What is the yield of rapeseed per mu? How do you plant it? How to store it without going bad? Rapeseed Price Forecast in 2018

Rapeseed, also known as Brassica, is the seed of rape, a cruciferous crop. Rapeseed has longer pods, more pods and full seeds. So what is the yield of rapeseed per mu? How do you plant it? How to store it without going bad? What is the price of rapeseed in 2018? I learned from Mr. Liu, a rape grower in Hunan, that if it is managed according to the management mode of high-yield fields, every 667 square meters of rape can produce 400-450 jin, and we must grasp the application of sufficient base fertilizer, boron fertilizer, anti-freezing measures at seedling stage, and follow-up pest and pest management. and field management.

How to grow rapeseed?

1. Heavy application of winter fertilizer: winter fertilizer has the function of keeping warm, preventing frost and promoting spring. Generally speaking, winter fertilizer is applied to rape field in the middle and last ten days of December, combined with soil cultivation. Winter fertilizer should be based on late-acting barnyard manure and cake fertilizer, combined with a certain amount of plant ash and calcium superphosphate.

2. Protection against cold and freezing. Covering the rape border with rice straw, sprinkling plant ash or rotten fine organic fertilizer can not only increase the soil temperature, enhance the cold resistance and frost resistance of rape, ensure the rape to survive the winter safely, but also improve the soil structure. For rape fields with high groundwater level, attention should be paid to clearing ditches and discharging water, so as to avoid waterlogging into ice and aggravate freezing damage.

3. Chemical control squatting seedlings. If the rape transplanted early is too prosperous, it can be sprayed in the middle and late December to make the plant stem stout, leaves thick, leaf color fresh and tender, plant luxuriant and natural taste strong. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

4. Prevent diseases and insects. Rape diseases and insect pests are mainly Sclerotinia sclerotiorum, downy mildew, white rust and aphids. At present, aphids are the most harmful, and at the same time, aphids also spread viral diseases, so in order to cure early, cure well, and play the role of pest control and disease prevention, we can use imidacloprid 3000 Mel 4000 times liquid spray + new high fat membrane to control aphids. The disease of rape after the beginning of spring can be used to deepen the "three ditches", lower the groundwater level, remove the lower old leaves, at the same time, at the early flowering stage, the rate of leaf disease is up to 10%, and the stem disease rate is up to 1%. Spray control with 50% carbendazim plus new high-fat film.

How can rapeseed be stored without going bad?

Rapeseed has a high oil content, about 35% to 40%, which is generally considered to be not resistant to storage. And strong hygroscopicity, high temperature in mature period, more Rain Water, poor storage after harvest is easy to absorb moisture and sprout, lose edible value, and the stability of newly harvested rapeseed is poor, so management should be strengthened and scientific storage should be strengthened. Rapeseed storage mainly pays attention to the following aspects:

1. Dry and remove impurities and control moisture. Rapeseed should be dried in time after harvest, and the moisture content of rapeseed stored in storage should be reduced.
