The "root irrigation" is to directly fill the roots of fertilizers, water and medicines needed by plants to form nutrients in the root wrapping area. Popular metaphor: that is, the "nutrients" required for plant growth are sent directly to the "tummy." That is, infusion of injections for plants. What are the benefits of using this method? Obviously, the liquid is injected into the roots of plants, so that the fertilizer, water, and medicine needed in the roots of the plants can be maximally applied to the plant roots by the effects of liquid fertilizers, pesticides, and fungicide, and the effects are even more special and obvious.
At present, the problems caused by water shortage in western China are quite serious. Due to lack of water, plants are degraded and dust storms are increasing, increasing and causing huge losses.
There are now some drought-resistant measures that can solve some of the water shortages. Like rainwater harvesting, the use of groundwater, and the use of plant anti-drought and water-retaining agents, but these methods only solve local conditions, but the planting of plants in areas with severe desertification and desertification cannot develop the western economy from the fundamental ecological environment. This requires us to Every effort must be made to save water. The "root irrigation" water-saving water used in constructing a green barrier is used at the most critical point, minimizing the normal water requirement of the plant to solve the water-saving problem. So how can we easily perform root irrigation? From this line of thinking, Gansu Zhangye New Type Finishing Gun Company after years of arduous exploration, research and create a series of LYJ multi-functional drug fertilizer gun. The product was awarded two national patents and was awarded a major science and technology promotion project by the state. It can solve the inconvenient and difficult problems of root irrigation and is a major revolution in root irrigation technology. He Kang, former Minister of Agriculture, praised and said: "Small inventions. Big role" drought-resistant water-saving fertilizer gun simple and durable, practical and strong, the biggest feature is to use it to give full play to irrigation and water-saving advantages. It can be used with a variety of sprayers, using air pressure to directly inject fertilizer and water into the plant's root system. It can be used to grow grain and oil, vegetables, and trees throughout the country. Water-saving fertilizer guns can be used in long-term arid climates according to the size of the plant. Next, put a 100-200 times more water-absorbing water-retaining agent into the root zone 10-30 cm, and let it be in the root zone of the arid plant to form a root bag that will not be evaporated, lost, or leaked. It is not afraid of drought and can absorb warm water around its root zone. It can be released slowly when it is needed for normal growth of plants. The time can be up to 3-8 months, and trees can be planted in desert areas as long as 5 - After 6 months of water injection, the planted tree can survive on its own. This is the advantage of root irrigation. It avoids the irrational and ineffective activity of the tree. It is applicable throughout the country and has been successfully used in western Gansu Province, Ningxia Autonomous Region, and Inner Mongolia Autonomous Region. The characteristics of the climate drought in Hohhot is to solve the spring drought of crops. With water shortage, continuous drought in summer and autumn, and drought and seedling protection in ecological construction, the LYJ multi-function top dressing guns were introduced 40,000 times in 1998 and 2001 respectively. The promotion and application of the LYJ in the whole city are very effective. To the important role, the attention of leaders at all levels and the majority of farmers. The application effect in the city is mainly the following three aspects: First, the spring drought water point seed, taking corn as an example to save water 80%, fertilizer 30%, 2 labor per acre. Second, the drought and drought in summer and autumn to make water and drought, taking corn as an example, 0.7 square centimeters of water per acre, delaying the dry crops for 8-10 days, 80% more than drip irrigation. Fertilizer 40%, increase production by 13%. Third, the ecological construction of tree seedling drought, take Pinus tabulaeformis slender seedlings as an example, each plant added appropriate amount of plants drought and water conservation at the same time Irrigation, in 2001 drought-saving 80%. In the spring drought, when it is flooded once, and water is replenished twice in summer and autumn, the seedlings can survive and grow. Comparing water-saving fertilizer gun root with other irrigation methods, it has more water than spray irrigation and drip irrigation, and the cost is quite low, which is one thousandth of the cost of drip irrigation. The use of water-saving fertilizer gun per acre root irrigation equipment investment of less than 2 yuan, to adapt to China's national conditions, public opinion, more suitable for the country's investment in returning farmland to forests, building green channels, desertification afforestation. At present, the western region of China is contemplating the climax of returning farmland to forests for ecological engineering construction. If all aspects of financing are not underestimated, this "small invention" of water-saving and drought-reducing drug fertilizer guns will only need 5 to 10 years to fully promote water-saving and drought-resistant fertilizers. The "big role" of gun-root irrigation technology is to ensure the survival and normal growth of afforestation in arid regions. The green barrier will surely be built, and it can save the country hundreds of billions of yuan in investment and provide a national solution for desertification. contribution.
This product contains two packs of 100 pH strips, 200 strips in total. Each strip is made of premium grade litmus paper intended for universal application.
