The latest planting method of black tomato

The tomatoes we see in our daily life are basically red, but now there is a new type of tomato on the market, that is, black tomato, which has black fruit introduced from South America in recent years. Its nutritional value is better than that of red tomatoes. It tastes very sweet and is suitable to be used as a fruit. Is there any difference between black tomatoes and ordinary tomatoes? Now let's learn how to grow black tomatoes.

1. Soil preparation and fertilization

Black tomato is generally suitable for planting in sandy loam with fertile soil, good drainage and storage capacity and good soil permeability, or in clayey sandy soil, but not in heavy clayey and pure sandy soil. When preparing the soil, we generally need to divide the seedling land and the planting land, and the soil quality of the seedling land should be as fine as possible, and the soil quality of the planting land can be made as fine as 1.2 meters, and the soil quality of the planting land can not be like the seedling land, but it is necessary to ensure that there is no stagnant water area in the field, at the same time, clean up the impurities in the field, finally sprinkle the bottom fertilizer, turn the bottom fertilizer into the soil and wait for planting.

2. Sowing and raising seedlings

Because the temperature in our country is different from that in South America, and the climate in the north and south of our country is also different, we have to sow seeds according to the specific conditions of the locality. The south of our country basically sows in January and August, while the north can only sow in August. There are two common ways of sowing, namely sowing and strip sowing, which need to wet the soil before sowing, then sow the seeds evenly, press the seeds into the soil and cover a layer of barnyard manure or a layer of straw, which can play the role of heat preservation and moisturization, so as to promote the speed of seed germination.

3. Reasonable close planting

Generally, transplanting can be carried out after the late frost, and the tomato seedlings have basically risen to about 10 centimeters. At the same time, the temperature of the soil has basically reached 10 to 15 degrees, which is just suitable for the growth of tomatoes. Under normal circumstances, it is planted according to the density of 2500 to 3, 000 plants per mu, and the distance of each row is about 50 centimeters. The distance between each plant is about 30 to 40 centimeters. If it is a late-maturing variety, we also need to reduce the density appropriately, preferably planting about 2200 plants. As for the specific planting density, we also need to determine according to the fertility of the soil.

4. Field management

The growth of black tomato needs a lot of nutrients, so reasonable topdressing is needed in addition to adequate base fertilizer, in which the early topdressing is mainly nitrogen fertilizer, but an appropriate amount of potassium fertilizer must be used. or the use of fecal water and plant ash to promote growth, the second topdressing is mainly potash fertilizer when the black tomato blossoms and bears fruit, and a small amount of urea is used to prevent plant aging. Because black tomatoes bear fruit many times, they need to be fertilized every time they bloom, and the type of fertilization is the same as when it blossoms for the first time. The drought resistance of black tomato is relatively strong, generally need to be watered about a week after planting, followed by reasonable watering according to the moist degree of the field. Finally, in the process of his growth, we need to carry out at least three times of ploughing and weeding, and at the same time, we can fight or thinning flowers and fruits during the full fruit period.

5. Pest control

In fact, the most common diseases and insect pests of black tomato are not much different from those of tomato, mainly navel rot, leaf spot, bacterial wilt, early blight, late blight, powdery mildew, virus disease and downy mildew, while the pests are mainly aphids, moths, borers, etc., followed by some physiological diseases, which are mainly caused by improper fertilization. Then we should strictly follow the scientific fertilization method when applying fertilizer. The above diseases are basically fungal infectious diseases, which can be treated with carbendazim, chlorothalonil, Bordeaux liquid and other targeted agents, while pests can be controlled by trichlorfon.
