Is it difficult to grow bitter gourd and fertilization? Recently, many friends have asked about the bitterness of loofah. They said that they bought bitter gourd. The question is whether it is caused by improper fertilization in loofah cultivation. In fact, not only loofah, research shows that cucumber Melons, melons and other melons will also become bitter. Qian Health, an associate researcher at the Zhoukou City Academy of Agricultural Sciences, published the "Causes and Control Measures for the Bitterness of Melon Vegetables" in the May 2011 Agricultural Science and Technology Newsletter. This article pointed out that the roots of most melon vegetables are broad and transpiration. Exuberant, insufficient or too much water, is not conducive to the growth and development of melons, easy to appear bitter melon. For its original reasons, many experts and front-line technicians have different interpretations, among which varieties, climate and fertilization are three recognized factors. Yang Si, a professor at the Department of Vegetable Science at South China Agricultural University, said that the bitterness of leafy vegetables such as Caixin and Shanghai Qing is also related to partial application of nitrogen fertilizer, spraying and climate. Luo Yongqiang, general manager of Guangzhou Xianpin Agricultural Co., Ltd. has done relevant tests to show that in the autumn when the rain is less, the loofah is prone to poor growth due to factors such as high temperature and drought, which changes its taste. In addition, pests and diseases are also the factors that induce it to become bitter. one. He analyzed that Cantonese people like to eat angular loofah, which is thicker, chewing pests rarely eat, but sucking (such as needle) is very preferred. According to reports, stimulated insects absorb the melon juice, it will trigger the physiological reaction of the crop to secrete bitter substances. In addition, in the southern region, if the melons are sucked into the eggs by the needle bee insects, the taste will be bitter. Luo Yongqiang found that there is another possibility due to the change in the taste of melons caused by the variety. He said that if the loofah is mixed with wild water melon to cause skein, it will make the former bitter. Hu Xinjun, an associate researcher at the Hunan Vegetable Research Institute and a loofah breeding expert, believes that loofah will suffer from the cucurbitacin it contains. He said that loofah contains a hidden gene that controls bitterness and is expressed under certain environmental conditions (drought, high temperature, etc.), causing some loofah varieties to become bitter. "If a loofah variety has a wide range of bitterness, the variety may need to be improved." In addition, Qian Health also believes that melons use fruit as a product, and fertilizer has a direct impact on its quality. If the application of nitrogen fertilizer is too much, it will cause the plants to grow up, the melons are not neat, and the melons on the side branches and weak branches are easy to bitter. At the same time, excessive application of nitrogen fertilizer, or insufficient phosphorus and potassium fertilizer is also prone to bitter melon. In addition, calcium is an essential element for melon carbohydrate synthesis and for increasing its sugar content. The application of organic fertilizer is the key to avoiding suffering. The safety of bitter gourd has not been verified. Many growers have found that different parts of melons have different levels of bitterness, and usually the bitter taste is higher. Liang Shujun, a researcher at the Vegetable Research Institute of the Guangdong Academy of Agricultural Sciences, explained cucumber as an example. The content of cucurbitacin in the fruit stalk is relatively strong, so the bitterness is biased. At the same time, this bitterness can be passed on to the next generation through the seeds. Since there are many factors that can cause melons to become bitter, how can we manage to avoid the emergence of "all the melons and bitter melons"? How to apply organic fertilizer and use less fertilizer is a common prescription prescribed by experts. Tang Bingsheng, a vegetable farmer from Longcheng County, Heyuan, is a typical example of insisting on planting loofah with farmyard manure. He introduced that fish manure and sludge are used as loofah fertilizer every year. In addition, in order to supply organic farmyard manure as a base fertilizer, he also deliberately went to the local Chinese medicine factory to pull the remaining dried grass, add turf to dry and burn together as soil to put the base fertilizer into the melon hole, and then cover the soil and drench the water. Regarding the above practices, Hu Xinjun believes that ordinary farmers cannot copy because of technical, labor and cost issues. However, he suggested that the base fertilizer applied by the growers can be mainly organic fertilizer (farm fertilizer), combined with the application of compound fertilizer, and topdressing with optional water soluble fertilizer. At the same time, it also pointed out that topdressing should be done a small number of times in order to fully absorb. An expert from the Research Institute of Vegetables in the Guangdong Academy of Agricultural Sciences reminded farmers to pay attention to planting the corresponding varieties at different sowing dates. "Can the bitter melons be safe to eat?" is the key to affecting the sales of growers. Zhang Feng, a senior agronomist at the Beijing Vegetable Research Center, said that the cucurbitaceae plant contains common cucurbitacin, which itself has a bitter taste and has little effect on the human body after consumption. However, Hu Xinjun does not agree. For example, the bitter-sweet loofah has not been tested in China for its safety, and it is therefore impossible to determine whether people will be harmful after eating. "The bitter melon (except bitter gourd and other bitter melons) is mostly of poor quality and low nutritional value. It is recommended not to eat."
