After the early rice planting in this year, the southern part of the country fell to heavy rains for many days, and many places suffered floods. After the rice is flooded, its growth and development is affected. The "water damage" is obvious. Strengthening the management of fertilizer and water is an important measure that can not be ignored after the flood disaster. The following tasks should be done: rapid drainage and shortening the flooding time. To eliminate internal or stagnant water, you should quickly concentrate manpower and material resources to rush to eliminate the flooding time.
However, it should be noted that the method of elimination should not be rushed to drain. At first, the shallow water layer should be maintained, and then drained gradually to avoid the decline of the root activity of the rice after the mites, the water absorption capacity is weakened, and the rice is caused by the rain after the rain. The plant is physiologically dehydrated and the leaves are withered, which in turn aggravates the loss;
Moreover, it is beneficial to soil ventilation and early recovery of root activity. Washing leaves and seedlings to wash seedlings and decontamination are beneficial to the rapid restoration of photosynthesis. For the flooded early rice fields, the sludge on the rice leaves should be washed with water, and the plants that have fallen down must also support the seedlings. When the weather suddenly turns fine after the rain, the general temperature rises quickly, and the paddy fields must be flooded in time to prevent the loss of water and dead seedlings. When you support the seedlings, you should avoid breaking the roots and hurting the leaves.
After strengthening the water management and drainage, on the basis of the gradual solidification of the paddy fields, the fields with short flooding time and relatively high number of seedlings will be lightly placed 2 to 3 times; for the wetlands with heavy disasters and insufficient number of seedlings, First, the field is exposed, and then it is lightly laid, so as to help the growth of early-stage tillers and protect the future tillers. Later, according to the characteristics of the high-level flooding of the flooded early rice and the different growth schedules, special attention should be paid to strengthening the post-management, striving for the growth and consistency, and playing the group. Increase production effect.
After the application of the restored fertilizer, the absorption capacity of the early rice roots is weakened. It is not suitable for one-time heavy fertilization. The fertilizer can be applied once after draining the exposed field. After 5-7 days, the fertilizer is applied again. The nitrogen fertilizer is the main one, and the urea is generally used per mu. 5 kg, compound fertilizer 20 kg; 15 days to see the second application of seedlings, the main fertilizer, with phosphorus and potassium compound fertilizer.
For the field after the flooding, the seedlings are late, the basic seedlings are insufficient, or the dead seedlings have appeared, the fertilizer should be applied as soon as possible and re-applied once, and 7.5 kg of urea or 20 kg of compound fertilizer per acre. Later, according to the condition of the seedlings, the flower fertilizer and the flower-preserving fertilizer are promoted, and after the heading, the root dressing is appropriately carried out. For the later stage of the fertility process, Huimanfeng and potassium dihydrogen phosphate can be sprayed at the beginning of the earing stage to promote the tidying of the heading, enhance photosynthesis, and increase the seed setting rate and 1000-grain weight.
Strengthening pest control After rice is flooded, the disease resistance of plants is reduced, and the microclimate environment with high temperature and high humidity is easy to form in the field, which is conducive to the occurrence and spread of pests and diseases, and is easy to cause bacterial brown streak and bacterial blight. Diseases, therefore, we must adhere to reasonable water control, tube fertilizer, especially in the late growth stage of early rice, to do shallow water irrigation, control nitrogen fertilizer, appropriate application of phosphorus and potassium fertilizer to enhance plant disease resistance.
It is necessary to spray and control the old ward and the flooding early rice fields with bacterial blight and bacterial brown streak at the beginning, using 20% ​​leaf green double wettable powder 100-150 grams per acre and 50 kg spray with water.
When the weather turns sunny and the temperature rises, special attention should be paid to the prevention of sheath blight. Generally, 150 g of Jinggangmycin per acre can be used, and 50-60 kg of water can be sprayed. Insect pests mainly include rice planthoppers, rice leaf roller, and other pesticides, which can be controlled by pesticide sprays such as insecticidal double and leaf mites. Pay attention to the prevention and control of rice blast in the later period. (Cao Lijun)

Cosmetic ingredients are too broad a range. Our industry is usually divided into: 1. Basic ingredients, water or oil The main basic ingredients of general skin care products are distilled water or purified water, oil is vegetable oil or animal oil or mineral oil, according to the form of oil: liquid oil, semi-solid fat, solid wax. 2. Added ingredients, functional ingredients or control and adjustment ingredients Functional ingredients are mainly moisturizing, whitening, anti-aging, acne and other effective ingredients, according to different processes, plants as extracts, other organisms as extracts. Control components are preservatives, antibacterial agents, thickeners, emulsifiers, flavors, pigments and so on. Preservatives ensure that the product will not rot and deteriorate, antibacterial agents ensure that the product will not be infected by fungi, thickener to adjust the viscosity and flow variation, emulsifier to determine the product evenly dispersed into another substance, essence and pigment to ensure the stability of product smell and color. So, I don't know if that's what you want to know? Or do you want to know the names, the structures, the properties of the various monomer components, and if you want to know about that you can go to the INCI directory and Cos Dna for details
