In North China, planting is usually done in mid-to-late December. When planting, draw crosses or punch holes on the mulch according to the row spacing between plants, open holes to plant seedlings, pour enough water for planting, and seal the openings of the mulch tightly after the water seeps down. The specific cultivation methods include the following: soil preparation and fertilization according to the scientific requirements of soil testing and formula fertilization, full application of fully fermented and decomposed organic fertilizer or biological bacterial fertilizer plus soil conditioner (medium and trace elements). Selecting good, high-yielding, disease-resistant varieties is crucial.
First of all, tomatoes should be supplemented with trace elements. When they bloom, spray phosphorus, potassium, and boron foliar fertilizers, and also add brassinoids together. Several consecutive operations can increase tomato production and income multiple times, and it is best for the land to be ridged, because cherry tomatoes basically need to be ridged for planting, so that they can be more easily controlled. Secondly, it must be the most efficient. Good drainage and water sources are also very important.
The cherry tomato nursery bed must be watered first. When sowing in early spring, the watering can be appropriately small. In summer, the nursery bed must be filled with enough water. After the water has seeped down, the seeds are spread evenly and then covered with 1 cm. Sieve the soil. 3-5 grams of seeds per square meter of nursery bed, and 6-8 square meters of nursery bed per mu of planting area. After cherry tomatoes seeds successfully germinate, cherry tomatoes must be planted. When planting cherry tomatoes, you must choose soil with relatively rich soil, and the soil must have sufficient fertility, and it is best to use sandy soil, because sandy soil can quickly drain away water.
The disease will harm the leaves, fruits, and stems of cherry tomatoes. Mancozeb or mancozeb is generally used for control; yellow and white seedlings are mainly caused by soil, so fertilization should be done reasonably to supplement the calcium content of the soil. In terms of fertilizer management, in addition to applying foot fertilizer, it is generally necessary to apply fertilizer 2-3 times after the cherry tomatoes enter the flowering and fruiting stage, especially the application of appropriate amounts of phosphorus and potassium fertilizers. The first top dressing can be carried out when the first ear begins to swell. Its cultivation time is the same as that of general tomato cultivation. You can choose to cultivate in the open field. In spring, you can choose to sow in February. Try to choose Seedlings are raised in a protected area and can be planted in late April.
