Mechanical laminating technology is to raise preservation of soil moisture of ground temperature, fight a drought between soja travel, maintain fireweed of fat, control, improvement character, raise the agriculture machinery with a kind of crop, very remarkable synergism that reduces manufacturing cost to change new technology. The laminating between soja travel helps advance somebody's career new technology is used " smooth sow the laminating between travel " method, going up one year namely autumn on the foundation of soil preparation, fertilization, choose high grade and appropriate breed, flat to sow not ridging ridging plough, use 6 next or machinery of 8 soja laminating is ground film Fu between seedling belt and seedling belt, is not to be enclothed directly go up in seedling belt, easy operation, practical strong. The main characteristic of this technology is sow outside the fertilization inside film, film, prevent chemical fertilizer to volatilize, raise chemical fertilizer utilization rate, moisture is in from velar edge inside the film that take a person, prevent moisture to evaporate, be helpful for preservation of soil moisture. Use this technology, can make edaphic temperature rises 3, 5 ℃ , increase to be accumulated effectively lukewarm 300 ℃ left and right sides, fertilizer utilization rate raises 10 ％ above, soybean per unit area yield raises 30 ％ left and right sides, protein content raises 2 ～ 3 percent, adipose content increases 1.2 percent.
One, the technical point of mechanical laminating between travel
1. Thoroughbred choose. Choose admirable breed, requirement seed purity achieves 98 ％ above, spend completely achieve 97 ％ I. X~ , gemmiparous rate achieves 95 ％ above, the seed wraps garment rate to achieve 100 ％ , assure seminal quality.
2. Soil preparation. Deep loose deepness achieves 25cm above, plot should be rectified smooth rake fine, accord with sow, laminating requirement, ensure machinery works quality.
3. Sow, fertilization. Choose water of high grade happy event to be fond of fertilizer to be planted formerly, every hectare application rate 55 ～ 66kg, every hectare uses phosphoric acid 50kg of 30kg of 120 ～ 150kg, urea, potash fertilizer does 2 ammonia base fertilizer. The seed uses kind of clothing medicine to include the clothes, after sowing, close destroy careless.
4. Laminating. Use film of 800mm wide ground, film is deep 0. 008n1Hl, the width after laminating is 600 ～ 700mm, fertilization position is controlled in the 50mm inside velar edge, from the place side film 50mm sows, ground film wants clingy floor, velar edge builds earthy rigor, ground film connect is in and
Place having opening must press rigor with earthy lid.
5. Ill Chinese caterpillar fungus of prevention and cure is killed. Adopt integrated technique, make area of prevention and cure of disease of disease of soja grey spot, the bug that eat a heart achieves 100 ％ . Weed in chemistry respect, insist to be given priority to with processing of Miao Qian soil, with leaf of the bine after the seedling processing is complementary, do not use drug of any tall remain chemistry, achieve allow without mark of social effects of pollution, green.
6. Field managing. Laminating soja from a series of production segment that sow results, want to organize personnel to undertake detecting recording.
7. Results. Execute sheet to close, sheet is taken off, odd store, only treatment, ensure soja of the laminating between travel improves grade, ensure the purity that serves as a seed and quality.
2, the machines and tools that the laminating between soja travel uses
Machine of the laminating between soja travel basically uses Heilongjiang to save machine of laminating of the 2MFB-4A that limited company of machinery of tender river agriculture produces soja, this machine is with " face of ridge in a field helps advance somebody's career and the laminating between ridge in a field " two major composition, can make the same score sow the laminating between 4 8 ridge in a field, ridge in a field.
3, effect analysis
The laminating between soja travel helps advance somebody's career mechanization technology and convention cultivate soja photograph to compare, advantage body now " 4 little, 3 tall, keep balance " on.
"4 little " include: ① seed investment is little. As a result of the improvement of edaphic moisture, make rate of soja keep a full stand of seedlings rises, individual growth is better, can decrease 25% what sow a quantity. ② weeds expense is little. Soja laminating helps advance somebody's career is undertake closing handling destroying before sow careless, if be outside film reappear farmland running to weeds, it is normal to be used only spray with belt of the seedling outside measuring the herbicide of 40% to use film can. Expenses of ③ machinery operation is little. Soja laminating does not need ridging ridging plough, suppress, reduce intertill number. ④ artificial investment is little. After laminating, absolved weed artificially, artificial investment decreases relatively, increased in time to uncover velar link, every hectare also will little investment 30 yuan.
