Embodiment

[0029] A cultivation method of tomato-rice-broccoli in paddy and dry rotation, comprising the following steps:

[0030] (1) Tomato cultivation

[0031] (1) In mid-November, soak tomato seeds in hot water at 55-58°C for 15 minutes at a density of 15-20g / mu, then keep stirring until the water temperature is 30°C, stop stirring, and continue soaking for 6 ~8h, then moisten and accelerate germination at 25~30℃; select tomato varieties with compact plant type, less leaf volume, low temperature resistance, low light resistance, strong disease resistance, high quality, early maturity, high yield varieties, such as Zhongza 302, China 1405, Domery, Buffett, etc.;

[0032] (2) When 60-70% of the germinated seeds are dew white, press 8-10g / m 2 The density is sown on the seedbed with seedling substrate. Before sowing, each cubic meter of seedling substrate is treated with 80g, 50% carbendazim; hole or 50 holes in the nutrient tray; wherein, the seedling-raising substrate comprises peat...

Abstract

The invention discloses a tomato-rice-broccoli paddy-upland rotation cultivation method. The method comprises the steps that (1) soil preparation is conducted, and tomatoes are planted; (2) after the tomatoes are harvested, soil preparation is conducted, and rice is planted; (3) after the rice is harvested, soil preparation is conducted, and broccoli is planted; (4) after the broccoli is harvested, soil preparation is conducted, and planting of the tomatoes for next round is prepared. According to the tomato-rice-broccoli paddy-upland rotation cultivation method, the problem of continuous cropping obstacles in the crop production process can be effectively solved, the crop yield is improved, the crop morbidity is lowered, and the soil fertility is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a cultivation method for tomato-rice-broccoli crop rotation. Background technique [0002] Due to the limited cultivated land, crop continuous cropping is very common, which will easily cause continuous cropping obstacles such as soil salinization, acidification, nutritional imbalance, and aggravation of pests and diseases. The main manifestations are soil-borne diseases, morning and evening blight, etc.; Inhibition, poor plant development, high mortality, and reduced yields. [0003] At present, the prevention and control of continuous cropping obstacles in production mainly include the following methods: soil replacement, selection of disease-resistant varieties and chemical disinfection of soil such as methyl bromide; however, the workload of soil replacement is very large, and it is not conducive to the improvement of soil fertility; disease-resistant var...
