Both paclobutrazol and chlormequat are endogenous gibberellin synthesis inhibitors, which have the effects of delaying plant growth, inhibiting stem elongation, shortening internodes, promoting plant tillering, and increasing plant resistance. It is commonly used in production to reduce the height of rice and wheat plants in order to prevent lodging. However, it has been found in practice that the improper use of these two drugs often causes adverse effects.
Because paclobutrazol can be used as a strong scorpion agent, the seedlings have a short, strong appearance, a rich green leaf color, and a well-developed root system. Farmers often spray paclobutrazol when they see excessive growth of rice and wheat seedlings, although they can temporarily reduce the strains. High, but can easily lead to an increase in the number of invalid childbirth, and according to the theory of plant physiology and metabolism, can easily lead to the rebound of rice plant height in the late period, but reduced the lodging resistance. According to surveys, the application of paclobutrazol and chlormequat at the jointing stage of rice and wheat can reduce the plant height and increase the lodging resistance, but it can affect the spike parting and development, resulting in a decrease in the number of grains per spike and a thousand grain weight. In the late rice and wheat, there is no lodging. The situation often results in a reduction in yield, which means that the application of these drugs on rice and wheat guarantees stability, but it is not effective for high yields.
In addition, when paclobutrazol is used in too large concentrations, it may cause problems such as neck and heading difficulties in rice and wheat. However, improper application of chlormequat in wheat may cause severe stunting, malformation, stalk bending, and spikes in wheat fields. Can not pull out, leaf shrinkage and other abnormal conditions. Paclobutrazol is not easy to decompose in soil and has a long residue period. The United States, Japan, and Europe have banned the use of food crops in the later period. Therefore, it is recommended that paclobutrazol and chlormequat should not be used arbitrarily in the production of large-area rice and wheat, otherwise improper use will not be conducive to high yields.
The yellow mealworm is not only rich in protein, fat, polysaccharid and other organic macromolecular nutrients, but also rich in phosphorus, potassium, iron, sodium, aluminum and other trace elements. For every 100g of the yellow mealworm larvae, the protein content of dry powder is between 48% and 54%, the fat content is between 28% and 41%, and the contents of vitamin E, B1 and B2 are also high. Therefore, the yellow mealworm can provide high quality protein for birds, make birds strong, eyes bright, feathers rich and shiny.
