1, timely sowing Sowing in Hubei live before June 15th, if planted as a regenerative rice after the Ching Ming Festival (make sure to plant before April 20) can be planted. The amount of seed used for dry live broadcasting is 4 kg, the amount of water used for live broadcasting is 3.5 kg, and the amount of seed used for throwing acre is 3 kg. After the rice is planted, the soil is sprayed with 33% pendimethalin EC 100-150 ml water 30-50 kg soil spray (acre dose, the drug is mainly used to control annual grass, broadleaf and sedge), soil Closed weeding; three-leaf one-heart period with 10% Hanqiu good EC100 ~ 150 ml (mu dosage, mainly used to control weeds, thousand gold, crabgrass, goosegrass, especially for the prevention of crabgrass, tendon grass performance Especially prominent) + chloroflupiric acid 50 ml (acre, mainly used to control broadleaf weeds) for stem and leaf treatment; in the later stage, weeds can be manually removed. 2. Field management - water Seedling stage: If the soil moisture is insufficient, it should be timely irrigated after sowing to ensure sprouting, prevent emergence of seedlings, large and small seedlings and prolong the growth period due to late emergence. Booting stage: Rice at the booting stage and the stage of filling milk is most sensitive to moisture. It is necessary to ensure that the relative humidity of the soil is above 80% to ensure high yield. 3, field management - with fertilizer The base fertilizer accounts for 70-80% of the total fertilization amount, and the general base fertilizer applies compound fertilizer (N15: P15: K15) 25-30 kg. The field with insufficient soil fertility can increase the amount of fertilization appropriately; Topdressing: 5-8 kg of urea is applied to the jointing stage to the jointing stage. It is recommended not to apply the ear fertilizer. In the later stages, there is usually no need for topdressing 4. Field management - pest control Pay attention to the control of pests such as aphids, rice planthoppers, rice blast, and sheath blight. Before heading, 300 ml (acre dose) of Bacillus subtilis was used to control rice false smut and sheath blight. In particular, rice smut is easy to control, and the whole field is divided into two doses: the first time when more than one third of the whole stalk of the whole field is taken out, that is, when it is commonly called "big package" (from the time of emergence) About 5-7 days), this is the peak of the initial infection of the bacteria. At this time, the drug is used, and the control effect is best. The second time is at the beginning of the rupture, and once again, the drug is used for consolidation. And to improve the control effect, it is recommended to use Jinggangmycin, chlorhexidine, Baoshenning and so on. 5. Water-saving and drought-resistant rice as a regenerative rice planting requires special attention to the following three points: The first is to plant in Hubei before April 20, the second is to keep 35-45cm when harvesting, and the third is to apply two times to regenerate fertilizer (20-30 kg twice).

Depending upon the technical specification of a greenhouse, key factors which may be controlled include temperature, levels of light and shade, irrigation, fertilizer application, and atmospheric humidity. Greenhouse may be used to overcome shortcomings in the growing qualities of a piece of land, such as a short growing season or poor light levels, greenhouses are often used for growing flowers, vegetables, fruits, transplants and seedlings. Greenhouses can be divided into glass greenhouses and plastic greenhouses. Plastics mostly used are polyethylene film and multiwall sheets of polycarbonate material, or PMMA acrylic glass. Commercial glass greenhouse are often high-tech production facilities for vegetables or flowers. The glass greenhouse are filled with equipment such as screening installations, heating, cooling and lighting, and may be automatically controlled by a computer.
