When is the best time to harvest rape?

The harvest time of rapeseed is different between the east and west of the motherland, the south and the north. Generally speaking, the northern, eastern and western regions are about the same as the wheat harvest time, about five to ten days early. The west of Shandong is before and after Lesser Fullness of Grain, the middle is in front of Grain in Beard, and Jiaodong is behind Grain in Beard. The harvest time of the south is similar to that of the first cropping rice.

To judge when rape is suitable for harvest, you can start from the following three aspects:

Rape from flowering to the end of flowering, about 2 months, after flowering, then bear fruit, form rapeseed, wait for rapeseed to mature for about a month, farmers can harvest, to seize the opportunity, not too early too late. If harvested too early, the upper pod is not yet mature, it will reduce the yield and grain quality; on the contrary, if the harvest is too late, the early pod is easy to crack and drop seeds, which also affects the yield and quality of rapeseed.

1. Look at the appearance: the pod loquat is yellow, and the harvest is just the same. In the whole field, the pods of 2 picks are yellowish green, the pods in the middle of the main axis are loquat color, and the whole plant is still green when the pods are green, which is the suitable harvest time for rape.

2. Timing: generally, about 25-30 days after the final flowering of rape, it is the suitable harvest time for rape.

3. Look at the seed color: take 10 pods in the middle of the main axis, upper and middle branches, peel off and observe the seed color. If the brown grain and semi-brown and semi-red grain are half each, it is the suitable harvest time.

Rape harvest method

Rapeseed is suitable for a short harvest period, so it is necessary to grasp the opportunity to harvest with dew in the sunny morning to prevent pods from falling. The harvest process strives to achieve the "four light" (light cutting, light handling, light binding, light transportation), and strive to minimize the loss in each link. Rape harvest, while harvesting, while bundling, while pulling, while stacking, should not be stacked in the field, drying, in order to prevent cracking and falling grains. Generally stacked 4-6 days after harvest, catch the sunny morning in time to scatter, spread, thresh, dry and clean.

Rape harvesters usually cost 2200 yuan each.
