Abstract

The invention discloses a planting method for interplanting pea before sowing of sunflower. The planting method mainly includes: when fertilizing and mulching a land block where sunflower is prepared to be planted in early spring, planting pea on line space films reserved for sunflower at planting time about 20th March; watering the pea for the first time in early May, and combining watering with fertilizing; planting sunflower in reserved lines at the time from the end of May to the beginning of June; harvesting pea at the beginning of July, wherein yield of pea per mu is about 200kg generally, and yield of sunflower is not reduced basically and can reach about 250kg. High-efficiency three-dimensional planting technology is developed according to the circumstance that a Hetao irrigation area is sufficient for one crop and insufficient for two crops, and has the advantages that light, heat and soil resources are utilized fully, one-season two-harvest is realized, ground surface exposure is reduced, and sand storm is prevented. The planting method has double effects of increasing yield and income and protecting ecological environment of farmland and is high in practicability and wide in application prospect.

Description

A kind of sunflower broadcasts the implantation methods of protheca replay pea

Technical field

The present invention relates to the implantation methods of a kind of sunflower replay pea, refer in particular to the implantation methods that a kind of sunflower broadcasts protheca replay pea.

Background technology

Sunflower is the essentialspecies plant of China's Hetao Irrigation District, and sowing area accounts for 1/3rd of total area under cultivation.Sowing at the beginning of major part sunflower at the end of May to 6 month, before broadcasting and seedling stage sunflower planting field have the leisure free time of nearly 3 months, for Planting Fast-growing cold-resistant crop creates space-time condition.Soil does not add utilization phase at this moment, then serious waste soil and sunlight-heat reaources, and northern area strong wind in spring occurrence frequency is higher, and large area earth's surface is exposed as easy as rolling off a logly brings out sand and dust harm, causes potential threat to environment.Therefore, this area research sunflower broadcast front arable land Appropriate application to peasant's increasing both production and income, to spring Wind Erosion in Farmland desertify control particularly urgent.Promoted by integrated technology and constantly perfect, it is necessary that sunflower broadcasts the resist cold planting technology of fast-growing pea of protheca replay short-term.

Summary of the invention

The technical problem to be solved in the present invention is to provide the implantation methods that a kind of sunflower broadcasts protheca replay pea, the method is in the field preparing plantation sunflower, apply fertilizer early spring overlay film time plantation pea, on film, reserved sunflower planting is capable simultaneously, pea implantation time is on March about 20, the first tenday period of a month in May, pea watered the first water, 15 ~ 20 kilograms, urea is imposed in conjunction with watering every mu, on reserved row plantation sunflower at the beginning of by the end of May to 6 month, pea results at the beginning of 7 months, now sunflower plant height only 15 cm, grow substantially unaffected.

The technical problem to be solved in the present invention is realized by following scheme: a kind of sunflower broadcasts the implantation methods of protheca replay pea, it is characterized in that: 20 ~ March 30 March is with wide-film sowing machine sowing kind pea, sowing, fertilising, overlay film is disposable to be completed, adopt the mulch film of 1.6 ~ 1.7 meters wide, in mulch film in 1.8 ~ 2.0 meters, be with seed manure diammonium phosphate 10 ~ 20 kilograms for every mu, plantation pea 3 row in the middle of on film, line-spacing 30 ~ 35 centimetres, cave is apart from 20 ~ 30 centimetres, every mu of 4000 ~ 4500 caves, every cave seeding down 3 ~ 6, not thinning after emerging, the first tenday period of a month in May, pea watered the first water, 15 ~ 20 kilograms, urea is imposed in conjunction with watering every mu, sunflower was sowed 30 ~ June 10 May, dibbling is in film limit 5 ~ 10 centimeters, apart from pea 30 ~ 35 centimetres, sunflower spacing in the rows 30 ~ 35 centimetres, mu stays seedling 2000 ~ 2500 strain, two intermembranous sunflower line-spacings 50 ~ 60 centimetres.Estimate sunflower output about 250 kilograms, pea output about 200 kilograms.The present invention be directed to have a surplus in Hetao Irrigation District one season, two seasons deficiency research and development a High-efficiency Spatial Planting Technique.Pea is high-quality legume, and can make Fodder and food, the prospect of marketing is larger.

Advantage of the present invention is: the technical advantage of pea intercropping sunflower is, one is the priority in sowing time making full use of two works, and stagger Growing season, extend campaign, pea was gathered in the crops before July 10, with only about 30 days sunflower intercropping symbiosis phase, substantially there is not symbiosis contradiction.Sunflower is equivalent to single, improves the availability of light, heat and soil resource, achieve a season two ripe, increase production and improve productivity.Two is that input cost is low, and output is high.The input cost of pea is lower, and output is high.Pea is not only less demanding to fertility but also have nitrogen fixation, can culture fertility, improves soil property, is beneficial to sunflower late growing stage, alleviates disease, realize cost-saving synergistic.Three to be the reduction of spring earth's surface exposed, effectively can prevent and treat the generation of sandstorm.Four is peas is high-quality legumes, and the prospect of marketing is comparatively large, and eating raw, food processing, bud dish reserve seed for planting, have needs in livestock and poultry cultivation high protein feed etc., can develop into the new industry bringing along farmers to increase income completely.

Accompanying drawing explanation

Fig. 1 is the implantation methods schematic diagram that sunflower broadcasts protheca replay pea.

Embodiment

With wide-film sowing machine sowing kind pea before and after March 20, sowing, fertilising, overlay film is disposable completes.Adopt 1.6 ~ 1.7 meter films, in mulch film in 1.85 meters, every mu of band seed manure diammonium phosphate 15 kilograms, plantation pea 3 row in the middle of on film, line-spacing 33 centimetres, cave apart from 26.6 centimetres, every mu of 4177 caves, every cave seeding down 3 ~ 6, not thinning after emerging.The first tenday period of a month in May, pea watered the first water, imposed 15 ~ 20 kilograms, urea in conjunction with watering every mu, and sunflower was sowed 30 ~ June 10 May, dibbling in film limit 5 centimeters, apart from pea 32 centimetres, sunflower spacing in the rows 33 centimetres, mu stays seedling 2245 strain, two intermembranous sunflower line-spacings 55 centimetres.Estimate sunflower output about 250 kilograms, pea output about 200 kilograms.

Claims

1. a sunflower broadcasts the implantation methods of protheca replay pea, it is characterized in that: 20 ~ March 30 March is with wide-film sowing machine sowing kind pea, sowing, fertilising, overlay film is disposable to be completed, adopt the mulch film of 1.6 ~ 1.7 meters wide, in mulch film in 1.8 ~ 2.0 meters, be with seed manure diammonium phosphate 10 ~ 20 kilograms for every mu, plantation pea 3 row in the middle of on film, line-spacing 30 ~ 35 centimetres, cave is apart from 20 ~ 30 centimetres, every mu of 4000 ~ 4500 caves, every cave seeding down 3 ~ 6, not thinning after emerging, the first tenday period of a month in May, pea watered the first water, 15 ~ 20 kilograms, urea is imposed in conjunction with watering every mu, sunflower was sowed 30 ~ June 10 May, dibbling is in film limit 5 ~ 10 centimeters, apart from pea 30 ~ 35 centimetres, sunflower spacing in the rows 30 ~ 35 centimetres, mu stays seedling 2000 ~ 2500 strain, two intermembranous sunflower line-spacings 50 ~ 60 centimetres.
