I. Demonstration method: All areas are equipped with simple plastic tray seedlings, and the varieties are Jixi 88.
1. The transplanting method in the treatment area is north-south and north-west, 19-20o westward, 50 lines wide, 20 lines narrow, and 13 lines long;
2. The transplanting method in the control area was the same as that of the pond, with a 27-33-inch row spacing and 13 rows of normal transplants.
2. Demonstration Results and Analysis: From the growth and development status of rice individuals, it was shown that the stem diameter and individual tillers of high light efficiency rice seedlings were better than those of conventional transplant methods; resistance, such as lodging resistance and resistance to sheath blight In the field of rice blast resistance and other aspects, no occurrence of lodging and disease occurred in the high light efficiency area; from the perspective of economic traits, rice in the high light efficiency area showed advantages such as large spikes, many grains, increased maturity, and increased yield. Questionnaire. As can be seen from the table, the maturity of rice in the high light efficiency area is 3-4 percentage points higher than that of the conventional transplanting method; the high light efficiency area of ​​rice yield is 15-24% higher than that of the conventional transplanting method. In summary, due to the full use of light energy in rice high-efficiency cultivation techniques, rice has enhanced ventilation and light transmission capabilities, and has played an advantage in rice sideways, which in turn demonstrates the individual developmental advantages of rice, the coordinated development of the population, and ultimately rice grain. Full, balanced purpose of production increase.
3. Conclusion: The application of rice high-efficiency cultivation techniques in five townships with different production conditions and production levels in our city shows that this technology can improve the growth and development conditions of rice and promote the healthy growth and coordinated development of rice individuals. If supplemented by the selection of high-quality, high-resistance, strong ability to produce tillers, high-yielding and large panicle type varieties, and using plastic tray seedlings or other dry nursery methods to cultivate the two major technical conditions of dry and strong, it can greatly increase rice yield and increase yield. The amplitude can be more than 15%.
Food additives refer to chemical synthetic or natural substances added to food for the purpose of improving the quality, color, aroma and taste of food, as well as for the need of preservative and processing technology. Due to the rapid development of the food industry, food additives have become an important part of the modern food industry, and has become an important driving force of technological progress and technological innovation in the food industry. In the use of food additives, in addition to ensuring their due function and role, the most important thing is to ensure the safety and health of food.
