Spring sowing preservation seedlings fixed density
Seed preparation
1. Buy excellent varieties. The selection of high-quality seeds is the prerequisite for guaranteeing the emergence rate, Miao Qi, Miao Quan and Miao Zhuang. Therefore, it is necessary to purchase seeds for the production and operation of large businesses, packaging specifications, good maturity and plumpness, and high germination rates. 2. Chemical seed dressing. Uncoating cotton seeds should be seed dressing. Use 50% of carbendazim WP, 0.5% of seed, 30% of uremic WP or 50% thiophanate-methyl WP of 0.6% seed and 39.1EC or 40% of 75% of seed 0.8% Methylisothiphos EC mixed seed dressing, 2 to 3 kg of water per 100 kg of seed. 3. Sowing seeds. Before sowing, select fine weather and spread the cotton seeds in bags for 2 to 3 days. This can effectively promote the post-harvest use of cotton seed, kill pathogenic bacteria in seed, and increase the seedling emergence rate of cotton seed.
Land preparation
1. Select the land for cotton. It is best to choose a land that has not been planted with cotton or crop rotation. The land that has been replanted for many years must be kept from growing cotton. 2. Level land. It is necessary to deepen 25-30 cm deep to determine the type of cotton to reduce the surface pathogens, which will help the emergence of seedlings. Irrigation should be done in advance so as to avoid excessive watering due to too late watering. The ground temperature is low and it is not conducive to emergence. Before sowing, the land will be ploughed so that it will reach "Qi, Ping, Song, Broken, Net, and Shu." 3. Reasonable fertilization. Improper use of seed fertilizers, especially the excessive use of nitrogen fertilizers and chicken manure that is not fully decomposed can affect the seedling emergence rate of cotton seed. Therefore, fertilization should be applied to the base fertilizer. The manure should be fully decomposed, pay attention to the ratio of N, P and K, and apply P and K fertilizers more. 4. Using plastic film covering technology. Seeding in open field, in case of heavy rain, the upper layer of seed can be compacted, and the germ can hardly penetrate, thus affecting the emergence rate. The mulching film has the functions of increasing the ground temperature, maintaining the soil moisture, and avoiding the danger of heavy rain. Therefore, the mulching technology should be promoted and applied.
Scientific sowing
1. Suitable sowing date. Too early emphasis on sowing in production, not to wait for the average temperature to stabilize at 10°C~12°C and sowing prematurely would result in "early but not fullness". In case of rainy weather, the dual effects of low temperature and high humidity are more likely to cause bad species and rotten buds. When the average temperature on the day is stable at 10°C, the temperature of 5 cm below the membrane can reach 12°C or more. 2. Increase the seeding rate to ensure the total amount of seedlings. 3. The broadcast depth should be appropriate. Cottonseed water is difficult to absorb, and the top soil is weak. When sowing is too deep, the germ is difficult to penetrate the soil layer; when it is too shallow, the seed is exposed to the surface of the soil or the soil around the seed is quickly dried, making it impossible for the seed to absorb enough water to germinate. Cotton seeds germinate and emerge. Therefore, the depth of cotton seed should be suitable, and the mulching film should be 2~3 cm.
According to species, soil strength and planting methods to determine the density, reasonable close planting. Generally, single planting spring cotton varieties have a density of about 3,500 plants per mu, a row spacing of 1 meter, and a plant spacing of 19 centimeters; semi-spring varieties generally have a density of about 4,500 plants per mu, and the row spacing is 15 centimeters; the summer cotton varieties are in fertilizer and water conditions. In the good plots, the density per mu is controlled at about 6,500 plants; the general land mass is controlled at about 7,500 plants; the low-yield parcels are 8,000 to 10,000 plants.
The broadcast of whole seedlings is the basis for increasing yields. In order to reach full-seedling seedlings in production, we must first select higher-quality seeds. Secondly, the necessary seed treatment must be carried out before sowing, such as seed selection and drying, in order to increase the germination rate and the vitality. In order to prevent the disease at the seedling stage of cotton, pesticide seed dressing is also required. Third, we must pay attention to the quality of sowing, adequate enough sowing. The general sowing depth is about 4 cm. In addition, spring cotton should pay attention to the application of base fertilizer, generally more than 5 square meters of organic fertilizer per acre, ammonium dihydrogen phosphate 20 kg.
Corn has a more complete nutritional profile, making it ideal as a preferred food for scientific fat loss.
Generally speaking, sweet corn favors vegetables and sticky corn favors staple foods.
This classification is for the sweet corn (vegetable).
There are generally two ways to lose fat scientifically: exercise and controlled diet. Both are indispensable and must be combined for effective fat loss. Especially for people who are not particularly obese, we should consider the combination of exercise and diet control. In terms of diet control, take care that the daily intake of food is based on high quality protein and vegetables.
1. The time and intensity of exercise should be gradual. Exercise more than 1 hour a day is good.
2. exercise to control their mouths, eat less sugary food. If you are more gluttonous, you can use fruit sweet corn to satisfy your cravings. Fruit sweet corn is sweeter to eat, but it is low in sugar and satiety, which can help you control your diet.
