In the eggplant production, the falling and fruiting is usually serious, which restricts the increase of the output and is not conducive to the improvement of the production efficiency. The production should be guarded against. The main reasons for falling eggplants are: 1. The temperature is not suitable for the eggplant. The results require a higher temperature. The result is a suitable temperature between 25-30°C. The nighttime temperature should be between 15-20°C. The temperature should be lower than 15°C or higher than 35°C. , In the production of performance as early and less summer results. 2. Bad flowering development of eggplant Flower development is good, flower shape is large, color thick, flower style is longer or equal to the length of the anther, favorable pollination and fertilization, fruiting is good, and poor development, style shorter than anthers, it is difficult to get Pollination, most fell. 3. Lack of nutrients and lack of nutrients, the plants grow thin and weak, nutrients used to maintain growth, the reproductive capacity is low, fewer fruit set. 4. Fertilizer is not timely, improper time, but also is not conducive to fruiting general performance early dressing, plant leggy, resulting in shedding of flowers and fruits. Fertilizer is not timely, plant premature aging ability to reduce, but also unfavorable. 5. Improper proportion of fertilization makes the value of the crop grow or grow weak, the ratio of vegetative growth and reproductive growth of the plant is unbalanced, and it is difficult to establish fruit. 6. Poor photosynthesis Photosynthesis ability, poor flower quality, it is easy to fall off; eggplant is hi-light crops, the strict requirements of the light time, when the light is weak, the plant growth and development slowed into less flowers, flower buds of poor quality. 7. Plant diseases and insect pests lead to decreased photosynthetic capacity, unfavorable photosynthetic product accumulation, and unfavorable flowering and fruit setting. The major diseases and pests that damage eggplant include verticillium wilt, aphids, and red spiders. Verticillium wilt is not pathogenic in the general seedling stage. It usually occurs from the bottom up or from the side to the whole plant during the fruit setting period. The leaves turn yellow between the leaf edges and veins, and then it develops to the half leaves or the whole leaf turns yellow, and the photosynthetic fertility decreases. The accumulation of nutrients decreased and the fruit setting rate decreased. The locusts are more likely to be contaminated and suck the host sap with a needle-like pipette, causing the leaves to shrink, deform, and wither. Red spiders can become larvae or if they can take plant sap, so that the leaves change color or dry, resulting in reduced photosynthetic capacity of the leaves, unfavorable fruit set. Based on the above reasons, appropriate measures should be taken in the production of eggplant in order to promote the increase of fruit set rate and improve the production and management efficiency. The main measures are: Pay attention to promote the growth of the stigma and reduce the proportion of short-stemmed flowers in order to improve the fruit set rate; the key measure in the production is to strengthen the temperature management during the flower and fruit period, within the range of temperature during the result period, the temperature is slightly lower, and the daytime control At about 25°C, the control is between 15-20°C at night, so that the flower bud differentiation is slightly slower, which favors the formation of long column flowers and can effectively control the proportion of short column flowers. In addition, it is necessary to arrange planting cornices in a reasonable manner so that the temperature during the result period will be above 25°C during the day and between 15°C and 20°C during the night. During the summer high temperature period, watering temperature should be taken into consideration. In case of continuous high-temperature weather, shade nets can be used to build shade sheds. To reduce the temperature, promote fruit set rate. 2. Strengthen the management of fertilizers and waters and maintain the growth of the plant, so as to balance the relationship between vegetative growth and reproductive growth, so as to improve the fruit setting rate: especially when the first top dressing should be done in a timely manner, the first layer of fruit should preferably be 3 cm in diameter. Fertilizer topdressing to prevent premature fertilization, resulting in the loss of fruit and fruit, after each fruit is harvested, a top dressing is applied, nutritional supplementation is performed to prevent premature plant failure, resulting in a decrease in production capacity, and it should be noted that the proportion of fertilizer should be appropriate to prevent plant nutrition caused by partial fat The proportion of growth and reproductive growth is out of balance. Particular attention should be paid to the prevention of partial application of nitrogenous fertilizer, leading to the emergence of leggy phenomenon. Generally, the ratio of nitrogen, phosphorus, and potassium suitable for eggplant production is 2:1:1.7. It is advisable to observe the plant during production. In order to balance the growth of the plants, strong growth should be used to control the growth. 3. Strengthen the adjustment of plant shape to ensure that the plants have good permeability, in order to facilitate fruit settling: During production, attention should be paid to the timely removal of old branches and old leaves. Since eggplants usually result in flowering at the tillers, they should pay attention to promoting production and delivery during production. Generally, the first, second and third tillers are mostly effective flowers, which are very good for development and fruit setting. After the four pods, the flower buds are poorly differentiated, the fruit set rate is low, and most of them are invalid flowers. Therefore, they should be removed during production. After childbirth, childbirth is controlled to control the amount of branches in the field and concentrate the nutrient supply so as to facilitate fruit set. 4. Strengthen pest control: In the production, we should strengthen the control of Verticillium wilt, spider mites and aphids. Before sowing, soak seeds with 0.2% of 50% carbendazim WP for 1 hour or soak in 15 minutes with warm water of 55°C. After cooling, the germination was performed; the soil was disinfected with carbendazim per acre in the planting field, and 50% mixed sulfuric acid suspension and 50% carbendazim wettable powder 500 times were used to irrigate the soil in the initial stage of Verticillium wilt. 500 ml. After the occurrence of red spiders, spraying 1.8% of the antibiotics of 2000 times or 2.5% of Uranus 3000 times for control. At the beginning of the locust occurrence, 50% anti-inflamy WP can be sprayed with 2000-3000 times liquid or 21% killing larvae 3000-4000 times liquid or 10% imidacloprid 3000 times sprayed. For pests and plants, the foliar must be sprayed with foliar-bamboo, phytothene, 0.5% urea + 0.5% potassium dihydrogen phosphate in time to perform foliar dressing, nutritional supplements, and increase the photosynthetic capacity of leaves and increase photosynthetic products. Accumulation to increase fruit setting rate. 5. Spray chemicals to protect the fruit, in the 1-2 days before flowering, with 30-40 ml / kg of 2.4-D painted in the calyx or pedicel; after the fruit in the first layer spray 120 milliliters / kg or 180 ml / Kilograms and 200 ml/kg sodium bisulfite can effectively increase the accumulation of substances and increase the fruit setting rate.
