Technical points of middle rice seedlings

1, Putian choice. Putian should choose leeward sunny, flat terrain, irrigation and drainage is convenient, not susceptible to flood, clean water, less weeds, soil and sandy fields. Putian made 1.5 meters wide, 0.25 meters wide, and 0.15 meters deep. Apply 50 kg of compound fertilizer per acre to make the base fertilizer. When sowing is required, it should be flat, soft, and fine, with a layer of floating mud on the surface to facilitate the sticking of seeds. .

2, seed processing. Before sowing, choose sunny sun-dried seeds for 3 to 4 hours, and then use it to cool in a dry and cool place. Pour the seeds into clean water, stir well, and remove the fish floating in the water.

3, soaking. After draining the washed seeds, they are pre-soaked with fresh water for 12 hours, then 300 times 40% trichloroisocyanuric acid (strong chlorine) wettable powder solution for 10 to 12 hours, washed with water. After germination can be sown.

4, germination. The washed seeds are put in a woven bag and put in warm water at 40-45°C for 5-6 minutes. Before the seeds are loaded, first prepare the baskets, and then place a 10 cm-long disease-free rice straw in the baskets. Before the seeds are warmed up, soak the straw with boiling water, and put the preheated seeds that have been drained into the bowl. On the straw or sack, promptly wrapped with agricultural film, put in the haystack and incubate, warm water of 35°C every 3~4 hours, when the grain itself heats up, the temperature is controlled at 35~38°C, over 40°C. Turn the heap in time and mix the upper and lower parts of the seed with the inside and the outside thoroughly. After 20 hours, expose the white and break the chest. After the seed is broken to 80%, the seed is poured into warm water once and the temperature is adjusted to the optimum temperature of 25-30°C. Germination and rooting, when the shoot length is 1mm, the seeds are allowed to stand and dry for 4 to 6 hours until the water is not sticky.

5, precision seeding. Hand-planted Putian and Daejeon ratio 1:20 ratio to stay in Putian; machine inserted Putian and Daejeon 1:100 ratio to stay in Putian. There are two kinds of artificial sowing and mechanical sowing, artificial sowing need to sow back and forth 3 to 4 times until uniform, after sowing covered 0.5 cm fine soil. Subsequently, 2m long bamboo pieces were arched on both sides of the pole to cover a 2m wide agricultural film.

6. Putian management. At the seedling stage, the heat preservation and moisturizing were the main factors. Before the three-leaf stage, the water was kept moist and not white. After the three-leaf stage, the ditch was drenched and the water was controlled for three days before transplanting. 1 leaf 1 mu with 15% paclobutrazol wettable powder 120g, spray 60kg water, 2 leaf 1 heart rate with urea 5kg, water 500kg pouring. Machine insertion age control in 20 days, the longest not more than 25 days; leaf age 3 leaf 1 heart or 4 leaf 1 heart, seedling height of about 20cm is the most suitable machine inserted. If the seedlings are too long, they should be cut off.

Moisturizing Raw Materials

Moisturizing is the foundation of skin care. The basic skin care products that are indispensable for moisturizing and hydrating such as lotions, lotions and essences, how in the end should I choose the real moisturizing products? The easiest way is to look at the active ingredients of the product. Common Cosmetic Ingredients series, common moisturizing ingredients, let's take a look.
1, glycerin, the scientific name of propanetriol, glycerin can be classified as a natural ingredient moisturizer, mild texture, not easy to cause skin allergies, etc.. But glycerin itself is only moisturizing and no skin care function, so it works well for young, healthy skin. If the skin needs multifaceted maintenance, then the maintenance products also need to contain other effective ingredients and glycerin with the use.

2, collagen, collagen on the skin care although important, but its due to the molecular large, directly applied when not accepted by the skin. The real improvement of the skin collagen content is the use of collagen boosters, such as vitamin C, vitamin B3, vitamin A.

3, hydrolyzed collagen, hydrolyzed collagen is the large molecule of collagen to hydrolyze the processing into a small molecular weight of protein. The hydrolyzed protein is not as good as other moisturizers in terms of pure moisturizing effect, but has a certain function of improving skin texture. When you are shopping, make sure that the collagen in the maintenance products is labeled "hydrolyzed collagen", which is the collagen that can be absorbed by the skin. The actual fact is that you can find a lot of people who are not able to get a good deal on this kind of things.

4, amino acids, amino acid moisturizing mechanism and other moisturizers are different, it does not have a strong water absorption, but the skin moisture has a regulatory role, because the moisture content in the stratum corneum is reduced, the amino acid content at the same time reduced, so the maintenance products in the addition of amino acids is necessary to maintain the normalization of keratin function, but amino acids do not belong to the "main moisturizing factor "The main factor is the fact that it is not the main moisturizing factor.

5, natural moisturizing factor, the main components of natural moisturizing factor are amino acids, sodium lactate, urea, etc.. In pure moisturizing effect is not as good as glycerin, but because of its good skin-friendly, can regulate the skin pH function and maintain the normal operation of the keratin, not only has a moisturizing function, but also a certain maintenance function, is also indispensable moisturizing ingredients.
