In order to obtain high quality and high yield of sesame, scientific and rational fertilization is the key. The production practice proves that the focus of fertilization on sesame lies in the timing and method of grasping, requiring that the seedling fertilizer should be “earlyâ€, the bud fertilizer should be “smartâ€, and the flower fertilizer should be “heavyâ€. Let’s talk about the specific method for reference.
Early application of seedlings and sesame seeds Because the seeds are small, and often the application of nitrogen fertilizer is too much at the bottom, it is easy to make the seedlings grow and form high seedlings. Therefore, in conjunction with sesame seedlings morning, early Dingmiao, once applied early to see Tony-based fertilizer quick result Miaofei, Shi Miaofei good health is premature sesame longer important measures. It is better to dilute the decomposed manure or urea in the seedling stage. Generally, after applying the seedling, the urea should be applied 2 to 3 kg per mu . When the drought is heavy, it must be drought-resistant and then diluted or diluted with thin human excrement. For the poor seedlings, it is necessary to adopt the method of “opening special meals†to pursue the application of seedlings . Sesame seedlings should be applied to the roots according to the shallow characteristics of the sesame roots.
The buds of sesame and sesame seeds are entering the flower bud differentiation stage, when the vegetative growth and reproductive growth of the plants are simultaneous. Therefore, the application of bud fertilizer is of great importance to the high yield of sesame. Squaring nitrogen-based fertilizer generally, phosphorus and potassium is the auxiliary. When fertilizing, the strips can be applied or spread at a distance of about 10 cm from the sesame plant , and applied to a soil layer 10 cm deep to absorb the roots and apply the soil after the application; for the spread, the decomposed cake fertilizer or The granular urea is mixed into the finely divided soil and mixed well and applied. After fertilization, the cultivating loose soil is used to cover the soil. When the weather is dry, water should be sprayed after application to fully exert the fertilizer effect. Pour method may also be employed, i.e. urea per acre with 4 to 6 kg 200 kg watered pour in sesame stump portion. In addition, boron fertilizer should be added as appropriate for boron-deficient areas and boron-deficient soils.
Re-application of flower fat sesame seeds into the flowering stage grows most rapidly, and the nutrients absorbed in this period account for 70% to 80% of the whole growth period . In order to meet the needs of plant growth and development, the sesame grows vigorously, accumulates more photosynthetic products, increases the number of flower buds, and the long-term stability does not prematurely decay, so that the grain is full and full, and the flower fertilizer must be re-applied. At the same time, the lateral roots of the flower pod stage have begun to form in large quantities, the absorption capacity of the root system is enhanced, the growth rate of the plant is accelerated, and the demand for nutrients is also significantly increased. Thus, a flower pods to reapplying fertilizer, typically urea per acre with well-5-8 Watered kg to 200 kg pour sesame stump portion, may be administered Cake retting, manure and other people. In addition, from the beginning of the flower to the full bloom period, the root dressing can be carried out by selecting the sunny afternoon and using 0.3% potassium dihydrogen phosphate solution. Spray on the front and back of the blade, every 5 to 6 days, and spray 2 to 3 times.We have been manufacturing and selling red light therapy device for 8 years and supply over 98% of these products to the European and American markets.
