remove the film after germination; maintain the temperature at 25 °C in the seedling stage, and prevent the seedlings from growing too long.

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...
