Description
Technical field
The present invention relates to field of agricultural production technologies, be specifically related to beet and be completely cured device and using method thereof.
Background technology
The important zonal specialty economies crop of northern China agricultural is not only by beet, the primary sugar material resource of Ye Shi China except sugarcane.The development of beet production and sugar industry, all can have a direct impact Region National Economy and people's lives.The every Annual planting area of whole nation beet about 300,000 hectares, there are the ground such as Heilungkiang, Jilin, Inner Mongol, Xinjiang major production areas, and wherein maximum with producing region, Heilungkiang cultivated area, every annual sowing area accounts for more than 50% of national beet sowing area.Heilongjiang area falls sharply in recent years, and annual sowing area have decreased to about 100,000 hectares, and per unit area yield only has 17t/hm
2left and right, locates national each producing region floor level, even if also only there is 29t/hm in the per unit area yield the highest time
2(2008).The all sugar refinery of the whole province are all due to insufficient raw material, of poor benefits, greatly reduce national profits tax and local revenue.In order to increase the yield per unit area, increase economic efficiency, transfer the enthusiasm of peasant planting beet further, agricultural technology spread department actively promotes beet paper tube seedling raising and transplanting technology.
Beet paper tube seedling raising and transplanting technology is the novel culture technique of beet that Japan to develop in eighties of last century the sixties.Through the application and improving of 50 years, be a quite ripe High Yield of Sugarbeet Steady product technique in Japan.This technology has increases beet effective accumulated temperature, prolong growth period, promotes early budding, and resistant to diseases and insects is strong, survival rate of seedlings advantages of higher, Yield-increasing and sugar-increasing Be very effective.Adopt paper-pot cultivation, after seedling replanting to field, because having the seedling age of 4 ~ 5 leaves, not only resistant to diseases and insects is strong, and frost-resistant evil, wind damage resisting.Being not only High-yielding Measures, is also stable yields measure.China, since eighties of last century introduces this technology the eighties, has kept certain area under cultivation always, in recent years paper tube seedling raising and transplanting area 4.5 ten thousand hm every year on average
2left and right.But, because seedling growing process is still at the seedling growing process adopting the Japanese eighties of last century eighties, effectively do not improve culture facility, still in the nursery of employing hut, do not adopt planting early enough, early transplant, extend the advanced technologies such as nursery stage, be still 25 ~ 30 days between nursery stage, cause Raising of Sugarbeet Seedlings in Paper-pots output to be hovered at 45t/hm always
2level.Through our experiment and demonstration in recent years, adopt beet nursery net, technology is completely cured by metal wire, in conjunction with seedling equipment improvement, extend seedling raise period, make seedling age reach the beet paper-pot cultivation new technology such as standard in strong sprout of 40 days, beet root output on average reaches 60.7t/hm
2, than conventional seedbed system technology volume increase beet yield 20.9%, than sugarbeet of direct seeding volume increase 61.9%.
At China publication " a kind of method for raising sugar beet seedlings in paper pots " (application number: 201210082105.7) be openly completely cured educate technology in strong sprout based on beet nursery laying nursery net, metal wire, coordinate the improvement of culture facility, nursery goods, materials and equipments improvement, improve seedbed management, extend seedling raise period by 40 ~ 45 days, solve short between nursery stage in China's beet paper-pot cultivation for a long time, seedling age is little and the easy excessive growth of seedling, resistance is poor, survival rate is low, output is on the low side problem.
Seedling raise period extended to 40 ~ 45 days by original 25 ~ 30 days, prevented seedling excessive growth from being the key of educating strong sprout.Emphasize that seedbed sprays preference temperature moisture in strengthening agent, seedbed cutting lateral root and booth and controls.Method of being wherein completely cured, owing to not having special equipment, since nursery new technology implementation, has adopted small four-wheel tractor to pull metal wire to realize seedbed cutting lateral root always.Because tractor pulling force is uneven, and encounter problems need to stop time, can not stop at once, easily cause seedbed paper volume to cut off, at random, use very inconvenient, root-cutting effect is undesirable.
