Rape yield per mu
The yield per mu of rape is generally around 300 kg. If the variety is well selected, the environment is suitable and the management method is proper, it can reach more than 350 kg, and the water and fertilizer can keep up, which can reach 400-500 kg.
Prospect of rape planting
The cost of rape may be the purchase of rape seeds, fertilizer, land lease and labor costs. , a year 1000 yuan. The market price of rape is three to five yuan a catty, the average yield per mu is about 800 kg to 1000 kg a year, and the income is about 2400 to 3000 yuan.
Rape has strong adaptability to the environment and relatively simple management. Moreover, rape occupies a very important position in many industries, which can provide a lot of oil and feed and promote the development of tourism, so it has a bright future.
How to plant rape to achieve high yield?
1, seed selection and seed soaking
You can use the seeds in the rape pod of last year, choose the seeds with full seeds and no pests, put the selected seeds in salt water for disinfection, soak them in salt water with the concentration of 10% for about 5 minutes, stir them, and then wash the seeds, so as to remove the sclerotium impurities mixed in the seeds.
2. Land selection and preparation
Choose a location with convenient irrigation and drainage and loose and fertile soil. You can plough the land, break the clods, and plough through at least 20 cm. If the soil fertility is insufficient, farmyard manure can be properly added and ploughed together with the soil. Loose and breathable soil is beneficial to seed germination and respiration.
Step 3: sow seeds
After ploughing the land, wait 2-3 days before sowing. Dig several small ditches in the ground and sprinkle rapeseed on the slopes of the ditches. After sowing, cover the soil layer with a thickness of 1.5 cm. Sprinkle water properly on the slope, sprinkle water in the ditch, and sprinkle water gently to avoid washing away the seeds directly.
4. Fertilization management
Rape planting should be scientifically fertilized, and generally sufficient base fertilizer, early seedling fertilizer, heavy wax fertilizer and moss-stabilizing fertilizer should be applied. At the same time, we must pay attention to the use of boron fertilizer in rape planting to promote flower bud differentiation and seed setting rate.
Step 5 weed the fields
Compared with wheat and rice, the weeding work of rape is a little easier, but the planting of rape should also be sealed before germination. Once the closure is well managed, the pressure of chemical weeding in the later stage is very small, and the stubble removal of old grass should also be done before planting.
