1. Fertilizing the whole area
30-40 cm deep, combined with 3000-4000 kg of corroded organic fertilizer per acre, 50-60 kg compound fat and 30-40 kg per phosphate. To level the land and make it a tumble of 1-1. 2 metres wide。
Time of planting
Tomatoes are generally grown at a steady spring temperature above 15°c, and in the northern region, usually from late april to early may, the southern region can be properly advanced until late march to early april。
3. Child breeding
The treated seed is spread evenly in the nursery or nursery, with a soil of 1-2 cm thick, watered and soil wet. It is necessary to keep the soil moist during the seeding period, but to accumulate water. The temperature of the seeding period is controlled at 20-25°c and ventilation is observed to prevent the occurrence of disease。
Four
When a seedling grows to four or five leaves, it can be planted. Cultivation density is 50-60 cm range, 30-40 cm range, with 2000-2,500 plants per acre. The seedlings are planted on the ground, which is then filled with water。
Watering
After planting, water is poured in a timely manner, the soil is kept moist during the slow-growing period, and water is properly controlled during the flowering outcome period to prevent longing. The increase in the amount of water is required during periods of fruit expansion and the soil is kept humid but water is avoided。
6. Fertilizing
The base weight is 3000 - 4000 kg of certifiable organic fat per acre and 50 - 60 kg of compound fat. The urea 10-15 kg per acre, ammonium phosphate 15-20 kg and potassium sulphate 10-15 kg per acre of flowering results. During flowering, 0. 2% potassium phosphate solution or 0. 3% urea solution is sprayed every 7-10 days to promote fruit development。
Seven. The whole thing
Take a single branch, keep the backbone and remove all the branches. Timely removal of the base and sick leaves, improved ventilation and reduced incidence of diseases。
Eight. Tie a chicken
When the plant is 30 to 40 cm in length, it is mounted on a timely basis, with a pole or a wooden stick to hold the plant in order to prevent inversion. The chicken is tied every three to four knots, so that the plant is spread evenly on the shelf。
9-frilling fruit
Each ear leaves three or four fruits, and removes the extra flowers and fruit, ensuring that the fruit is even in size and improving its quality。
10. Pest management
Diseases are mainly related to early disease, late disease, viral disease, etc. 75% baccalauremo wettable powder 600 times the liquid or 64% venomicide 500 times the liquid spray. The main pests are aphids, white lice, etc. It can be treated with 10% amphibian humid powder 1,500 times more liquid or 25% lice humid powder 1,000 times more liquid spray。
The above is an introduction to the methods and management of tomato cultivation, which allows for the use of a variety of light-resistant varieties such as the millenium, the beatle, which is full of fruit and green and which is easily productive。
