Eggplant cultivation method at middle and upper reaches of Yangtze River after later autumn

Abstract

An eggplant cultivation method at middle and upper reaches of Yangtze River after later autumn comprises the steps that tree stock is sown from May 5th to May 15th; scions are sewn from June 5th to June 15th; grafting is performed from June 25th to July 5th; planting is performed 10 d-14 d after grafting is performed, the wide-plot and narrow-trench cultivation mode is adopted, the plot width is 2 m, the trench width is 0.5 m, the row spacing is 0.5 m, and two rows of plants are planted in one plot; no pruning is needed inside a plant growth period, and fruit thinning is performed from the beginning of setting of the third batch of fruits to the end of harvesting; water and fertilizer management is performed, reasonable topdressing is performed after planting and seedling recovering are performed, and insect disease prevention is paid attention to; harvesting is performed 45d to 50 d after planting. According to the method, the heat-resisting disease-resistant, high-yield and high-quality eggplant variety is selected to be grafted with stock solanum torvum with the good disease resistance and good graft compatibility, healthy plants of the grafted eggplants are adopted for oversummer, the plant resistance is good, and the eggplants are high in growth vigor, high in yielding ability, black and shiny in fruit skin color and good in commodity after oversummer through the field thin planting method; the plant disease and insect pest occurrence frequency is lowered, the pesticide usage amount is decreased, and the seedling consumption cost, the labor cost and the production management cost are lowered.

Description

technical field [0001] The invention relates to the technical field of vegetable cultivation, in particular to a method for cultivating eggplant after autumn delay in the middle and upper reaches of the Yangtze River. Background technique [0002] Eggplant (Solanum melogena L.) belongs to Solanaceae Solanum (2n=2x=24), and is an important vegetable in Asia and the Mediterranean region. The Food and Agriculture Organization of the United Nations lists eggplant as the fourth largest vegetable crop. According to the data released by FAO: China's total output of eggplant in 2012 was 28.8 million tons, accounting for 58% of the world's total output, and it is the largest eggplant producer. Eggplant has a large area of ​​planting in the north and south of my country, which can realize annual production. In 2012, the planting area of ​​eggplant in Sichuan was 809,000 mu, and the output was 984,000 tons. Planting autumn-delayed eggplant is one of the main methods to solve the prob...
