Seedlings and transplanting. And time seedlings, fixed seedlings, can cultivate strong seedlings, rational use of soil resources. Seedling transplanting or direct seeding rape, when the seedlings have two true leaves, it is necessary to start the first seedling, pull out the weak seedlings, and keep the distance between the seedlings more than 1 inch, so that each seedling can obtain ventilation and light transmission conditions and sufficient nutrient area.
Directly sown rapeseed seedlings were set when the seedlings had three or four true leaves, and the seedling retention density was determined according to the type of rapeseed, variety characteristics and sowing method.
The quality of transplanting rapeseed directly affects the survival and later growth of rapeseed. Generally, transplanting begins 30-40 days after sowing with six or seven leaves. Water once before seedling raising to reduce seedling damage.
When transplanting, robust seedlings should also be selected, and those with strong leaves, short and thick petioles, low leaf parts, short and thick roots, and have not suffered from diseases and insects for transplanting. Regardless of the direct seeding or transplanting of rape fields, should be checked frequently at the seedling stage, where there is a lack of seedlings, should be immediately transplanted and replenished seedlings to ensure that the whole seedlings.
Cultivating soil. Cultivating can remove weeds in the field, reduce nutrient consumption, prevent and control pests and diseases, and combine cultivating soil with cultivating work, which can keep warm and freeze and prevent lodging. Before winter, the grass should be hoeed 1-2 times, the first time should be shallow, to remove weeds in the field; The second time is slightly deeper, which facilitates root development.
In this tillage, combined with fertilization in areas prone to frost damage, the soil between the rows should be covered around the plants, so that the cultivated soil is slightly higher in the north and slightly lower in the south, so as to be easy to accept sunlight and reduce the threat of cold winds.
Clear ditches and drain water to prevent drought and flooding. In areas with more rain and snow in winter and spring, in autumn, growers should clean the furrow to remove stagnant water, if the soil has too much moisture, it is easy to freeze in winter, destroying the development of the root system, and the leaves of the plant are also easy to yellow, poor growth.
At the same time, the soil is frozen and loose, and the soil on the edge of the furrow is easy to collapse at the bottom of the ditch, which makes the drainage poor and causes waterlogging. Therefore, in areas with more rain, it is necessary to check and clean the ditch at any time, so that the deep ditch is high, the ditch is unblocked, and there is no water accumulation in the field.
Rapeseed harvest and high yield, autumn field management needs to do a good job these points are introduced here, I hope it will be helpful to everyone.
