Summary of the invention:
The invention solves and in my ground three season of photo-thermal deficiency, the climatic environment of having a surplus in two seasons, make correctly arrange in pairs or groups interplanting and realized and having planted for three seasons of crop, receive the target in three seasons, reach the object of agricultural production increasing both production and income, its technology contents is as follows.
1, autumn potato production technology:
The detoxification potato of selecting dig out spring in by the end of August, at the beginning of 9 months to stay is as Favorita, river taro 56 potato seed strippings and slicings (the not stripping and slicing of the little potato of 25g), keep flat in the cool layer 2-3, the vernalization of every layer of moistening fine earth earthing of use, after one week, in the time that half rice of bud is long, can sow the every mu of 100 kilograms of left and right that make preparations for sowing.
Its type of seeding is that whole well in the plot of preparing kind autumn potato, its land preparation mode can be manually to dig, and also can use rotovator rotary tillage, whole thin leveling.
Sowing specification press 70cm trench digging, then applies fertilizer, and the every mu of organic fertilizer of person that has fertilizer is more than 1000 kilograms, and every mu of the person that there is no fertilizer is by 60 kilograms/666m of superphosphate
2, 60 kilograms/666m of carbonic hydroammonium
2, 30 kilograms/666m of potassium sulfate
2, mix, then the Nitrogen, Phosphorus and Potassium that adds 40 kilograms of N15, P15, K15 applies in ditch in the lump, then after water sufficient water,
After watering, just can sow, every ditch is put two row, and every potato piece is apart from about 24cm, T-shaped pendulum kind, two every trades are apart from 12cm left and right, potato seed bud with upwards downwards can, rear shovel ditch ridging lid kind, high 26cm left and right, ridge.After ridging lid kind, also can cover mulch film, also epiphragma is not carried out outdoor cropping.
Potato is strengthened management after emerging, and mainly prevents and treats budworm, late blight, generally from emerging to gathering in the crops dispenser 3-5 time.
Rape plant after while opening deep bid, the autumn potato start yellow leaf decortication and can receive and dig.
When digging, receipts by the consistent classification of potato block size, fix a price for sale by matter opinion.
2, rape production technology
Grow seedlings: buy while kind and select the Hybrid Oil colza that growing way is strong, degeneration-resistant by force, output is high, grow seedlings mid-September, plants 666m by ground, per minute seedbed
2field seedling raising ratio plan nursery, kind of a 50g for per minute seedbed ground, after broadcasting sowing even 3-5 days and emerging with water sprinkler watering sooner or later, until a week true leaf occur, while bundle under root system, stop, after this doing a good job of it diseases and pests controlling, main anti-cure aphid, cabbage caterpillar.When 30-35 days 4-5 leaves, transplant.
Transplanting rape: late October starts to transplant.Late October, potato entered the vigorous growth later stage, and blade starts flavescence, now, started to beat nest in the ridge, potato ridge one side, while beating nest, note full field ridge side beat nest deflection one to.Beating the nest deflection ridge, ridge is that nest is apart from 30cm, the dark 13cm of nest for people walks conveniently.Every 666m
2land for growing field crops applies 1000 kilograms of fertilizers, and take dung polluted water as main, 60 kilograms of persulfuric acid calcium, 30 kilograms of carbon ammoniums, 20 kilograms of potassium sulfates, mix to apply and accomplish fluently in pothole, then executes people and animals' fertilizer, and 20 choose and convert proper amount of clear water and apply in pothole.
Lifting: note when the tender crisp lifting of rape not injuring breaking seedling, a correct seedling-growing method should shift to an earlier date 1 hour rape seedbed is irrigated to water, then use little sledge sledge pine, the left hand base portion of holding with a firm grip, the right hand withstands root system bottom earth with sledge, and then left hand pulls up gently, lifting generally one by one individual plant pull up, should not several strains one pulling up together, after lifting, one of several strain, forward put into basin or basket or dustpan and wait to transplant.
Transplant: carry out two strain transplantings or individual plant and transplant,, arrange on a line for well with individual plant transplanting, with dig potato and management is all favourable, two strain transplantation clutches are apart from 30cm (generally adopting), individual plant transplanting plant spacing 15cm, after transplanting, water normal root water, after one day, watered resurgent water one time.
Rape is transplanted and is easily survived, and causes and is short of seedling but also have because of insect pest or transplant poor quality, therefore after 4-5 days, looks into seedling and fills a vacancy.
At the beginning of entering 12 months, rape is long 7-8 sheet leaf, quite luxuriant, has covered autumn potato young plant.Now potato is also ripe, now can dig potato, and the potato digging carries out classification sale.
After digging potato, rape is carried out to disposable fertilizer water management, every 666m
2choose clearly with 10-15 that liquid dung is watered and appropriate carbon ammonium topdresses, the fertile and skilful Shi Leitai fertilizer of heavy dressing opening quotation while opening deep bid, until results.
Embodiment
The specific embodiment of the invention: found 0.8 mu of ground as example take 11 groups, court cards village, the Qingjian River town Pan Jing instructing last year.Illustrate.
1, potato sowing
August 26 to seed business, place purchased 80 kilograms of Favorita potato kinds.And in stripping and slicing in second day, soak 1 minute with topsin, be placed in shady and cool place, angle, room, put 3 layers, every layer of moistening fine earth of use separates, in September 5 bud seedling grow to the sowing when long of half rice.
September 4 with rotovator by after ground rotary tillage, and press 70cm line-spacing and ditch, with crossing, 25 kilograms, 50 kilograms, phosphate fertilizer, 50 kilograms of carbon ammoniums, potassium sulfate are mixed to be hooked, is spread in ditch, and separately spreads the composite fertilizer of 30 kilograms of N15, P15, K15, then chooses liquid dung with 15 and be watered and apply in right amount in ditch.
After fertilising, by there is the potato piece of half long young shoot of rice to keep flat in ditch through vernalization length, be put into two row, line-spacing 10cm left and right, spacing in the rows 13cm, wrong nest is put, and is put into T-shaped, when pendulum potato piece, can young shoot upwards, also can be downward, but with downwards for well, darker after can making like this potato emerge, and one goes out root, root just contacts with the following earth of potato piece, favourable Root Absorption nutrient, and young shoot is bent upwards growth, favourable knot potato, with potato piece is imbedded in darker ground, avoid astigmatism to enter and in ground, form rascal potato, reduce commodity.
Set after potato kind, i.e. ridging blinding, builds and is sowing after soil and finishes.
After one week, after emerging, start to prevent and treat late blight with 600 times of liquid of 40% silver medal method profit, and every about 10 days spray medicine once.Potato needed in life to spray medicine and prevented and treated late blight 4-5 time autumn.
2, rape seedling raising and transplanting.In September 12 with 6 lis of vegetable gardens educate Brassica campestris L seedling, transplanted in the time that Brassica campestris L seedling reaches four leaves October 25.In potato ditch, press 30cm room for manoeuvre and beat nest, with crossing 50 kilograms, phosphate fertilizer, 30 kilograms of carbon ammoniums, 15 kilograms of potassium sulfates, mix and apply pothole, and execute 30 kilograms of Nitrogen, Phosphorus and Potassium, people's animal manure 15 is chosen to be watered and is made in right amount base fertilizer, then plays transplantation of seedlings, pressing 15cm room for manoeuvre individual plant transplants, plant into a linely, then water normal root water, within second day, water resurgent water.
