Abstract

The invention discloses a rape field management technology. The invention relates to the technical field of agricultural cultivation, and especially relates to a rape management method. With the technology, rape growth speed and disease resistance can be improved, and rape substance and oil accumulation speed can be improved. The technology is characterized in comprising the following steps: 1, surrounding ditches should be cleaned thoroughly in time in sunny days after rape ends flowering; 2, sclerotinia sclerotiorum is controlled, wherein 50mL of 25% prochloraz missible oil or 60-100g of 50% procymidone wettable powder or 100-150g of 40% dimethachlon wettable powder is mixed with 25-30kg of water, and the mixture is uniformly sprayed in each Mu of field, such that sclerotinia sclerotiorum control is enhanced; 3, aphids are controlled in time, wherein aphid damage is more serious in spring which is usually dry, such that aphid uniform prevention and control should be carried out; and 4, timely harvest should be carried out according to local conditions; a rape mechanized harvest technology is popularized, such that harvesting efficiency and benefit are improved.

Description

Administrative skill between a kind of Rapeseed Field

Technical field

The invention belongs to agricultural planting technique field, especially relate to a kind of rape management method.

Background technology

Rape, is again pakchoi, and bitter dish is the young stem and leaf of crucifer rape, originates in China, and color is dark green, and side, as Chinese cabbage, belongs to the mutation of Cruciferae Chinese cabbage. Widely cultivate in north and south, and the four seasons all have for producing. In rape, containing various nutrients, contained vitamin C is abundant. Rape is that happiness cools, the crop that cold hardiness is stronger, and according to test, 3 ~ 5 DEG C of the minimum temperatures of germination, within 3 days under 20 ~ 25 DEG C of conditions, just can emerge, 14 ~ 18 DEG C of florescence, 12 ~ 15 DEG C of angle fruit puberties, and day and night temperature is large, favourable blooming and angle fruit growth, increases the accumulation of dry and oil content. Rape is long breeding time, and trophosome is large, and result organ number is many, thereby needs water more, and each growing stage to the requirement of moisture is: germination and emergence phase general soil moisture should remain on 65% left and right of field capacity; Elongation florescence is field capacity 75 ~ 85%, and the angle fruit puberty is field capacity 70 ~ 80%.

Although general peasant household all slightly knows about the planting technology of rape. But, in concrete operations management, also there are a lot of problems, affect the speed of growth of rape, the accumulating rate of material and oil content in resistance against diseases and rape.

Summary of the invention

The present invention is exactly for the problems referred to above, and providing a kind of increases growth of rape speed and resistance against diseases, and can increase administrative skill between a kind of Rapeseed Field of the accumulating rate of material and oil content in rape.

To achieve these goals, the present invention adopts following technical scheme.

Administrative skill between a kind of Rapeseed Field, is characterized in that, comprises the following steps.

One, ditch is enclosed in cleaning in time, and the angle fruit phase of reaching maturity usually there will be the precipitation of larger intensity, and the field of hypsography low-lying can form waterlogging disaster, easily causes rotten of rape anoxic and lodging, reduces plant resistance, increases the weight of sclerotiniose and occurs, and affects yield and quality. Therefore after rape is spent eventually, utilize in time fine weather thoroughly to clear up and enclose ditch, ditch is enclosed in maintenance and gutter is unobstructed.

Two, carry out sclerotiniose control, In Middle And Lower Reaches of Changjiang River is about to enter the whole florescence at present, the heavier producing region of historical disease, should according to sclerotiniose scab, a situation arises, every mu of available 25% Prochloraz missible oil 50mL or 50% procymidone can wet-milling 60～100g or 40% dimethachlon can wet-milling 100～150g etc. water 25～30kg be evenly sprayed, the control of strengthening sclerotiniose.

Three, prevent in time eliminating aphis; Spring, weather was often comparatively arid, and aphid damage is often heavier; Easily there is high temperature and drought weather in the end of spring and the beginning of summer, also will perform the work of aphid Unifying control. Can select that Aphox, aphid are quick-fried, lambda-cyhalothrin, alkene pyridine worm peace, Imidacloprid etc. spray, because aphid has the characteristic of migrating, control preferably adopts Unifying control.

Four, suit measures to local conditions to gather in the crops in good time; Widely popularize rape production mechanization results technology, improve efficiency of crop and benefit. To possessing cracking resistance angle, strong, ripe phase of lodging resistance kind early, at all rapeseed plants angle, full field, fruit presents loquat yellow, uses combining of 4LL-2.0D type rape combined harvester when moisture content of kernels 20%.

As a kind of preferred version, weeding is in May, June, July, August, September, and managing and protecting emphasis is weeding, particularly by the end of April to May, June, July weeds vigorous period just, in time weeding. Must artificial weeding apart from nursery stock 40cm place around the cave of planting seedlings, beyond 50cm, scope can be with the timely weeding of herbicide.

Beneficial effect of the present invention.

The present invention passes through the rape field management method of science, encloses ditch by timely cleaning, avoids causing the problem of rotten of rape anoxic and lodging, in addition, by carrying out sclerotiniose control and timely anti-eliminating aphis, the resistance against diseases of rape is strengthened. Therefore the present invention can increase growth of rape speed and resistance against diseases, and can increase the accumulating rate of the interior material of rape and oil content.

Detailed description of the invention

Weeding is in May, June, July, August, September, and managing and protecting emphasis is weeding, particularly by the end of April to May, June, July weeds vigorous period just, in time weeding. Must artificial weeding apart from nursery stock 40cm place around the cave of planting seedlings, beyond 50cm, scope can be with the timely weeding of herbicide.

Most of rape variety that current production is promoted all can adopt swath harvesting; in the time that full field 80% left and right rapeseed plants is loquat Huang; adopt 4SY-2.0 rape cutter-rower or manually cut down, within 5 ~ 7 days, pick up threshing with the self-propelled gathering and threshing mill of 4SJ-1.8 afterwards or manually pick up the rear harvester for both rice and wheat threshing of using. In rice rice oil triple-cropping system producing region, in the time of main inflorescence lower angle fruit seed annesl, gather in time and transfer to Huo Tian limit, threshing ground and stack, as run into precipitation and can cover with film rainproofly, after 5～7 days, spread threshing after airing out, can improve mass of 1000 kernel and oil content, for the rear stubble of rising, alleviate contradiction in season.
