How can we increase the yield of dry winter wheat on the hillside?

How can we increase the yield of small-scale fertilizers on the hillside arid winter wheat? China is a large agricultural country with many mountains and less land. In the north, there are many hillside or arid lands, and the natural conditions are relatively poor. Generally, the cultivable soil layer is 30-50 cm thick, the sediment concentration is relatively large, and the capacity of keeping fertilizer and water is relatively poor. The annual spring is mostly a dry season, generally There is no available groundwater. Under such harsh natural conditions, local farmers’ friends can only choose to use the base fertilizer at one time. Winter wheat generally produces about 300 kilograms per mu. How to take measures to increase the output of winter wheat has become a major event in helping farmers get out of poverty. As we all know, the growth period of winter wheat is relatively long, and its main requirement fertilizer peak period is the jointing and filling stage in the coming year. Therefore, it is the key to obtaining the high yield of wheat in order to maximize the nutritional requirements of the jointing and filling stages of wheat. In order to obtain high yield of wheat, we should make full use of both root fertilization and foliar fertilization to maximize the nutritional requirements of the jointing and filling stages of wheat. First of all, we have to do the article of foot root fertilization (basic and top dressing). In view of the local natural conditions, we did not follow up the possibility of returning green water and jointing fertilizer. We could only make full use of footpad fertilizers to extend the base fertilizer supply time to meet the nutrient requirements for the returning green jointing stage of wheat and achieve high yields. . We recommend to use Zhongde Long-acting Fertilizer 27-16-12 as the base fertilizer, which is suitable for the application of 15-25 kg/mu. Zhongde brand fertilizer is a good quality fertilizer. The outstanding characteristics of Zhongde long-acting fertilizer are: 55% higher total nutrient content and higher fertilizer utilization rate. Among them, nitrogen source mainly comes from large-particle urea, plus slow release agent. The nutrient release rate is moderate, and the early stage can avoid excessive release of pre-winter fertility and excessive consumption of nutrients, which can prevent the wheat seedlings from prospering and suffer freezing injury before winter. In the later period, it can maintain a stable and lasting supply of nutrients and avoid the premature decline of wheat defertilization. This long-lasting fertilizer is 20 days longer than the general fertilizer and its utilization rate is more than 20% higher than the normal small-particle urea fertilizer. It is especially suitable for crops that have a longer growth period like wheat and cotton. The use of long-term fertilizers in sandy soils with poor permeability and poor fertility can effectively reduce the loss of fertilizers. The advantages of long-term fertilizers and high utilization rates are most prominent. Note: In the base fertilizer, it is necessary to strictly control the amount of available nitrogen fertilizer. The reason is that increasing the use of nitrogen fertilizer in the base fertilizer does not guarantee more supply of nitrogen nutrition in the spring, because any kind of fertilizer has a certain reasonable preservation time in the soil. Fast-acting nitrogen fertilizers (including nitrate nitrogen, ammonium bicarbonate, small-particle urea, etc.) will be released more quickly and more quickly, causing wheat to prosper before the winter, excessive nutrient consumption, easily causing freezing damage, and greatly reducing wheat yield. Second, we must increase the amount of fertilizers for foliage. In the case of failure to improve root fertility, through foliar fertilization, we can meet the nutrient requirements of wheat at the jointing stage and filling stage to the greatest extent and significantly increase the yield of wheat. The advantages of foliar fertilization are: low dosage, low cost, high utilization rate, small labor, middle and old people can operate. 1, return to green joint period. In the case of no precipitation and topdressing of nitrogen fertilizer, it is recommended to spray urea and potassium sulfate solution 1-3 times, spraying once every 7 days, which can greatly promote the returning green jointing of wheat. 2, late childbirth. It is recommended to spray urea and potassium sulphate solution 1-3 times, spray once every 7 days, (every 30 pounds of water against urea 100 grams and 100 grams of Belgium's Potassium Sulphate) can play a role in rapid nutritional supplementation, not only Increase grain weight, improve quality, and reduce the risk of dry hot wind, generally can increase production 5-10%. Pay attention to the real item: urea must be selected from the first-class products produced by Dachang, in which the content of biuret should be less than 0.5%.

Softgels are widely used in prescription and OTC pharmaceuticals, as well as nutraceuticals for their improved bioavailability, ease of swallowing, positive consumer response, reduced odors/flavors, extended shelf life and flexible product formulation options.

Depending upon the production criteria, the gelatin shell may include minor additives such as coloring agents, flavors, sweeteners, preservatives and even various medicines. Enteric coating is now available for softgel capsules for certain applications where delivery of the active substance should bypass gastric juices in the stomach to be absorbed in the intestinal tract. For example, fish oil, garlic, peppermint oil and oregano oil are examples of enteric coated nutritional products. The coating helps mask unpleasant odors and tastes, and prevents irritation of the stomach lining.


Hard gelatin capsules are a preferred oral dosage form in pharmaceutical and nutritional applications as they are neutral in taste and very easy to swallow.


We specialize in high performance tablet products including controlled/time release solid dose products. Inovobiologic`s scientists are equipped to offer accelerated new product development and provide consultation.
