Moss is the most critical factor in the life of rapeseed, and it is also the last rhizosphere top dressing. When the rapeseed grows to the bolting stage, the growth is accelerated, and the nutrient supplement is urgently needed. The application of the moss fertilizer can effectively promote the vegetative growth and reproductive growth, making it flourish, growing vigorously, and the growth phase is up to the high yield standard, and the fertilizer is not applied. The field of rapeseed increased production by more than 20%. Therefore, applying rapeseed to rapeseed is an important technical link for high yield.
(1) Application time of moss fertilizer: The initial rapeseed is slower, and after the height of the moss is 10 cm, the growth is accelerated. Because of the absorption and transformation process after the application of the fertilizer, the moss is exposed (the young leaves are exposed to the heart) to the height of the moss. The period of centimeter is determined as the best application period for the fertilizer. If the moss height reaches 20 cm, the main moss is tender and the branches are pulled out, the field operation is easy to cause plant injury, and the effect is late, and the effect of increasing the branch angle is small. For the three types of seedlings and the obvious de-strength seedlings, it is necessary to catch the moss; for the strong growth, the high-yield fields with a production level of more than 200 kg can be postponed until the height of the moss is 10 cm.
(2) Fertilization amount: The general dosage of rapeseed fertilizer is 10-20 kg of standard fertilizer, which can ensure the growth promotion and avoid overuse, resulting in the growth of tenderness, late grafting and the consequences of increased pests and diseases. The economical application of fertilizer can be guaranteed. See the early application of the moss should be heavy, 17.5 ~ 20 kg of fertilizer per acre; for the amount of wax fertilizer, the peak of the peak of the moss peak should be light, with 10 to 15 kg of fertilizer per acre is enough.
(3) Types of moss fertilizer and application methods: The types of application of moss fertilizer are mainly fast-acting nitrogen fertilizer, and should be applied with water when the weather is dry. In addition, the fertilization method should be determined according to the type of fertilizer. Fertilizers such as ammonium bicarbonate and ammonium sulfate are volatile and should be used for acupoint application and deep application. The urea which is an organic nitrogen fertilizer can be directly applied or watered before the rain and the rain gap, but the application time is 3 to 4 days earlier than the ammonium carbonate for conversion.
(4) Matching technology of applying fertilizer: The rapeseed applying the fertilizer has strong growth and good luxuriance. The vegetative growth and reproductive growth are stronger than the average field. To fully exert the effect of increasing the yield of the fertilizer, it is necessary to grasp the later stages. Matching technology. First, after applying the moss fertilizer, combined with weeding and cultivating soil, carry out the clearing of the ditch, and strictly prevent the root damage; secondly, we must grasp the prevention and control of the sclerotinia disease, spray the carbendazim solution in the flowering period to control the disease; It is sprayed with 2% potassium dihydrogen phosphate solution 1 or 2 times before and after the final flowering, and the de-fermented field should be mixed with 2% urea solution.
