1, planting method of cherry tomatoes
Seed selection treatment: before planting the cherry tomatoes, the seeds should be selected first, and the seeds should be full, full and healthy. Suitable seeds can improve the survival rate of planting. Before planting, treat the seeds, soak them in warm water for 3-4 hours, pour them into 40% formalin solution for 20 minutes, and then rinse them with clean water.
Planting soil: Prepare the planting soil in advance. You can choose the location with good leeward and sunny drainage, prepare loose, breathable and fertile soil, and apply the decomposed farmyard manure for blending. Put some calcium superphosphate in one week before sowing, so as to disinfect the soil.
Planting: After the seeds are germinated and exposed, the seeds can be planted on demand. After sowing in the soil, cover with a layer of nutrient soil about half a centimeter to keep the seedbed moist. When the seeds germinate and emerge, they can be ventilated in time to control the growth height. When the seedlings grow with two leaves and one heart, you can choose high-quality seedlings for planting, and after planting, you should backfill and water the roots.
2. Planting techniques of cherry tomatoes
Watering technology: after planting, it is not advisable to irrigate more water before fruit setting. At this growth stage, as long as the soil is kept moist and the plants are not short of water, if the water is too large, the branches and leaves will easily grow in vain and the fruit setting rate will be poor.
When the first layer of fruit enters the swelling stage, it can be watered properly, which is beneficial to the growth and development of branches, leaves and flowers. Excessive soil moisture will affect the plants, and fruit cracking and falling will occur. The depth of irrigation ditch 1/3 or 1/2 is the best for each irrigation. In case of rainy weather, it is necessary to drain in time to prevent stagnant water from causing root rot.
Topdressing technology: The basic fertilizer is the main nutrient for the growth of cherry tomatoes, but the quick-acting fertilizer should be applied in a timely and appropriate amount during the growth process to meet the nutritional comprehensiveness of the cherry tomatoes. A small amount of urea can be applied after the slow seedling stage, and a small amount of urea, calcium superphosphate and compound fertilizer can be applied in combination with irrigation after the first layer of fruit is set.
In the full fruit stage, appropriate amount of ternary compound fertilizer, urea, potassium phosphate and other fertilizers can be topdressing every half month, and foliar topdressing should be strengthened in the later growth stage to promote fruit expansion.
Morphological characteristics of cherry tomatoes
The root system is developed, the regeneration ability is strong, and many lateral roots occur, most of which are distributed in the soil layer 30 cm above the soil surface. Plants grow strongly, with stems and vines self-capped, and fewer varieties; There are infinite growth, and the plant height is more than 2 meters.
The leaves are odd pinnate compound leaves with many thin leaflets. Because the seeds are small, the primary cotyledons and several true leaves are slightly smaller than ordinary tomatoes. The fruit is bright, with red, yellow, green and other fruit colors. The weight of a single fruit is generally10 ~ 30 grams, and the fruit is mainly spherical. The seeds are smaller and heart-shaped than ordinary tomatoes. Dense velvety, 1000-grain weight1.2 ~1.5g.
The fruit is about1~ 3cm in diameter, bright red and transparent (there are other new varieties with medium yellow, orange yellow and emerald green), which have the best of both worlds and are favored by consumers. The plant of this variety grows rapidly, and the fruit can be matured after 70 days of seedling planting, and it can be picked continuously for 3 months, with a yield of more than 4000 kilograms per mu, with good benefits.
