High-quality long eggplant cultivation experience

Today, in the cultivation of greenhouse vegetables, we often encounter such a problem: the same variety, the same planting season, the efficiency of the greenhouse varies greatly. How can we get high yields and create high returns? Here are some lessons to share:

Experience one, choose the species.

The selection of long-tolerance varieties with strong cold tolerance and high yield is an important guarantee for high-yield and high-productivity of overwintering and long-lasting eggplant. Most of the original planting eggplant king, but eggplant king poor cold resistance, winter fruiting is not good, the yield is low. After the introduction of excellent long-shelled varieties such as Breitah and 765, the eggplant king was gradually eliminated. Therefore, it is recommended that with the continuous promotion of production and market demand, more suitable eggplant varieties should be selected.

Second, grafting, disease prevention and high yield.

Verticillium wilt and root-knot nematodes were once a big problem in eggplant production, which seriously affected the yield and production efficiency. The application and popularization of eggplant grafting technology solved the above problems. Grafting technology is the use of strong root system of eggplant rootstock, not only enhance the comprehensive disease resistance of plants, but also significantly increased production.

Experience 3, disinfection of greenhouses.

Before planting long eggplant seedlings, a high-temperature shed was used during the summer break to kill pathogens in the soil. In particular, in greenhouses with long sheds, there are many pathogens in the shed, and high-temperature sheds are used to sterilize them, which can effectively reduce the incidence of disease during eggplant growth. June-August coincides with the season of high temperature and high light. At this time, calcium cyanoaminate (Zhuangbobo, etc.) can be mixed with appropriate amount of straw to carry out the shed for 10-15 days. It can effectively kill pathogenic bacteria and weed seeds in the soil and supplement fertility, creating a good greenhouse environment for squat production.

Fourth, focus on prevention of gray mold.

Botrytis cinerea is an important obstacle to the eggplant yield and benefit in spring. Once a disease occurs, the number of pathogenic spores is large and it is difficult to control. Therefore, we must do a good job in prevention before the occurrence of gray mold: First, pick flowers, reduce the chance of infection. The second is to add kaiser, acetaminophen and other agents to prevent the invasion of Botrytis cinerea. The third is the combination of ventilation and humidity removal, and chemical control. You can choose to spray 600 times liquid to the farmer, or etchant, etc. for control of spraying.

Experience five, scientific fertilization.

In greenhouses grown year after year, the high salt content in the soil will inevitably affect the normal growth of the crop. Therefore, the shed soil should be improved before planting. The measure is to re-apply organic fertilizer and biological bacteria fertilizer at the bottom of the plant. Into the result period, in order to prevent premature aging of plants, promote root development and increase yield, pesticide compound fertilizer can be applied in a flushed manner, especially in the case of continuous rainy days, and the loss caused by even cloudy days can be minimized. Into the higher temperature, you can flush the application of potassium nitrate compound fertilizer, mu Chong Shi 20-30 kg or so, can not be a one-time flushing too much, so as not to cause damage.

Experience 6, plant adjustment skills.

In the cultivation of a large quail eggplant, the amount of pruning leaves must be appropriate, and the leaves cannot be picked too early or too late to prevent the lack of photosynthetic products and affect the growth and development. Using pinching seedlings to regulate leggy plants. Spotted the "crazy" plants, from the top of the seedling branches down, in the third quarter with two fingers gently pinch, let it put "ring" water, so that the transmission of tissue damage is not up to transport Nutrients stagnate and grow. After 3-5 days, the wound healed into a “cockroach” and normal growth resumed.
