How to manage rice in the middle of the rice, in the middle of rice growth, farmers should carry out water and fertilizer management on rice, and also need to dry the fields and control pests and diseases to ensure the good growth and development of rice. So how should we manage it? Rice mid-term management four steps 1 After re-watering in the field, according to the growth of straw in the field, it is necessary to apply nitrogen fertilizer to the weak areas. At the same time, the panicle fertilizer is applied during the differentiation stage of the young panicle, and attention is paid to the application of potassium fertilizer. In order to promote the differentiation of the first and second branches; at the same time, the tillers are consolidated and the stems are thick. Moreover, the application of panicle fertilizer can also promote the differentiation of spikelets, increase the number of spikelets, and reduce the lodging caused by the elongation of the lower internodes and upper leaves. Finally, the application of panicle fertilizer can also increase the seed setting rate (rice seed setting rate is an important component of yield, and the effect of seed setting rate on yield is second only to the number of panicles. Increasing the seed setting rate of rice can directly increase the number of grains per panicle and increase rice yield) , increase 1000-grain weight (1000-grain weight is the weight of one thousand grains of rice expressed in grams, in g). What is to be controlled is the time of application of the ear fertilizer. If it is applied too early, it will easily cause lodging; if it is applied too late, it may cause poor differentiation of branches, resulting in less spikes and less yield. The recommended application time varies from the second leaf to the third leaf, depending on the variety. 2 In order to ensure the maximum effect of the drying field, we need to drain the ditch in time. When it is exposed to rain or water during the drying of the field, it cannot function as a drying field. At the beginning of the differentiation of young spikes, the work of rehydration is carried out simultaneously, and there is no shortage of water. It is necessary to ensure that water is available for the successful completion of rice ear differentiation. At the beginning of heading, the field should establish a submersible layer to ensure the growth needs, while increasing the humidity in the field; after drying, the dry and wet alternates to ensure the water needs, improve root activity, leaf photosynthesis, seed setting rate and grain weight. In the field with strong water and fertilizer retention capacity, water can be cut off at half time of filling and easy to harvest. For the second mud field, water is cut off two weeks before harvesting, and Shatian is cut off one week before harvest. 3 The role of drying the field is to change the physical and chemical properties of the soil, adjust the plant's longitude, promote the development of roots, and inhibit the ineffective tillering in the later stage. It can also control the growth of the lower leaves and internodes, delay the root senescence, increase the seed setting rate, reduce the plant height, and enhance the lodging resistance. When drying the field, observe the local conditions, observe the five points of soil quality, seedling number, leaf color, growth and fertility. If the soil is sticky, the number of seedlings is sufficient, the color of the leaves is strong, the growth is strong, and the fertility is high, then it is necessary to expose to the sun and heavy sun; on the contrary, it is to achieve late sun and light sun. 4 The pest control during this period should also be synchronized. The prevention and control of rice sheath blight and aphids should be observed in time and treated in time to avoid causing more losses. The above is the management point of rice in the medium term. In general, rice wants high yield, and can not be ignored in each growth period, and relevant measures are taken to make high-yield later. Soy lecithin powder is a substance derived from soybeans that is commonly used as an emulsifier, stabilizer, and thickener in food products. It is a natural source of phospholipids, which are essential components of cell membranes. Soy lecithin powder is often added to chocolate, baked goods, and other processed foods to improve texture and prevent separation of ingredients. It is also used in the production of dietary supplements and pharmaceuticals. Soy lecithin powder is generally considered safe for consumption, although some people with soy allergies may need to avoid it.
