The formation of large rice spikes is an important goal in agricultural production, which not only affects the yield of crops, but also has a direct impact on the quality of rice. Through scientific cultivation and management measures, the formation of rice panicles can be effectively improved, so as to improve the yield and quality of rice. In this article, we will detail how to improve rice panicle formation through cultivation management measures.
1. The importance of rice panicle formation.
The formation of rice panicles is an important stage in the growth process of rice, which is of great significance for increasing rice yield and improving rice quality. In agricultural production, increasing the formation of large rice ears will help increase farmers' incomes and promote the development of agriculture.
2. Key factors affecting the growth of rice and the formation of large panicles.
1. Variety selection: There are differences in the growth characteristics and yield of different rice varieties, so the key to achieving high rice yield is to select varieties suitable for local planting, strong drug differentiation, high panicle formation rate and large number of grains per panicle.
2.Sowing density: Sowing density also has an important impact on the growth and yield of rice. Too high sowing density will lead to fierce competition between plants, slender stems and weak seedlings, easy to plant injury, large slow seedlings after planting, slow regreening, late separation, affect photosynthesis and nutrient absorption, thus affecting the formation of large spikes.
3.Fertilization level: Fertilizer is an important nutrient for rice growth**, insufficient or excessive fertilization will affect the normal growth of rice, and then affect the formation of large spikes.
4.Irrigation conditions: Suitable water conditions are necessary conditions for rice growth, too much or too little water will affect the normal growth of rice, and then affect the formation of large spikes.
3. Cultivation management measures.
1. Variety selection: According to the local climatic conditions and soil characteristics, select suitable varieties to ensure that the varieties have the characteristics of strong drug separation power, high spike rate and large number of grains per spike.
2.Planting density: Determine a reasonable planting density according to the characteristics of the variety, ensure good ventilation and light transmission between plants, which is conducive to photosynthesis and nutrient absorption, shallow cutting, and quantitative planting of basic seedlings. Promotes large spike formation.
3.Fertilization management: according to soil fertility and rice growth needs.
Seek to develop a reasonable fertilization plan. Pay attention to the balanced application of nitrogen, phosphorus, potassium and other elements to avoid excessive fertilization leading to premature plant aging.
4.Irrigation management: According to the rice growth stage and climatic conditions, the irrigation time and water volume should be reasonably arranged. Sensitive in moisture.
During the susceptibility period, attention should be paid to maintaining suitable water conditions to prevent too much or too little water from affecting the formation of large spikes.
Fourth, the operation methods and skills.
1.Seeds are selected and treated before sowing to improve the germination rate and disease resistance of seeds. It is suitable for sparse sowing and cultivating robust seedlings, which is conducive to rejuvenation, early growth and rapid development.
2.Reasonable dense planting, according to the characteristics of the variety, reasonable dense planting is conducive to the advantages of the characteristics of the variety.
3.In the process of fertilization, pay attention to the combined application of organic fertilizer and chemical fertilizer to improve soil fertility and soil structure.
4.In the irrigation process, water-saving irrigation technology is adopted to reduce the waste of water resources.
5.In the process of pest control, pay attention to the combination of biological control and physical control, reduce the use of chemical pesticides, and improve the stress resistance and lodging resistance of plants.
6.Timely and appropriate application of growth control agent, calcium cyclic acid, multi-effect.
azole, uniconazole, arthromine and other growth control agents. In order to avoid excessive and late application, the amount of rice spikelets will be reduced, which will affect the formation of rice panicles.
5. Optimize the soil environment.
The quality of cultivated land can be improved and promoted through soil improvement, microbial community regulation and nutrient supply optimization.
The plant grows healthily. For example, straw returning technology is used to increase soil organic matter content;Rational crop rotation system to improve soil microbial community structure;precision fertilization technology to improve nutrient use efficiency, etc. These measures help to create a good soil environment and provide strong support for the formation of rice panicles.
6. Pest control.
Attention should be paid to pest control in the process of cultivation management. By strengthening field investigation and forecasting, timely detection and effective measures are taken to prevent and control the occurrence and development of pests and diseases. At the same time, the use of biological pesticides and high-efficiency, low-toxicity and low-residue chemical pesticides should be promoted, so as to reduce the impact on the environment and the quality of agricultural products, and improve the stress resistance and lodging resistance of plants.
7. Case analysis.
For example, in actual production, a small number of rice farmers have adopted improved varieties and good methods, and carried out scientific and reasonable fertilization and irrigation management measures during the critical period of rice growth, which effectively improved the formation of rice panicles, increased yield and quality, and also reduced production costs, and achieved significant economic benefits. These successful cases provide planting experience for other rice farmers to learn from, and provide strong support for the promotion and application of scientific cultivation management measures.
Sum up. Through the implementation of effective cultivation and management measures, the formation level of rice panicles can be improved, and then the yield and quality can be improved, the production cost can be reduced, and the environmental awareness and relevant policies and regulations are in line with the requirements of environmental awareness and relevant policies and regulations, which is of great significance for promoting agricultural development and improving farmers' income, and is also in line with the requirements of the national agricultural sustainable development strategy, so it is worthy of widespread promotion and application in agricultural production.
