Apply Base Fertilizer to Promote the Early Development of Rape

(1) Transplanting at the right time should not be too late. Early and timely planting is conducive to making full use of the appropriate temperature in the late autumn and early winter, and strives to grow early in the morning. The general requirements are to be planted in the middle and late October, and the Sanmian field will not be allowed to pass until about the beginning of November.

(2) Narrow and narrow narrow-row row cultivation. Paddy field rapeseed soil has poor viscous weight, poor drainage and air permeability, and it is more important to promote the narrow and narrow rows of deep narrow-channel cultivation to prevent rot-root dead seedlings during rainy weather, and to lay a foundation for improving ventilation and light transmission, promoting individual development and improving population structure. Paddy rice field width 1.4 meters, the width of the car ditch, the depth is 20 cm, the ditch and waist ditch depth, width are 30 cm design, gully scatter and sprinkle on the surface, leveling fine. When transplanting, wide row spacing is 40 centimeters, narrow row spacing is 20 centimeters, ditch is transplanted, and each dribbling ditch is 6 pieces. The narrow row is arranged at the edge of the trunk. Rape seedlings are planted at a plant spacing of 20-22 cm, 0.9-1 million per acre. Strains.

(3) To plant large seedlings. When transplanting, it is required to meet the criteria of “6-inch seedling height, 6 green leaves, 6-mm thick root neck”. Do not plant weak seedlings, and do not mix small and large seedlings. When transplanting, plant fresh seedlings. Do not plant overnight seedlings. Starting from the seedlings, while transplanting, while soil, while watering, will help shorten the return period. To plant the root seedlings, do not plant "hanging root" seedlings to prevent them from hanging out. (4) Implementing ditching and planting. Earthy viscous rice fields, if they are planted and transplanted on a rainy day, they are likely to cause water accumulation in the seedlings and are prone to black root rot after transplanting. However, if they are planted in open trenches and then mixed with manure, the roots will be rooted. The soil is cool and breathable. After transplanting, it will return to green and will not appear dead and rotten.

If rot-root dead seedlings are found after transplanting, they can be drained in time to reduce the moisture in the cultivating layer; cultivating in the rows, renewing the air in the roots to eliminate toxins; removing the dead seedlings to make up the plant to prevent ridges and ridges; Promote comprehensive remediation measures such as new roots.
