The normal eggplant flower is large, dark in color and long in style. The stigma of the pistil protrudes at flowering and is higher than the anthers of the stamen. The stigma has a large margin at the top edge of the stigma. It is a star-shaped flower, that is, a long column flower. Occasionally, the production of flowers is small, the color is light, the style is thin and short, and the pistil stigma is covered with stamen anthers when flowering, forming short column flowers. When the style is too short and the stigma is lower than the anther opening, pollen does not easily fall on the pistil stigma and it is difficult to pollinate, even if the pollination is difficult to form deformed flowers or fall off.
The reasons for the formation of short studs are mainly caused by unfavorable environmental conditions and the nutritional status of the plants. Eggplant is at night with high temperature and low light, and carbohydrates are produced less. However, when it is consumed in large quantities, nutrition can not keep up. Especially when nitrogen and phosphorus are insufficient, organs of flower buds are stunted and prone to occur. Short studs forming malformed flowers or falling off. The preventive measures are as follows:
1. Regulate suitable growth conditions. Eggplant nursery should choose fertile soil. The temperature is controlled at 25°C-30°C during the day, 20°C at night, and the ground temperature is not lower than 20°C. The initial and mid-term attention is to prevent the low temperature, the temperature in the later period is gradually increased, and the high temperature and high humidity are prevented, the temperature difference between day and night is not less than 5°C, and the soil is kept Wet, early flower bud differentiation, long flower buds differentiate quickly, which is conducive to the formation of long column flowers.
Seedling age 70-80 days requires short stems, close internodes, thick leaves, dark green leaves, and more roots. When the seedling grows to 1 leaf and 1 heart, it is transplanted, so that the seedlings are replenished before the flower bud differentiation, and the flower buds are fully differentiated.
2. The method of colonization is correct. One day before planting, the seedbed was irrigated. The next day, the seedlings were lifted with a rake. The eggplant seedlings were brought up with soil and roots were injured as little as possible. After planting, the seedlings were not only quickened but also prevented from falling and causing malformed fruit. Can effectively prevent Verticillium wilt and stale fruit.
3. Strengthen management after planting. After planting, it is necessary to spray flowers on the door with the anti-dropping agent at the right time, which can effectively prevent the production of dehiscent fruits from the protective ground or the exposed eggplant. The cultivation of eggplants in the greenhouses enters the high temperature season, and the shed film should be gradually uncovered to prevent heat damage or produce malformed flowers.
4. Remedy. Once the short stumps of eggplant have appeared, 80 g of phosphorus-potassium power + 15 ml of chlorophyll + 15 g of eucalyptus boron can be used to spray 15 kg of water.
Household Oxygen Generator is a type of machine for producing oxygen, its principle is to use air separation technology. First, the air is compressed at a high density and then the different condensation points of each component in the air are used to separate the gas and liquid at a certain temperature, and then rectify it to separate it into oxygen and nitrogen. In general, people are used to calling it an oxygen generator because it is mostly used to produce oxygen. Because oxygen and nitrogen are widely used, oxygen generators are also widely used in the national economy. Especially Homecare Oxygen Concentrator and Household Medical Devices for hospital and household.
The first countries in the world to produce oxygen generators were Germany and France. The German Linde Company made the world's 10th m3/s oxygen generator in 1903. Following Germany, the French Air Liquide Company also began to produce oxygen generators in 1910. Since 1903, the oxygen generator has a history of 100 years.
