In recent years, due to lack of superior production measures, commercial rapeseed cannot reach high quality standards and can not be comprehensively used. Farmers also experience the benefits brought by high quality and high prices, and lose the true significance of high-quality rapeseed production. The following are some of the measures for the production of high-quality rapeseed with good quality and high yield.
I. Good quality cultivation measures
1. Isolation and contiguous planting. Rapeseed is a cross-pollination crop, which is easy to cause biological mixing and reduce quality through wind, insects and other media. Therefore, high-quality rapeseeds should preferably be contiguously planted with isolation zones around the planting area to remove cruciferous crops that bloom at the same time as rape. Segregation methods: First, space separation of more than 1,000 meters; second, isolation by natural barriers such as villages and forests; third, isolation of high stalk crops; and fourth, artificial barrier isolation at flowering time.
2, remove the seedlings. The seedlings of rapeseed and cruciferous crops are mainly seedlings that were naturally scattered in rapeseed fields and cruciferous crops last year, or self-seeded seedlings that were introduced using artificial factors such as farmyard manure and agricultural machinery. The method of clearing the self-producing seedlings: First, implement the paddy-crop rotation or the following year planting; Second, the application of decomposed farmyard fertilizers; Third, the farm tools should be cleaned before use; Fourth, carefully observe the rapeseed growth in each period and found that the spontaneous seedlings were removed in time, with the planting area. Rape seedlings transplanting should pay special attention to seedbed seedlings prevention, because seedling seedlings and nursery rape emerged at the same time, while growing, it is difficult to distinguish between removal.
Second, the high-yield cultivation measures High-yield high-quality rapeseed cultivation and conventional varieties of rape are basically the same, in addition to the timely implementation of early sowing, nurturing strong seedlings, appropriate age transplanting, reasonable dense planting, scientific fertilization and other measures, it is necessary to be particularly raised is to pay attention to pest control and Application of phosphorus, potassium and boron fertilizers.
1. Prevention and control of pests and diseases. In the 1980s, high-quality rapeseed varieties cultivated in China were poor in yield and pest resistance (mainly “double-low†rapeseed). Through nearly 20 years of efforts, breeders have reached or exceeded conventional varieties. Quality rape, but there are still some varieties of resistance can not be compared with, for these species, we must pay special attention to control seedling cabbage caterpillar, aphids and late Sclerotinia.
2, the application of phosphorus and potassium fertilizers. High-quality rapeseed is more sensitive to phosphorus deficiency. Potassium is an important element in forming stems and promoting nutrient operation. Attention should be paid to the application of two kinds of fertilizers.
3, the application of boron fertilizer. Rape is a crop that is sensitive to boron, and high-quality hybrid rapes are more sensitive. Boron deficiency can cause "flower failure but not real" phenomena, affecting yield, and severely affecting the yield of rape. At the same time, it also has high quality rapeseed quality. influences. The boron-deficient soil with boron content less than 0.5 mg/kg in our city accounted for 79.3% of the cultivated land area. The sensitive boron-deficient soil with sensitive boron deficiency symptoms accounted for 22.8% of the boron-deficient soil. Therefore, the cultivation of high-quality rapeseed should pay attention to the application of boron fertilizer, mainly the application of basal fertilizer, the initial flowering period and full flowering foliar spray.

Plant Extract has been classified to two types by extraction methods including the standard plant extract and ratio extract in china local market. If we want to distinguish between the two types ,we can see from the ingredients that we should pay attention to. The standard plant extract will be tested of its special ingredients that in the product maybe by HPLC, UV, TLC etc,but for the ratio extract,we don't pay attention to the special ingredients that in it or not,not to mention the purity of one ingredient.if you still confused about the cllasfication,pls contact us to know more.
