Abstract
The present invention relates to a kind of rice district sweet potato implantation methods, paddy rice toothing 40 centimetres, sweet potato seeding quantity 2.5 thousand grams/acre, 3 kgs/acre, ammonium sulfate, superphosphate 20,000 grams/acre, at least 5 thousand grams/acre, potassium chloride, 0.5 kg/acre, zinc sulphate, ammonium molybdate 0.02 kg/acre; Semidwarf rice kind toothing is shorter, after rice harves, sweet potato is evenly sprinkled into Tanaka, spreads fertilizer over the fields phosphorus potash fertilizer simultaneously and promotes sweet potato growth.Advantageous Effects of the present invention embodies in the following areas: solve sweet potato and to crawl the balance of growth to spatial development, be conducive to the growth of sweet potato; Regulate sweet potato to turn over rear C, N balance, what balance growth period duration of rice needs fertilizer; Increase paddy rice stubble height, can increase the green forage yield of sweet potato, soil of having fostered and apply fertilizer, improves rice yield, and then increases the economic benefit of sweet potato and paddy rice.
Description
Technical field
The present invention relates to a kind of rice district sweet potato implantation methods, belong to agriculture field.
Background technology
Sweet potato be a kind of annual or more year raw pulse family draft green manure crop.Using sweet potato as rice district green manure in winter, there is very strong nitrogen fixing capacity, while providing free of contamination organic nitrogen for lower stubble paddy rice, also there is the function of fertilizing soil, balance and adjustment rice absorbing nitrogen, phosphorus, potassium and medium trace element and increase agricultural product protein content.Sweet potato stem is climing reaches 2-3 rice, growth characteristic of crawling, and stays differing heights rice stubble after plantation sweet potato when rice harves according to rice varieties, is beneficial to sweet potato growth.Meanwhile, sweet potato is the crop that nitrogenous higher C/N is lower, and the nitrogenous lower C/N of rice straw is higher, and plantation sweet potato paddy rice stays high stubble, and solve sweet potato and turn over rear C, N balance, " carbon nitrogen helps mutually ", is conducive to paddy growth.
Summary of the invention
The present invention relates to a kind of rice district sweet potato implantation methods, paddy rice toothing 40 centimetres, sweet potato seeding quantity 2.5 thousand grams/acre, 3 kgs/acre, ammonium sulfate, superphosphate 20,000 grams/acre, at least 5 thousand grams/acre, potassium chloride, 0.5 kg/acre, zinc sulphate, ammonium molybdate 0.02 kg/acre; Semidwarf rice kind toothing is shorter, after rice harves, sweet potato is evenly sprinkled into Tanaka, spreads fertilizer over the fields phosphorus potash fertilizer simultaneously and promotes sweet potato growth.
Advantageous Effects of the present invention embodies in the following areas:
1, solve sweet potato and crawl growth to the balance of spatial development, be conducive to the growth of sweet potato;
2, regulate sweet potato to turn over rear C, N balance, what balance growth period duration of rice needs fertilizer;
3, adding the trace elements such as Zn, Mo, providing sweet potato to grow the micro-demand easily lacked soil, lower stubble paddy rice can be provided again the needs of trace element, increase sweet potato and rice yield and economic benefit;
4, increase paddy rice stubble height, can increase the green forage yield of sweet potato, soil of having fostered and apply fertilizer, improves rice yield, and then increases the economic benefit of sweet potato and paddy rice.
Embodiment
Hereinafter, will describe the present invention more fully now, show various embodiment.But the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, provide these embodiments to make the disclosure will be thoroughly with completely, and scope of the present invention is conveyed to those skilled in the art fully.
Embodiment 1
A kind of sweet potato implantation methods is made up of following: paddy rice toothing 40 centimetres, sweet potato seeding quantity 2.5 thousand grams/acre, 3 kgs/acre, ammonium sulfate, superphosphate 20,000 grams/acre, 5,000 grams/acre, potassium chloride, 0.5 kg/acre, zinc sulphate, ammonium molybdate 0.02 kg/acre.(formula is lower limit amount)
Semidwarf rice kind (paddy rice height is below 1.1 meters) toothing is shorter.After rice harves, sweet potato is evenly sprinkled into Tanaka, spreads fertilizer over the fields phosphorus potash fertilizer simultaneously and promote sweet potato growth.Its method can increase sweet potato green forage yield 30%, can turn over and make paddy rice fertilizer, can increase rice yield 8% when sweet potato blooms.
Embodiment 2
A kind of sweet potato implantation methods is made up of following: paddy rice toothing 60 centimetres, sweet potato seeding quantity 3.5 thousand grams/acre, 3 kgs/acre, ammonium sulfate, superphosphate 30,000 grams/acre, 10,000 grams/acre, potassium chloride, 0.5 kg/acre, zinc sulphate, ammonium molybdate 0.02 kg/acre.(formula is upper limit amount)
High stalk rice varieties (paddy rice height is more than 1.3 meters) toothing is higher.After rice harves, sweet potato is evenly sprinkled into Tanaka, paddy rice toothing is higher, prevents putting seed phenomenon, is after planting stirring stalk gently with bamboo pole, the seed rested on stalk is dialled the face of landing.Spread fertilizer over the fields phosphorus potash fertilizer simultaneously and promote sweet potato growth.Its method can increase sweet potato green forage yield 50%.Can turn over when sweet potato blooms and make paddy rice fertilizer, rice yield more than 12% can be increased.Sweet potato part harvesting also can dry when being greater than 2,500 thousand grams/acre and make animal and fowl fodder by sweet potato green forage yield.
Embodiment 3
A kind of sweet potato implantation methods is made up of following: paddy rice toothing 50 centimetres, sweet potato seeding quantity 3.0 thousand grams/acre, 3 kgs/acre, ammonium sulfate, superphosphate 25,000 grams/acre, 7.5 thousand grams/acre, potassium chloride, 0.5 kg/acre, zinc sulphate, ammonium molybdate 0.02 kg/acre.(formula is intermediate quantity)
Middle stalk rice varieties (paddy rice height is at 1.1-1.3 rice) toothing is moderate.After rice harves, sweet potato is evenly sprinkled in paddy field, spreads fertilizer over the fields phosphorus potash fertilizer simultaneously and promote sweet potato growth.Its method can increase sweet potato green forage yield 40%.Can turn over when sweet potato blooms and make paddy rice fertilizer, rice yield 10% can be increased.Also sweet potato results can be dried as animal and fowl fodder.
From three examples implemented, embodiment 2 units increased in production is maximum, and commodity, economic benefit are the highest.
Below the Comparative result table of common species method for planting and the inventive method:
As seen from the table, plantation sweet potato paddy rice stays high stubble compared with common species method for planting, and the climing length of sweet potato stem increases by 1.2 meters, and sweet potato stem stalk slightly increases by 0.1 centimetre, and natural height increases by 20 centimetres, and green forage yield increases by 1,000 thousand grams/acre.Sweet potato turns over rear lower stubble increasing production of rice more than 60,000 grams/acre, and soil organic matter relative quantity increases by 4.6%.Apply paddy rice when planting sweet potato as can be seen here and stay high stubble cutting and planting method, sweet potato sowing quantity reduces, and paddy rice utilization rate of fertilizer increases, and the increase of paddy rice per mu yield is extremely remarkable, has promotional value very much.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable change and change.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
