Problems solved by technology

[0003] At present, measures to improve soil include: crop rotation, which requires a large amount of land; high-temperature disinfection of soil is costly; improving soil texture is labor-intensive and time-consuming
The main disadvantages of the above measures are firstly that crop rotation cannot be carried out in the case of limited land, and secondly, i

Example Embodiment

[0035] Example 1

[0036] The improved tomato breeding field soil that present embodiment provides improves the method for multiple cropping index simultaneously, comprises the following steps:

[0037] S11, in the solar greenhouse, put the matrix into the seedling tray and sow tomatoes, and then cover the matrix and plastic film successively after sowing; when 80% of the seed cotyledons are unearthed, remove the plastic film, and continue to cultivate tomato seedlings;

[0038] S12. When the tomato seedlings have grown to two leaves and one heart, set up a flat border outside the solar greenhouse along the east-west direction, and transplant the tomato seedlings to the flat border, and set a double-layer plastic film covering on the flat border. Shed;

[0039] S13, when the tomato seedling grows to a plant height of 20-30 cm, it is planted in multiple cultivation beds, and each tomato seedling retains two spikes of inflorescences and continues to cultivate after topping;

[0044] Example 2

[0045] The improved tomato breeding field soil that present embodiment provides improves the method for multiple cropping index simultaneously, comprises the following steps:

[0046]S21, in the solar greenhouse, put the substrate into the seedling tray and sow tomatoes, and then cover the substrate and plastic film successively after sowing; when 80% of the seed cotyledons are unearthed, remove the plastic film, and continue to cultivate tomato seedlings;

[0047] In this step, the substrate includes a first substrate composed of peat, perlite and vermiculite, compound fertilizer and carbendazim;

[0048] In the first substrate, the volume ratio of the peat, perlite and vermiculite is 5:4:2, the volume ratio of the compound fertilizer to the first substrate is 1:20, and the carbendazim The volume ratio to the first substrate is 1:20;

[0049] The substrate has both good water retention and appropriate water permeability, which ensures the germination rate...

Example Embodiment

[0062] Experimental example 1

[0063] Tomatoes are sown in the solar greenhouse in the first ten days of March, and the matrix includes the first matrix, compound fertilizer and carbendazim composed of peat, perlite and vermiculite; in the first matrix, the peat, perlite and vermiculite The volume ratio of the compound fertilizer is 5:4:2, the volume ratio of the compound fertilizer to the first substrate is 1:20, and the volume ratio of the carbendazim to the first substrate is 1:20. Sowing in a seedling tray, specifically includes: put the moist substrate into the seedling tray, water thoroughly, the substrate is 1.5cm away from the upper edge of the seedling tray, cover the substrate with 1-1.2cm after sowing, and then cover with plastic film, and wait for 80% of the seeds for about a week The cotyledons are unearthed and the plastic film is removed. During this process, the substrate remains dry and wet, and excessive watering can cause leggy growth. The daytime tempera...

Abstract

The invention provides a method for increasing a cropping index while improving tomato breeding field soil. The method comprises the steps that in a solar greenhouse, a matrix is placed in a seedling disc, tomatoes are sown, and the seedling disc is covered with the matrix and a plastic film sequentially after sowing; after 80 percent of seed leaves come up, the plastic film is removed, and tomato seedlings continue to be cultivated; after the tomato seedlings grow with two leaves and one core, flat furrows are arranged outside the solar greenhouse in the east and west direction, the tomato seedlings are transplanted to the flat furrows, and the flat furrows are provided with an arch shed covered with double layers of plastic films; after the tomato seedlings grow with the plant height ranging from 20 cm to 30 cm, the tomato seedlings are planted to a plurality of cultivation furrows, two ears of inflorescences are reserved for each tomato seedling, and cultivation continues after pinching, wherein the distance between every two adjacent cultivation furrows ranges from 35 cm to 45 cm; after the tomato seedlings bloom and bear fruit, corns are interplanted between the cultivation furrows. According to the method, the cropping index can be increased, the land utilization efficiency can be improved, and the soil is improved.

Description

technical field [0001] The invention relates to the field of breeding, in particular to a method for improving the soil of a tomato breeding field while increasing the multiple cropping index. Background technique [0002] In the process of tomato breeding material separation and generation selection, a large amount of land is used. In the case of limited land for selection, continuous cropping is carried out for many years, resulting in obstacles to continuous cropping, which makes tomato prone to viral diseases, and tomato planted in the open field is prone to sunburn. How to improve the economic benefits of breeding fields on the basis of improving soil, reduce breeding costs, improve land use efficiency, prevent sunburn and reduce the occurrence of viral diseases are of great value to material selection for tomato breeding. [0003] At present, measures to improve soil include: crop rotation, which requires a large amount of land; high-temperature disinfection of soil is...
