Grab early sowing: After flooding, accelerate the organization of the allocation of provenances, select the early rice varieties with a growth period of 90 days to 100 days, and direct and direct seeding and transplanting. According to the 80% safety rate, the seedlings will be planted before July 20th; the live water will be planted before July 25th and germinated before sowing to ensure that there are no lost fields. Reasonable dense planting: The rational and close planting of the panicles is the key to changing the level of rice production. Direct seeding amount of rice fields per acre is controlled at 8-12 kilograms and basic seedlings are 200,000-250,000; seedlings are transplanted into 40,000-50,000 holes per acre, 4-6 seedlings per acre, and 200,000 yuan per mu are ensured. Seedlings to ensure the formation of a suitable number of spikes. Early fertilization material: the use of "a bomber" fertilization method, in the late control of fertilizer, in order to prevent late maturity. The entire growth period applies 7.5 to 10 kg of pure nitrogen per acre. Generally, fertilization is applied at the 4th to the 5th leaf stage, and the fertilization is controlled in the middle period, and the extra-root topdressing is appropriate in the later period. Reasonable irrigation: Live water, serious soil preparation before sowing, the plot before the seedlings do not leave water layer to prevent boiled buds. After the seedlings were established, the water layer was gradually established. Before the 5th leaf stage, the soft-rest was 2 to 3 times. After the 5 leaf stage, the water was intermittently irrigated and 7 days before the maturity. The use of gibberellin: to change the late rice maturation, heading temperature is low, in order to prevent heading is not neat, there Baonuan phenomenon, to 20% when the head spraying 1 g per acre gibberellic acid, promote heading and tidy. Prevent pests and weeds: Adopt comprehensive measures to prevent pests and weeds, focus on prevention and control of early weeds and rice thrips, mid-stage sheath blight, rice leaf roller, and late rice planthoppers. Glass Venlo Greenhouse is Spire-type glass design, design and installation of windows when more convenient and easy.

In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. the steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using 4 mm thick float glass.
Flooded paddy field replanted early rice technology
In the flooded rice fields, early rice varieties with short growing period can be replanted within the appropriate period.
