The management measures of eggplant before planting are relatively simple. After the eggplant is planted, many vegetable farmers have not done fine on the field management of eggplant, which causes such problems in the late growth of eggplant, which seriously affects the development of eggplant and Yield. Today, Xiaobian will give you a detailed explanation of the field management measures after eggplant colonization.
First, temperature management
The slow seedling period generally takes 7-10 days, the daytime temperature is about 30 °C, the nighttime is about 20 °C, and the ground temperature is about 25 °C. The relative humidity is about 75%. The roots are strong and the seedlings are solid. Temperature control is achieved primarily by uncovering the straw curtain and the switch vent.
The principle of temperature change management after slow seedlings is to gently discharge the air before sunrise. After sunrise, the temperature is quickly raised to 25-30 °C until the afternoon, in order to fully carry out photosynthesis and accumulate nutrients in the morning. At about three o'clock in the afternoon, the temperature is lowered to 18-22 ° C by air release, and the temperature is maintained at 15 ° C in the evening to midnight to promote the distribution and transportation of photosynthetic products. Keep the temperature above 13 °C from midnight to the next morning, and reduce consumption to a minimum.
Second, the management of humidity
After the eggplant is planted, it is most suitable to keep the relative humidity of the air between 70% and 80%, but the soil moisture of the eggplant should not be too high, otherwise it will be prone to disease, which is difficult to control.
Third, the management of lighting
Improve greenhouse lighting conditions by plant adjustment, hanging reflective curtains, uncovering curtains, and installing fluorescent lamps. In the flowering and fruiting period, the respiratory inhibitor Sodium Bisulfite 120ppm can be sprayed.
Fourth, the adjustment of the plant: timely pruning of the eggplant, removal of old leaves, diseased leaves, yellow leaves, deformed fruit, etc., so as to save nutrients and can achieve the effect of preventing disease, but also conducive to ventilation and light transmission between eggplant plants.
V. Management of water
After the eggplant is watered after planting, the temperature of the water should be kept at about 20 °C. The method is generally to use dark submerged irrigation under the film. It is necessary to adhere to the principle of applying a small amount of fertilizer and water.
6. Management of fertilizers
1. Lightly applying seedling fertilizer: A week or so after planting, the application of 2-3 times of seedling fertilizer will increase the geothermal and soil cushioning and promote flower bud differentiation.
2, the current flower topdressing: about 6 weeks after planting, the eggplant will enter the flower bud period, for a period of time is the simultaneous development of nutrition and reproductive growth, at this time the demand for fertilizer on the eggplant can be said to be the entire growth stage Period. During the flower buds, 2-3 times of topdressing can be applied, which can increase the rate of pollination, preserve the flowers and preserve the fruit, and prevent and cure diseases.
3, heavy application of fruit fertilizer: in the door of the eggplant "blinking" phenomenon (young fruit exposed bracts, round eggplant such as jujube, long eggplant about 4-6cm), you can spray boron, calcium and other micronutrients 2 -3 times to reduce the occurrence of fruit drop and deformed fruit, and prevent and cure diseases.
4, diligently harvesting fruit fertilizer: When the eggplant is harvested, the second and third layers of fruit (on the eggplant and the four-door bucket) are also inflated, and the fruit is planted on the top, and the fruit fertilizer is applied once. Apply once a day, apply 3-5 times of micronutrients such as boron and calcium to prevent the occurrence of deformed fruit and deficiency diseases.
The above is some of the field management methods introduced by the small series about the eggplant colonization. In fact, it is not only necessary to carefully manage the eggplant after planting, but also includes the whole stage of eggplant growth, and all the farmers need to go to the field to observe. In this way, the growth dynamics of eggplant can be checked in time, and management measures can be taken in time.
