Embodiment Construction

[0014] A rapeseed field management technique is characterized by comprising the following steps.

[0015] 1. Clean up the surrounding ditches in time. During the mature stage of siliques, there will often be heavy rainfall, and low-lying fields will form waterlogging disasters, which will easily lead to anoxic root rot and lodging of rapeseed, reduce plant resistance, and aggravate sclerotia disease, affecting yield and quality. Therefore, after the final flowering of rapeseed, it is necessary to use the fine weather to clean up the surrounding ditches in time to keep the surrounding ditches and drainage channels unimpeded.

[0016] 2. Do a good job in the prevention and control of sclerotinia. The middle and lower reaches of the Yangtze River are about to enter the final flowering period. In the production areas with heavy historical diseases, 25% prochloraz EC 50mL or 50% Spray 60-100g of procymidone wettable powder or 100-150g of 40% sclerotia net wettable powder on 25-30k...

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

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a rapeseed management method. Background technique [0002] Rapeseed, also known as oily cabbage and bitter cabbage, is the tender stem and leaf of Brassicaceae rape. It is native to my country. It is dark green in color and looks like cabbage. It is a variety of Brassicaceae cabbage. It is widely cultivated in the north and south, and is available in all seasons. Rapeseed contains a variety of nutrients, including rich vitamin C. Rapeseed is a cold-loving crop with strong cold resistance. According to experiments, the lowest temperature for seed germination is 3-5°C, and seedlings can emerge in 3 days at 20-25°C. The flowering period is 14-18°C, and the siliques develop. 12~15℃, and the temperature difference between day and night is large, which is conducive to flowering and silique development, and increases the accumulation of dry matter and oil. ...
