The content of erucic acid and glucosinolates in the low rapeseed pods is low and the quality is good, but the yield is low. According to the variety characteristics, strong seedlings and thinning cultivation are conducive to high yield. Ganoherb International Inc. , http://www.ganoherb.us
Strong seedlings and thin plants promote early-onset cultivating seedlings with 30 to 35 days of age, thick green leaves, appropriate young and tender, thick roots, and no pests and diseases. From late October to early November, the tape was transplanted with fertilizer. Strong seedlings and sparse planting, spacing 45 to 50 cm, plant spacing 20 cm, planting 7000 per mu. After planting and pouring root water.
Rational fertilization for high yield per acre Daejeon base ammonium bicarbonate 40 kg, superphosphate 40 kg, potassium chloride 7.5 kg. After the live tree, 750-1000 kg of thin human excrement per acre or 10-15 kg of ammonium bicarbonate is used as seedling fertilizer to promote autumn hair and build a high-yield shelf. Applying wax fertilizer on the basis of early application of Miaofei, mainly organic fertilizer. During the period between Osako and the Great Cold, 1,000 to 1,500 kilograms of manure or manure was applied per mu, ensuring that the winter prospered the spring. When the height is 3 to 5 cm, 750 kg of excrement or urea 7.5 kg per mu is applied.
The application of boron fertilizer to promote healthy growth of double-low rapeseed sensitive to boron should be given enough boron fertilizer. 500 grams per acre mixed ash with borax, when transplanted for root pressure application. In areas with severe boron deficiency, such as mountainous areas and semi-mountainous areas, 50 kg of 0.2% borax solution is sprayed per acre during the convulsive period. The spraying of boron fertilizer during the flowering period combined with the control of Sclerotinia sclerotiorum prevents “flowering but not realizingâ€.
Disease prevention and control Insect protection harvest pay attention to the control of aphids, cabbage caterpillars. The main prevention and control of aphids in the early stage. The initial flowering period and full flowering period focus on the prevention and control of sclerotinia, attention to clearing the ditch, reducing the humidity in the field.
