In recent years, extreme weather has become more frequent, and disasters such as cold, drought, and squalor have occurred frequently. The increase in pests and diseases coupled with the lack of effective disaster prevention and mitigation techniques has led to more and more restrictions on high yield of rapeseed. The pure natural plant growth regulator from Germany contains a variety of plant endogenous hormones, which can effectively regulate the balance of plant nutrition and hormones, and has affinity with plants, and has many functions and safety. It is a farmer friend. Get the secret weapon of high yield of rapeseed.
Bio-cultivation
The high yield of rapeseed and the cultivation of strong seedlings are the basis. In the case of drought after the autumn sowing, it is easy to appear the phenomenon of lack of seedlings and ridges, uneven emergence, and weak seedlings. Bi-energy can promote root development, give plants a strong root system, induce crops to produce a large number of cytokinins and vitamin E, improve the ability of rapeseed to resist drought, and make Miao Qi Miao Zhuang. In the rape seedling stage (4 leaf stage), it can be combined with insecticides for controlling pests such as cabbage, aphids and other pests. With the protection of 7500-10000 times liquid leaf spray, it can improve the quality of seedlings, the petiole is short and thick, the leaves are dark green, no pests and diseases, promote branching, and promote plant growth.
For seedling transplanting rapeseed, if the slow seedling period is too long, it will seriously affect the early growth of rapeseed and reduce the yield of rapeseed. It can be sprayed with 15000 times of liquid on the foliar surface after transplanting, which obviously shortens the time of slow seedling and lays a foundation for cultivating strong seedlings.
Easily solve the freezing damage of rapeseed
Rapeseed is basically based on vegetative growth before winter, and begins to divide flower buds. Over-wintering temperatures often cause different degrees of freezing damage in rapeseed leaves. Defensive measures In addition to timely filling the winter water, the roots of the soil, and the cover of the fertilizer, the leaf surface sprayed with the 5,000 times liquid + chitin, can improve the cold resistance of rape, and has the dual effect of preventing the occurrence of freezing damage and recovery after freezing. . In the high-efficiency cultivation mode of “Northern rapeseed north shift†in Gansu Province, the pilot application of Bihu has achieved gratifying results and can significantly improve the cold tolerance of rapeseed.
Control "flowers and not real"
The main reason why rapeseed is not flowering is the lack of boron in flowering period. The effective measure to prevent rapeseed is to supplement boron, and to ensure sufficient supply of boron nutrition during rapeseed. It is advisable to spray borax solution with a concentration of 0.02% once in the seedling stage, the bud stage and the initial stage. It can be mixed with 15000 times of Bibao and high-quality and high-content boron fertilizer to increase the absorption and utilization rate of boron fertilizer and improve the seed setting rate.
Inhibition of sclerotinia
Sclerotinia sclerotiorum is the most important disease in rapeseed production, which can reduce the yield of rapeseed by 1-3%. For the prevention and treatment of the medicament, the compound preparations such as Bishui + Sclerotium, carbendazim and thiophanate are used, and the medicine is used from the initial flowering to the full flowering period. Bibao can improve the efficacy of pesticides, inhibit the spore germination of pathogens, and promote cell repair after disease. Gansu Provincial Agricultural Reclamation Research Institute: Bi-energy can significantly improve the disease resistance of winter rape. The incidence of Sclerotium disease in Bixin treatment was only 23.8%. In contrast, in the control area, the symptoms of Sclerotinia sclerotiorum were obvious, the leaves were dry, and there was a significant premature aging trend, with an incidence rate of 42.5%.
Increase rapeseed yield
Under the condition of reasonable close planting, the key to increase the number of pods per plant is to increase the number of branching pods. Bijian nursery seedlings increased the number of main stem leaves, increased branching rate and promoted flower bud differentiation, thereby increasing the number of pods.
In the buds from the buds to the flowering stage, spraying the compound liquid of Bi-protection and boron fertilizer can promote the flower, the angle is large, the pod is large, the grain is full, the number of pods of the pods is reduced, the seed setting rate is increased, and the yield is increased. Up to 20% or more.
