Cultivation method of weak-light-resistant tomato variety

Abstract

The invention discloses a cultivation method of a low-light-resistant tomato variety. The cultivation method comprises the steps of creating a low-light environment, cultivating seedlings, domesticating, watering and using a growth regulator. According to the cultivation method, the fruit setting rate is guaranteed, meanwhile, the weight of a single fruit can be increased, the fruit setting rate is 95.9-96.5%, and the average weight of the single fruit is 232.7-238.5 g. According to the cultivation method, the leaf specific leaf area can be increased, and the average leaf specific leaf area is 8.45-8.51.

Description

technical field [0001] The invention relates to a method for cultivating low-light-resistant tomato varieties, which belongs to the field of agriculture. Background technique [0002] Tomato originates from the subtropical region and is one of the main vegetables cultivated in my country. Its growth and development require strong light conditions. [0003] In recent years, facility vegetables have developed rapidly, and successive years of production have led to the aging of facility light-transmitting covering materials and the accumulation of dust, which reduces the light transmittance of facilities and seriously affects the quality and yield of vegetables and the sustainable development of facility production. At the same time, due to dense planting, the leaves are shaded from each other, or it is overcast and rainy in a certain growth period, which causes the light intensity of the plant to decrease in a certain period, thereby affecting the formation of some organs and ...

Problems solved by technology

[0004] CN108713464A discloses a low-light resistant tomato planting method, by using growth regulators and other management methods such as water and fertilizer, the photosynthetic rate in low-light environment is improved, However, the activity of calcium-activated ATPase in the leaves of low-light-tolerant tomato showed a trend of high in the early stage, low in the middle stage, and high in the later period during the growth cycle. low fruit weight

[0005] (1) The fruit setting rate of low-light-tolerant tomatoes is higher in low-light environments, but the weight per fruit of low-light-tolerant varieties is lower;

[0006] (2) The specific leaf area (leaf area / leaf dry sample weight) of low-light-tolerant tomato leaves is low in low-light environments, which affects light utilization efficiency;
