The Latest Rapeseed Planting Time and Method Explained in Detail
Rapeseed is mainly used for pressing oil; the common sesame oil in our daily lives is pressed from rapeseed seeds. But when rapeseed is still a young seedling, roughly five to ten centimeters tall, it can also be served as a vegetable on people's dining tables. Although we often come into contact with products made from rapeseed, how exactly is it grown? When should it be planted? Then let's take a look together with the editor!
Planting Time
We may all only know when rapeseed flowers bloom, because the blooming of rapeseed flowers can be considered a beautiful scenic sight, but we do not necessarily know when rapeseed is sown. Different regions have different temperatures and environments, so the planting time will also vary to some extent. Generally speaking, rapeseed is sown in autumn and winter and blooms in spring. But in some regions it can also be planted in spring.
Planting Methods
Site selection and land preparation: Rapeseed has strong adaptability, so its requirements for soil are not that strict, but for relatively clayey land, when preparing the land, be sure to first turn the soil over and let it dry in the sun for a few days. Before sowing, water the land once, and after about two days spread compound fertilizer and turn the soil over again.
Planting methods: There are two ways to plant rapeseed. The first is direct sowing, sowing rapeseed seeds in rows at a certain spacing, and after seedlings grow, thinning out the denser areas, which can be taken for cooking. The second way is to first cultivate rapeseed seedlings, and then transplant them one by one at a certain spacing.
Field management: When rapeseed grows to 15-20 cm, fertilize and weed the field once. The fertilizer applied this time is urea, for the purpose of growing seedlings. When rapeseed grows to about forty centimeters, apply fertilizer a second time, and this time the fertilizer is farmyard manure. The last fertilization is before flowering, spraying boron fertilizer, which helps make the later fruits more abundant.
⟦NL>Preventive Measures
Common rapeseed diseases include sclerotinia and seedling damping-off. For sclerotinia, it means you need to be more diligent, promptly clean up and drain waterlogging in the field, and reduce moisture. For seedling damping-off, special chemicals need to be used for spraying and killing. Ordinary growers all know that if rapeseed blooms in winter, it will cause a significant decrease in yield the following year, so to prevent this problem, farmers spray paclobutrazol in advance.
Harvesting
Harvesting must be timely. If too early, many seeds are still immature; if too late, they will all fall off. So the usual harvest time is when the siliques of the whole rapeseed plant are yellow-green. This is the most suitable period for harvest. After harvesting, it should be dried in the sun, and then after later drying, threshing, and a more careful screening, it is ready.
Planting rapeseed is actually very simple. If some people are a bit lazy and are not doing it to increase yield, they only need to plant the rapeseed, then apply fertilizer once, kill insects once, and afterward they can wait to harvest the seeds. Alright, this is a simple rapeseed planting method that Qinong Web has introduced to everyone today. Have you all remembered it? If you have a better method, you can also recommend it to the editor!
