Early pursuit of fat. When the temperature rises above 10 °C, the rapeseed is continually twitching, which is the booming fertility era in which rapeseed has the fastest development and the most fertilizer. Therefore, it is necessary to reapply the manure and cooperate with the spraying of photosynthetic nutrient film fertilizer, which can help the plant to absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit, and benefit from one application for the whole year.
Beware of water damage. In spring, there is more rain, the soil is sticky, and the air humidity is so bad that it is extremely unlucky to the roots. Rapeseed is the most scarred crop, and the accumulated water will form water, rotten roots and dead seedlings. To this end, we must clear the "three ditch", clear the ditch after the rain, to truly achieve the ditch and the same, rain and live in the field.
Prevent pests and diseases. Promote comprehensive prevention and control techniques, and do our best to prevent and control. Spraying a new high-fat film 600 times before the onset of disease can automatically form a polymer protective film that is invisible to the naked eye to optimize the water absorption, breathability and light transmission quality of the plant. Blocking pests and smuggling signals and weakening the media to resist and defend against natural environmental disasters. When using pesticides in the early stage of the disease, they must be used alternately in turn. When using pesticides, they should be used together with new high-fat membranes to control the volatilization of pesticides, prevent rainwater from scouring, reduce the dosage per acre by half, and improve the control effect.
