Abstract
The invention discloses a cold resistance screening method for northern latitude 37-degree winter sowed pea resources. The method comprises steps of resource selection, sowing, cold resistance screening, cold resistance grading, and establishment of pea cold resistance core resources. Winter pea sowing experiments are carried out at the northern latitude 37 degrees for the first time, resources stored in a national bank are subjected to cold resistance screening for the first time, the cold resistance of local pea resources collected in China at present is systematically evaluated, cold resistant resources are grated for the first time, a winter pea sowing region is moved north, winter fallow land is fully utilized and the method has significance for utilizing the winter fallow land in the region and increase income of farmers.
Description
Technical field
The present invention relates to a plant species patience screening technique, specifically is the cold-resistant screening technique of a kind of north latitude 37 ° of winter sowing peas resource.
Background technology
Pea is second-biggest-in-the-world edible legume crop, and cultivated area is 100,000,000 mu throughout the year, in the crop rotation rotation of crops, livestock breeding and sustainable agriculture development, plays an important role.In recent years, along with the adjustment of eating pea, starch processing, Developing of Animal Industry and pattern of farming raw, pea product purchasing price rises, and the output value obviously improves, and the enthusiasm that the wide farmers plantation is produced significantly increases.Eat in the pea production characteristics such as fertilizer uses less, residue of pesticide are low winter raw and make it become high-end green vegetables, ensuring food safety and enriching aspect such as people's vegetable basket project and bringing into play important effect.
Qingdao is positioned at the intermediate region in the pea winter sowing district and the district that sows in spring, and winter minimum temperature has a large amount of open countrys idle about-10 ℃ winter.Simultaneously, the orchard worker is because soil acidification is serious, and inter-row weed management in orchard is time-consuming, is seeking a kind of earthing plant, between early June mid-October to next year, is sowed at the orchard in the ranks, reaches the purpose of improving the soil and suppressing weed growth.And the research and development of corresponding cultivation techniques such as the screening of cold-resistant pea kind and proper seeding for making full use of ground in winter slack, improve the orchard soil ecotope, and increasing farmers' income has great significance.
In recent years, the researcher of states such as the U.S., France and Syria takes to the screening study of the cold-resistant kind of pea.They think: global warming causes some areas winter temperature to rise, and the area of suitable pea winter sowing can not attempted the cold-resistant kind of seed selection part now originally.The pea resource of American scholar Hu Jinguo filters out anti--18 ℃ of low temperature; The cold-resistant kind of pea of France scholar G é rard Duc screening can be under-15 ℃ of low temperature safe overwintering; The cold-resistant pea resource of Syria scholar Malof all can be-13 ℃ of survivals.Above-mentioned scholar's research also only is the starting stage, does not also see formal report at present, is merely academic exchange information.Studying residing area also is in 37 ℃ of zones of north latitude, and therefore, this project early-stage Study is carried out with correlative study in the world synchronously, and learning value and using value have good prospects.This research is subsidized (CARS-09) by modern agriculture industrial technology system special fund.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind ofly carries out the cold-resistant resource method for screening of pea in 37 ℃ of zones of north latitude, has realized pea winter sowing zone is moved northward, and makes full use of ground in winter slack, the purpose of increasing farmers' income conscientiously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
The cold-resistant screening technique of a kind of north latitude 37 ° of winter sowing peas resource may further comprise the steps:
(1) resource selection
With the pea local supplies sampling of collect preserving in the national germplasm storehouse, 25 of every part of resources;
(2) sowing
Mid or late October is seeded in 37 ℃ of regional test bases of north latitude then, the completely random design, and the trench digging bunch planting, line-spacing 40cm, the cave is apart from 3-4cm, and trench digging degree of depth 4-5cm broadcasts big flood flood irrigation in preceding 7 days and makes moisture in the soil;
(3) cold-resistant screening
After early November, pea was emerged then, every part of resource of investigation statistics number of emerging;
When temperature drops to below 0 ℃, when pea patch top stops growing, every part of resource seedling of investigation statistics number, and gather single part of resource digital photograph;
When temperature reaches minimum, every part of resource seedling of investigation statistics number, and gather single part of resource digital photograph;
Before March next year, acrial part turned green, every part of resource seedling of investigation statistics number, and gather single part of resource digital photograph;
In March next year-June, the pea growing period is put down in writing every part of resource flowering stage, pattern, leaf, habit of growth;
After June next year, pea was gathered in the crops, species test, record yield traits;
(4) cold-resistant classification
1 grade: HR, acrial part is green entirely in the time of infertility, output is arranged, anti--13 ℃ of low temperature;
5 grades: MR, acrial part are all withered, but the root survival grows blade again after turning green, output is arranged, anti--13 ℃ of low temperature;
9 grades: HS, plant is all withered, no output;
(5) the cold-resistant core resource of pea makes up.
The invention has the beneficial effects as follows:
The present invention carries out the test of pea winter sowing 37 ° of north latitude first; And first resource is preserved in national storehouse and carry out cold-resistant screening; China is collected at present the pea local supplies cold resistance of preservation and carried out system evaluation, first cold-resistant resource is carried out classification, reached pea winter sowing zone is moved northward;, utilization and the increasing peasant income for ground in winter slack, this area have significant role with making full use of winter slack.
