Tomato early cultivation method

Abstract

The invention discloses a tomato early cultivation method. The tomato early cultivation method comprises the steps of (1) stubble arrangement, (2) nutrition bed soil preparation, (3) seeding, (4) seeding stage management (5) preparation before planting, (6) fertilizer planning and management, (7) soil preparation and ridging, (8) film selecting and covering, (9) seedling density selecting and (10) planting. In the step (1), autumn crops are directly seeded in July in a greenhouse in a two-film one-straw-mat cultivation mode, and seedling growing is conducted on early spring afterward crops in February of the next year. In the step (2), 25-30m<2> of seedling growing beds need to be prepared for every 668m<2> of planting area and bed soil accounts for 40%, soil accounts for 40% and cow dung which becomes decomposed by 70% to 80% accounts for 20%. In the step (3), potassium permanganate diluted by 1000 times is used for sterilizing summer and autumn crop seeds and copper sulfate diluted by 300 times is used for sterilizing winter crops and early spring crops. In the step (4), the seedling stage management periods of all the crops are 11.20-4.1 and 9-10, watering, thermal insulation and freezing prevention are conducted before winter. In the step (5) a mixture containing 100g of bacteriostatic agents and 15L of water is used for spraying seedlings 10 days before transplanting. In the step (6), if fertilization is planned according to the estimation that 10000kg fruits are produced in every 667m<2>, 38.6kg of pure nitrogen is needed and it is enough to maintain 19kg of the pure nitrogen in the soil. In the step (7), the tilling depth is 30 centimeters, the ridging width is 70 centimeters and the height is 10 centimeters. In the step (8), in the overwintering greenhouse, polyethylene three-layer composite purple light films and polyethylene anti-drop green films are used preferably. In the step (9), about 2900 plants are planted in the greenhouse every 667 square meters. In the step (10) for every 667 square meters, 12kg of CM solid are used and soaked in warm water at the temperature being 40 DEG C for 4-6 houses, the water is added for diluting and the mixed liquid is used for watering the seedling growing beds. The tomato early cultivation method is low in investment and greatly improves the economical benefits of peasants.

Description

technical field [0001] The invention relates to a tomato cultivation method, in particular to a tomato early cultivation method. Background technique [0002] The planting density is high, the watering is frequent in winter and spring, and it is easy to be infected with late blight; the nutrients of zinc, copper, silicon, and molybdenum are not used in summer and autumn, and it is easy to be infected with insect pests and viral diseases; traditionally, cow manure is considered boring, and most people pay attention to only applying chicken manure. As a result, carbon deficiency and excess nitrogen and phosphorus lead to a general reduction in production; Contents of the invention [0003] The purpose of the present invention is to provide a method for early tomato cultivation, which can not only resist insect pests and viruses, but also increase production and correspondingly improve economic benefits. [0004] Technical scheme of the present invention is: [0005] The me...
