Abstract

The invention discloses a relay intercropping method of flue-cured tobacco, wheat and sweet potatoes. The method is suitable for the Huang-Huai tobacco-growing area of our country. The method comprises the steps that field fertilization is carried out in October of a first year, deep ploughing and thorough harrowing are carried out, ridging is carried out according to the requirements that the ridge distance is 100-120cm, the ridge width is 30-40cm, and the ridge height is 15-20cm, 5-8 rows of the wheat are planted between ridges, and the row distance of the wheat is 15-20cm; the flue-cured tobacco is planted on the ridges in May of a second year, and the plant distance of the flue-cured tobacco is 50cm; the wheat is harvested in June of the second year, wheat straw is returned to the field in the same month, deep ploughing and thorough harrowing are carried out, and the sweet potatoes are planted with a fixed distance at the original wheat planting positions; the flue-cured tobacco and the sweet potatoes are simultaneously harvested in September of the second year, and sweet potatoes straw is returned to the field.

Description

A kind of interplanting method of flue-cured tobacco, wheat and sweet potato

Technical field

A kind of interplanting method that the present invention relates to flue-cured tobacco, wheat and sweet potato, belongs to agricultural planting field.

Background technology

The Yellow River and Huai He River cigarette district major part is taked flue-cured tobacco nonoculture, and the cropping index of crop is lower; Annual 5-6 month is the peak period of flue-cured tobacco studies of migration of aphids, expansion, the virus disease propagation of working the mischief of migrating of aphid.Nonoculture flue-cured tobacco, as long as certain part crop infects aphid, can have influence on full wafer vega very soon; If there is the existence of a large amount of nitrogenous fertilizer on cigarette ground in tobacco planting process, nitrogen supply too much can cause the remaining green when it is due to become yellow and ripe late-maturing formation of cigarette strain " black quick-fried cigarette ", affects the quality of tobacco leaf, has reduced the benefit of tobacco grower's plantation.

Summary of the invention

The object of the invention is to solve the aforementioned problems in the prior, a kind of interplanting method of flue-cured tobacco, wheat and sweet potato is provided, both promoted the yield and quality of flue-cured tobacco, improved again the cropping index of vega, greatly increased tobacco grower's income.

In order to achieve the above object, the technological means adopting is in the present invention:

1). First Year October, deep ploughing target was saturating at field fertilization, by row spacing 100-120cm, row spacing 30-40cm, the high 15-20cm requirement in ridge ridging is sowed the capable wheat of 5-8, little line-spacing 15-20cm between ridge;

2). Second Year is planted flue-cured tobacco May on ridge, and flue-cured tobacco spacing in the rows is 50cm;

3). Second Year is gathered in the crops wheat June, and this month, by wheat straw farmland returning, deep ploughing target was saturating, in former wheat planting position, spacing plantation sweet potato;

4). Second Year is gathered in the crops flue-cured tobacco and sweet potato, sweet potato straw-returning September simultaneously.

Said method is applicable to China's the Yellow River and Huai He River cigarette district.

Compared with prior art, the present invention has following characteristics and effect: 1) annual 5-6 month is the peak period of flue-cured tobacco studies of migration of aphids, at this moment high by the flue-cured tobacco height of the aspect ratio plantation in May of wheat between the ridge of the present invention's plantation, effectively stopped migrating and viral propagation of aphid; 2) nitrogenous fertilizer of sweet potato later stage needs is more, has just utilized the nitrogenous fertilizer in vega, prevents because nitrogen supply too much causes the remaining green when it is due to become yellow and ripe late-maturing formation of cigarette strain " black quick-fried cigarette "; 3) provide the cropping index in field; 4) wheat, sweet potato both can be sold the income that both can increase peasant, and wheat, sweet potato stalk can be gone back field again, improve nutrient and the content of organic matter of soil; 5) tobacco leaf is the economic crops of results blade, and when running into the hail disaster time, tobacco leaf occurs that poor harvest even has no harvest, and tobacco grower also can readjust income distribution by wheat and sweet potato, greatly reduces the natural risk of single cropping flue-cured tobacco.

Embodiment

Below in conjunction with embodiment, the invention will be further described:

Flue-cured tobacco is selected local main breed, and as cloud and mist 85, wheat is selected high-quality strong gluten wheat breed, and as ligusticumic wheat 8901, sweet potato selects growth potential strong, colory kind.

October, deep ploughing target was saturating at field fertilization then, by row spacing 100-120cm, and row spacing 30-40cm, the high 15-20cm in ridge requires ridging, sows the capable wheat of 5-8, little line-spacing 15-20cm between ridge;

On ridge, plant flue-cured tobacco May next year, flue-cured tobacco spacing in the rows is 50cm;

Gather in the crops wheat June, this month, by wheat straw farmland returning, deep ploughing target was saturating, in former wheat planting position, and spacing plantation sweet potato;

Gather in the crops flue-cured tobacco and sweet potato September, sweet potato straw-returning simultaneously.

Claims

1. an interplanting method for flue-cured tobacco, wheat and sweet potato, is characterized in that, comprises the following steps:

1) First Year October, deep ploughing target was saturating at field fertilization, by row spacing 100-120cm, and row spacing 30-40cm, the high 15-20cm requirement in ridge ridging is sowed the capable wheat of 5-8, little line-spacing 15-20cm between ridge;

2) Second Year is planted flue-cured tobacco May on ridge, and flue-cured tobacco spacing in the rows is 50cm;

3) Second Year is gathered in the crops wheat June, and this month, by wheat straw farmland returning, deep ploughing target was saturating, in former wheat planting position, and spacing plantation sweet potato;

4) Second Year is gathered in the crops flue-cured tobacco and sweet potato, sweet potato straw-returning September simultaneously.

2. interplanting method as claimed in claim 1, is characterized in that, described method is applicable to China's the Yellow River and Huai He River cigarette district.
