Selection of the membrane, with an o. O. O5mm thick and 170 cm wide monolithic microfilm per 165 cm - 6 lines per crop, with a general usage of 4. 0 kg/666mo on the membrane, in accordance with the impregnated regulation of 9x4 (30cm x 13cm), a fixed hole is punctured and adhesive glue is sprayed around the hole, with a visceral glue that binds the sprouts (breathingly white sprouts) around the pore of the membrane, with 4-5 sprouts per hole. Pre-plantation is preceded by the laying of drip irrigation pipes at the foot of the plume, during which a mechanical membrane is used, followed by pressure on the plume of the adhesive seed on the membrane, followed by drip irrigation at the end of the plume and sustained soil moisture to ensure seeding。
Rice is not inundated throughout its reproductive life, and “sprays” are used to compensate for the amount of water, with membranes covering the soil. Instead of building a layer on the field, when the seedlings return to the ground, they are based on the different long-term needs of the rice, and the normal growth of the rice can be ensured only during the critical period when the rice is most water-sensitive (post-plugging, pharmacizing, gestation, poaching) and the soil is fully watered, while in the other long term the field is only 70-90 per cent of the full water。
In addition to management skills, the following skills components are highlighted:
1 precision. Land mass is required to reach flat ground and the soil is fragmented. Before the whole land, the fertilized farm manure was spread evenly, and hard objects such as rock in the mud, straw, etc., easily broken membranes were collected。
2 the formula is fat. The general average fertilizer field size of 700 kg/667m2 rice grains is based on the following norms: farmer fatty 4000 kg/6 & 7 m2, pure nitrogen 10kg/667m2, phosphorous quinoxide 3kg/667m2, potassium oxide 3kg/667m2. The method of upper fertilizer is the "pre-motion, medium-control, post-preservation" fertilizer method, i. E. Re-enactment of bottom fertilizer to promote early birth and rapid hair, with a medium-term nitrogen to manipulate a reasonable collective, and later filling of nitrogen to prevent decaying seeds。
3 duplicate farming. There is no demand for seedlings and incubation, and the planting period is usually around 10 may。
4 water distribution. After cultivation, depending on the condition of the soil wall, the first drop of water begins, less water is spilled during the sapling period, and in the next four to six days water is usually dripped every four to six days. When the number of saps reaches 80 per cent of the programme's stairwells, it is expected that it will be too strong and early to be closed, and that it will not be tanned for 7 to 10 days, instead it will not tan, it will be wet drip irrigation after 10 leaves, it will be used for dry and wet drip irrigation, it will add oxygen to the soil, and it will promote the root line。
The beginning of the year indicated that the persistence of wetting after the diaphragm resulted in higher yields of 615. 9 kg/hm, with an increase of 56. 9 kg/667m2 and an increase of 10. 18 per cent compared with the production of 559 kg/667m2. Under-paddy drip treatment decreased slightly in comparison. Under-film drip treatment yields 553. 20 kg/667m2, which is 2. 84% less than under-film drip irrigation by 16. 19 kg。
Economic benefits analysis: dry-planted wet tubal rice can have a significant increase in yield, yielding 553. 20 kg of membrane rice and yielding 1991 yuan (input of $575. 00/666m2, output ratio: 1. 3. 4). The yield of rice in the field was 675. 0 kg/667 m2, and the output of 2049 te/667m2, with an output ratio of 1:3. 0. This shows a reduction of $58 for the membrane compared to the single product, but a reduction of $100/267h for the input comparison and a net gain of $42/267m2。
(a) we have more than 40,000 hn? The land is in low-lying and flood-prone areas, and this part of the land cultivates dry wet pipe rice, comparing it with corn and soybeans: soybeans produce 100 kg/667 m2, corn growers produce 400 kg/667m2o, based on a 1-live membrane drip production of 500 kg/667m2, with a total investment of $432/667 m2, with a benefit of $168/667 m2; according to soybeans, 130 kg, 585 dollars
Fta256te/667m2, yielding $329 and yielding $839/666m for rice and soybeans' ; calculated according to monocultured corn production of 500 kg, with a value of $900 and an additional $362/666m' , $538/667m2 and $585/667b more for paddy cultivation than for maize cultivation?, and the economic benefits are significant。
Water scarcity in the spring allows medium- and low-yielding fields to be developed for use and then achieve higher yields. Together, the introduction of dry-planted wet tubing skills can facilitate early pre-maturity of rice so that, in rice-type applications, high-quality late-sprung varieties such as paddy fragrance can be introduced, which is important for high-yield quality rice production in our city。
The use of dry-planted wet pipes, which are regularly dripped according to the demand for rice, avoid unnecessary open drainage and reduce soil leakage and progressive rainfall. Together, weeding is useful in dealing with competitions between rice and weed, avoiding fertilizer loss and evaporation and improving fertilizer use。
