Every year in the autumn and winter seasons, vegetable farmers always report that the tomato fruits in the shed are "ribbed", which are hollow fruits, with low yield and poor quality. The occurrence of this situation has a lot to do with the weather and improper cultivation management. cause There are many reasons for tomato hollow fruit, such as excessive use of nitrogen fertilizer, continuous rainy weather, insufficient light, reduced photosynthesis, insufficient nutrients inside the tomato fruit, easy to produce hollow fruit; during the flowering period of the tomato, if the temperature in the shed exceeds 36 The temperature lasts for a long time, pollen is poorly fertilized, and the cells of the pulp tissue during fruit development are not coordinated with the growth rate of the fruit, which will form hollow fruits. In addition, if the supply of fertilizer and water is insufficient during the tomato fruit setting period, the concentration of anthers is unreasonable, which may easily lead to hollowness. The formation of fruit. Precaution Control the temperature difference between day and night: in early winter, the temperature difference between day and night is widened, but the temperature is not low in the deep winter. The light is strong around noon in fine weather, and the temperature in the shed is high. Vegetable farmers should pay attention to maintaining the temperature difference between day and night to avoid high night temperature and causing plants to appear Lengthen, reduce the flow of nutrients to the fruit, and then produce hollow fruit. After entering the fruitful period, the night temperature should be controlled at about 15°C, which can be adjusted by adjusting the air release time and the release time of the insulation quilt. Reasonable use of fertilizer: After the tomato enters the flowering and fruit-setting period, it is necessary to appropriately control the amount of nitrogen fertilizer and increase the amount of potassium fertilizer. Potassium can promote the synthesis and transportation of sugar, and promote the transportation of nutrients to the fruit, which can not only increase the weight of the fruit, but also make the fruit taste Good, bright color, reduce the occurrence of hollow fruit. In addition, proper boron and calcium fertilizer should be added to the leaves during the flowering and fruit setting period of the tomato to increase the fruit setting rate. Don’t be greedy for more fruits: If there are more fruits in the first few panicles, it will easily lead to insufficient nutrients in the next panicle fruits and more hollow fruits. Therefore, in terms of fruit retention, it is recommended that vegetable farmers keep the fruit reasonably according to the growth of the plants in their shed and the nutrient supply. Generally, there are 2-3 first ear fruits of tomato, and 3-4 per ear afterwards; in the early stage, there are appropriate few to cultivate strong trees; the weak ones are appropriate to leave less, promote plant rejuvenation, and ensure the quality and yield of fruits in the middle and late stages. Of course, if the tomato is growing more vigorously, you can also take early fruit retention to control the tree, but you must grasp the degree and immediately remove it after reaching the goal. Avoid too much fruit, and the probability of hollow fruit will greatly increase, which will affect the yield. And benefits.

Black tea (dark tea) is named after the black appearance of the finished tea. It is one of the six major tea groups and is a post-fermented tea. The main production areas are Guangxi, Sichuan, Yunnan, Hubei, Hunan, Shaanxi and Anhui. The traditional black tea is made from high maturity black wool tea, which is the main raw material for pressing tightly pressed tea.
The yellow powder in black tea is commonly known as golden flower, a beneficial microorganism, the so-called golden flower, is in the processing of raw materials through the flowering of this special procedure, specifically in the black tea bricks to cultivate a kind of coronary aspergillus substance called coronary scattered cystic bacteria, commonly known as the golden flower, observed under the microscope, each individual golden flower is umbrella-shaped clusters, the whole body is golden and eye-catching, ringed into a group, evenly distributed.

The process of making black tea generally includes four steps: killing, kneading, stacking and drying. Black tea is mainly classified as Hunan black tea (Fu tea, Qianliang tea, black brick tea, Tri-tip, etc.), Hubei green brick tea, Sichuan Tibetan tea (border tea), Anhui Gu Yi black tea (An tea), Yunnan black tea (Pu'er tea), Guangxi Liubao tea and Shaanxi black tea (Fu tea) according to geographical distribution.
