Under the freezing night, the weak wheat seedlings are used to return to the green fertilizer . The late weak wheat seedlings are deeper into the soil and have a lower degree of differentiation of the growth cones. The plants have less nutrients stored in the plants, and are susceptible to freezing damage in early winter and early spring. Ruomiao relatively thin due to late, breathing ability, do not have a large number of topdressing fertilizer, topdressing provide a small amount of nitrogen fertilizer available vaccine and an appropriate amount of promoting root development in order to accelerate the growth of wheat seedlings with fertilizers and then gradually increased, it may be at the beginning of reviving acres chasing 100--150 kilograms chicken manure, manure and phosphate fertilizer, the fertilizer is administered preceded triturated prevent pressure seedlings.
   Mung bean fertilization. The land where the mung bean is grown is mostly thin and dry, and the application of organic fertilizer, compound fertilizer or chemical fertilizer will have obvious effects of increasing yield. Mu Fertilizers 1500 - 2000 kg decomposition of organic fertilizer or ammonium sulfate, 5 kg Mushi types of fertilizer, superphosphate 15 kg fit, 5 kg of potassium sulfate or potassium chloride, in that after flowering per acre with 0.2% - 0.3 % of potassium dihydrogen phosphate solution to spray 50 kg, once every two days to close off a pod before spraying, stimulation is more effective.
   Sunflower high yield fertilization method . Fertilization should master the principle of “applying the base fertilizer, applying the fertilizer, and applying the fertilizerâ€. Combined with deep plowing soil preparation administered quality manure 3000--5000 kg / acre, applied types of fertilizer DAP 10--20 kg / acre, applied potassium Lot 2 kg / acre potassium. According to the soil test results of each region, appropriate application of micro-fertilizer. Before squaring dressing should be combined cultivator topdressing urea 10--15 kg / acre, 10 cm deep application better.
   Sesame high-yield fertilization method. The base fertilizer can be selected from the formula of 500 kg of soil- fertilizer per mu , 8 kg of nitrogen and 5 kg of phosphorus . If the K content in soil is low, then the formulations may be added potassium basal 7--8 kg / acre; sesame dressing The required peak high nitrogen characteristics, sesame single stalk in the beginning of flowering and budding, branching at branch sesame In the appearance period, urea was applied at 8 kg / mu. Sesame is sensitive to boron, so spraying 0.2% borax nutrient solution on the frond of the initial flowering period is also an effective measure to increase the yield .
   The fertilization characteristics of castor. The base fertilizer of ramie is mainly composed of manure, compost, ash manure, green manure, superphosphate or a small amount of ammonium phosphate, supplemented by a small amount of nitrogen and potassium fertilizer. The amount of an organic fertilizer per acre 1000--1300 well-pounds, phosphorus (P2O5)) 4 - 5 kg. Potash depending on whether soil potassium deficiency, lack of potassium sulfate or potassium chloride may be mu 5--7 kg. Castor dressing depends on the circumstances, if the base fertilizer, manure insufficient seed, seedling, the potential length of branching is not busy, a small amount of the available nitrogen, phosphorous or nitrogen and phosphorus compound fertilizer (such as ammonium) for topdressing, pure Nitrogen ( N ) 3 - 4 kg, phosphorus ( P2O5 )) 2 - 3 kg / mu. Set dressing in the seedling stage, the center of the inflorescence appears, not too late, or improve productivity, and enhance the resilience of the late castor unfavorable.
Microscope Slides And Cover Slips
1. The glass slide is used to put the sample to be tested, and the cover glass is covered on the sample to be tested.
2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects
6. The cover glass is square, the slide glass is rectangular, and the width is longer than the side of the cover glass.
