(I) Application after mixed fermentation with organic fertilizers. Organic fertilizers are rich in organic matter, carbonic acid, and a variety of organic weak acids that make insoluble phosphates soluble phosphates. At the same time, organic fertilizer and phosphorus fertilizer can greatly reduce the contact surface between phosphate fertilizer and soil, thus reducing the fixation of phosphorus on soil. Stacking methods: In the two weeks before application, add 1 to 10 parts of phosphate fertilizer and mix 10 to 20 parts of organic fertilizer. Mix well, seal mud outside to prevent loss of fertilizer efficiency. According to the Zhucheng test, superphosphate and organic fertilizers were used in wheat fields after being mixed and fermented, which was 23.1% more efficient than direct application to wheat fields. (B) in combination with nitrogen fertilizer, potash fertilizer and zinc fertilizer. According to the requirement of nitrogen, phosphorus, potassium, zinc and other nutrient elements in wheat, when applying phosphate fertilizer, the scientific formulation of nitrogen fertilizer, phosphate fertilizer, potash fertilizer, and zinc fertilizer can effectively supplement the deficiency of soil nutrients and increase the utilization rate of phosphate fertilizer. 20 to 30%. The proportion of its formula application: general high-yield wheat field per acre basis quality organic fertilizer 4000 kg, standard phosphate fertilizer 50 kg, standard nitrogen fertilizer 30 kg, standard potassium fertilizer 12 kg, zinc sulphate lump mu application of 1.5 kg of zinc sulfate; High quality organic fertilizer 3000 kg, standard phosphate fertilizer 50 kg, standard nitrogen fertilizer 35 kg, standard potassium fertilizer 8 kg, zinc sulfate 1 kg is appropriate. (c) Adopt a centralized application method. The concentrated application of phosphate fertilizer can effectively reduce the contact surface with the soil, thereby reducing the effective phosphorus in the phosphate fertilizer is fixed by calcium, magnesium, iron, aluminum and other elements in the soil. Especially in yellow soil, red soil, calcareous soil, yellow soil, shajiang black soil and other types of clay soil applied to phosphate, more easily fixed by the soil. Studies have shown that: Phosphorus enrichment bar application can increase the utilization rate of 28%, compared to the application of appellation can increase wheat yield by 11.8%. Method of Application: Before planting wheat, soak the first 8 to 10 centimeters of phosphorus fertilizer with a planter according to the sowing distance, and sow the second planter so that the seeds and phosphorus are staggered by 1 to 2 centimeters to prevent damage. bud. (d) Phosphate fertilizers should be used for local conditions. In order to increase the utilization rate of phosphate fertilizer, phosphate fertilizer should be used for soil. In neutral and calcareous alkaline soils, the water-soluble superphosphate is used. The superphosphate is weakly acidic and can neutralize the alkali in the soil. In the acidic soil, the weak alkaline calcium magnesium phosphate is used. The acid soil is used. Basic fertilizer can not only enhance its fertilizer efficiency, but also neutralize the acid in the soil to avoid the acid damage to the wheat root system. (5) The amount of phosphate fertilizer should be appropriate. According to the result of phosphorus application test in medium-fertility wheat fields in Changle County, the yield of wheat per kilogram of standard phosphorus fertilizer decreases with the increase of the amount of phosphate fertilizer. However, if the dosage is too small, the yield per unit area is not significant, and 55 kg per acre is used. The best increase in production results. Generally, the amount of mu applied in wheat fields is 50-60 kg. (6) Spraying on the outer leaves. During the jointing of wheat to booting and grain filling, superphosphate 2 to 3 kg plus water to open, filter residue, mixed into the fresh water 50 to 60 kg, in the jointing of wheat in the booting and filling period, can increase production by 4 ~6%. Or spray 0.2% of potassium dihydrogen phosphate solution, 60-80 kilograms per acre per spray, spraying three times, there is a strong anti-downside effect of strong stalk, can increase production 4.6 to 8.1%. The root spray should be selected after noon on the sunny day after 3 pm or on a cloudy day. Spray the wheat plant with a sprayer to “split a button and penetrate all sides†to spray the fertilizer on both sides of the plant. .
1.Rabbit is an excellent high quality, lean protein option for dogs and cats. For most of our household pets, rabbit would be one of their primary sources of nutrition if they were allowed to hunt their own meals. Rabbit meat is a great source for vitamin B-12
andB-3. Rabbit is also high in selenium and will provide your pet with a good source of phosphorus.
2.Dehydrated rabbit ears are like potato chips to dogs. The fur does provide dietary fiber and they are a high value treat for most dogs. Rabbit ears are the treat of choice for many sport dogs. Rabbit ears are available individually or in sets of 4. Side note: Feeding rabbit does not alter natural prey drive. If your dog or cat gets along with your pet bunny, feeding rabbit meat will not change their relationship. At the same time, we are sensitive to owners who choose not to feed rabbit to their pets. There are plenty of other options to offer variety
