Tomatoes are rich in nutrients and have many effects, such as beauty and beauty, and are well received by consumers. As a result, the area under tomato cultivation is increasing, especially in facilities. In fact, open tomatoes are of good quality, low price and more popular with consumers. Compared to the production of tomatoes in greenhouses, open-air cultivation is a good option for some vegetable farmers who lack start-up funds, owing to its small investment and rapid performance。
Seed treatment
Before being officially sowed, tomato seeds are impregnated for 20-30 minutes with a mass score of 10 per cent sodium phosphate, then washed with water, then mixed in 55 degrees of warm water, then impregnated for four to six hours after water temperatures have dropped to 30 degrees, and then immersed for four to six hours with disinfected rags, with seed seeding at 25 to 30 degrees, until seed seed seeding is seeded。
Water-water management
The high temperature of open-air tomatoes, which are initially grown in the summer, can cause the field to evaporate too quickly, requiring timely rehydration, which is appropriate for two to three days and should be below the surface。
3. Fertilizer management
In the week or so after planting, we need to have our first fat hunt, a second fat hunt when the first sap is about to mature and the second sibling swells, where calcium phosphate can be applied; and a third fertilisation exercise when the first sibling and the second sibling is taken, where the option should be to switch to nitrous phosphorus to fertilizer, which could be added to the farm。
Four. Plugged chicken and whole branch
After the tomatoes were planted, until the flower was blooming, we had to insert the chicken to avoid a fall in the plant. When we tie chickens, we adjust the ears to the shelf, and the buds to the shelf, so as to increase the capacity for ventilating and promoting the growth of the leaves. The cultivation of pre-maturized varieties is generally based on a single-barrelled whole branch, i. E., a tomato only retains its main stem; later-maturized varieties can grow in the summer, and the whole branch of continuous care can be used. In combination with the whole branch, we're going to do the berries and remove the old and sick leaves in time。
Concluding remarks
In the process of planting tomatoes in the open, we need to make every effort to create a good growth environment for tomatoes and to apply appropriate quantities of fertilizers at the right time to promote their rapid growth. The water is controlled and adapted to the needs of the western reds for growth, with the ultimate aim of increasing yields。
