As if a golden carpet had been laid for the earth, and its beauty was envious. Moreover, the value of oily vegetables not only is extremely high, but their seeds are valuable raw materials for extracting oil for consumption, and economic values cannot be ignored. Next, we'll have an in-depth understanding of the techniques of growing oil and vegetable flowers, from preparation to harvest。

The selection and the ground
Landing and landscape-building are the first steps in the cultivation of vegetable oil. Vegetables tend to be deep, fertilized and drained. These conditions therefore need to be fully taken into account in the selection of the site. The selection of plots is followed by deep-drink cultivation, usually at depths between 20 and 30 centimetres, which ensures that the soil is sufficiently lax to allow for air intake, thereby contributing to the healthy development of the vegetable root system. In addition, adequate basic fertilization is key, with the option of agricultural household and compound fertilization. Usually, between 1,500 and 2,000 kg of farm fat and 30 to 40 kg of compound fat per acre are applied, so that the fertilizer is evenly distributed and then tilled。
Varieties selection
The selection of suitable oily varieties is essential. The selection of high-quality seeds, based on local climatic and soil conditions, is key to successful planting. For example, in colder winter areas, cold-resistant varieties should be chosen, and in rain-prone areas, wet-resistant varieties should be selected。
02 seeding technology
Seed time
The timing of the planting of oily vegetables varies according to geographical location. In the yangtze basin, the appropriate planting time usually falls between september and october, while in the northern region, due to the relatively cold spring climate, it is usually chosen to sow in the spring。
Sowing
Vegetables are sowed in a variety of ways, often including sowing, stripping and planting. It is easy and easy to sow, but it is only necessary to spread the seeds evenly on prepared land and cover a layer of thin soil. This is done at a distance of 20 to 30 centimetres. In the case of seedlings, the seedlings need to be grown in the nursery before being transplanted to the field when they are of appropriate size。
Seeding
The determination of sowing levels requires a combination of seeding patterns and oily varieties. As a rule, the amount of land per acre is approximately 0. 3 to 0. 5 kg at the time of sowing, while stripping can be controlled at 0. 2 to 0. 3 kg per acre。
Field management
Saplings and seedlings
Intersapling and seedlings are carried out at the nursery stage to ensure sufficient space for each vegetable seedling. The process of seedlinging between two and three saplings of oil and vegetable seedlings, which are designed to remove dense or thin seedlings, ensures sufficient space for each seedling. When seedlings grow to between four and five leaves, seedlings are established, at which point between 20,000 and 30,000 healthy oil seedlings are usually kept per acre。
Fertilizer strategy
Different fertilizers need to be followed up in a timely manner during nursery, reed, flower and corny growth periods. Fertilizer is indispensable in the growth of oily vegetables. In addition to adequate application of base weights, there is a need to catch up at critical times. During seedage, 5 to 8 kg of urea per acre can be traced to promote healthy growth of the seedlings. And by the time of the rheumatism, this was the most critical stage in the growth of the oil and vegetables, requiring re-enactment. At this point, 10 to 15 kilograms of urea and 5 to 8 kilograms of potassium chloride per acre should be applied to ensure that the nutrient needs of the oily vegetable are met. In addition, fertilizing leaves such as potassium dihydrophosphate can be used during flowering and corneas during development, further increasing the saturation rate and the weight of 1,000 grains of oil and vegetables。
Water management
They're water-sensitive. Vegetable flowers are not drought- and flood-resistant and therefore have high requirements for water management. In the pre-growth period, in the event of dry weather, water should be poured in time to keep the soil wet and to provide a sound environment for the growth of oily vegetables. However, during flowering and corneas, attention needs to be paid to drainage and to avoiding the accumulation of water in the field in order to prevent disease。
Pest control
Integrated response measures, including rational planting and use of agents. Vegetable flowers may be threatened during their growth by diseases such as fungi, frost and aphids. We should take comprehensive measures to combat these diseases, such as rational planting, keeping the fields radiant and timely removal of leaves and strains. Once the disease has been detected, the corresponding microbicides should be administered immediately. Insects such as aphids can be treated with agents such as aphids。
04 time for harvest and attention
Angular fruit is the best harvest time when most of it turns yellow and seeds become hard. The harvest should be conducted in the clear weather so as to avoid harvesting in the rain that would affect the quality of the seeds. Post-harvest drying and storage are also required to ensure the quality of seeds。
In conclusion, the planting of oil and vegetable flowers requires careful operation and control at various stages, including fertilizer, water management, pest control and harvesting. It is only in this way that we can create a golden and luminous oil field that reaps full joy and wealth。
