The way of cultivated Land Protection of Catcher in Rye Field

"all things grow in the soil, there is earth and grain". Cultivated land is the most precious agricultural resource and important factor of production, and it is the livelihood of farmers facing loess.

The decline of cultivated land quality has become a huge stumbling block perplexing China's agricultural development in recent years. With the publication of the "Action Plan for Zero growth of Chemical Fertilizer use by 2020", saving water and fertilizer resources and improving fertilizer use efficiency have once again aroused hot discussion in the industry.

Low utilization rate of chemical fertilizer is the main cause of environmental pollution caused by chemical fertilizer, and leads to a series of environmental and food safety problems. Industry experts called for speeding up the promotion of slow and controlled release fertilizers to solve the problem of aggravated soil pollution and to improve the quality and efficiency of agriculture. Based on this, dozens of well-known universities and scientific research institutions inside and outside the United Nations have carried out technical research on new fertilizers with high efficiency and energy conservation, resource conservation, and ecological and environmental protection, and have successfully developed slow and controlled release fertilizers suitable for field crops with independent intellectual property rights, and built the world's largest slow and controlled release fertilizer production base of 1.7 million tons.

In order to adapt to the reality that the shortage of water resources in China restricts the development of modern agriculture in China, Kim Jong-da gathered the world's top experts to tackle key scientific and technological problems in the integration of water and fertilizer. On November 20, 2014, the 1.23 billion yuan raised was used for 600000 tons of nitro compound fertilizer in Guizhou and 400000 tons of water-soluble fertilizer project under construction. On May 28th, the Notel I project of 200000 tons of water soluble fertilizer project was put into production in Weng'an County, Qiannan Prefecture, Guizhou Province, so that China's water soluble fertilizer has really achieved large-scale development. and for the first time, China has a world-class quality of nitro fertilizer with obvious advantages in improving fertilizer use efficiency, saving agricultural water, reducing ecological environment pollution, improving crop quality and reducing labor force. It has laid a solid foundation for promoting the technology of water and fertilizer integration in China, and realized the magnificent turn of enterprise transformation and upgrading.

"strengthen the technology of integration of water and fertilizer, and promote the application and promotion of new fertilizers or soil remediation products, such as slow and controlled release fertilizers, water-soluble fertilizers, bio-organic fertilizers, and soil conditioners." during the two sessions this year, Wanlian, a deputy to the National people's Congress, proposed to speed up the application of the technology of integration of water and fertilizer to alleviate and regulate the quality of cultivated land.

The integrated technology of water-soluble fertilizer and water-fertilizer has the advantage that ordinary fertilizer does not have. Compared with the traditional planting method, the integrated water and fertilizer technology can concentrate on the supply of water and nutrients in the root layer, ensure the root wetting depth of vegetables and fruit trees, avoid the leakage and loss of water and fertilizer, and save water and fertilizer per mu. At the same time, the soil and air humidity are reduced, the diseases and insect pests are effectively reduced, and the amount of pesticides is also reduced accordingly.

By using the technology of integration of water and fertilizer, irrigation, fertilization and spraying can be completed automatically through the pipe network, which greatly saves the necessary labor in the process of agricultural production, which is 90% less than the conventional labor. Taking an 80-mu sugar orange orchard in Nanning, Guangxi as an example, conventional watering and fertilization takes 8 people 6 days to finish, with a total of 48 workers. After adopting the technology of integration of water and fertilizer, each watering and fertilization can be completed by only 2 people in 2 days, and the total labor is 4, which is less than the original 10%.

According to the data, with the application of the technology of integration of water and fertilizer, there is an increase of more than 200kg per mu of corn, 100kg of wheat mu, 1000 kg of potato mu, 30kg of cotton (seed cotton) mu and 500kg of vegetable mu. The commodity of agricultural products is excellent and the nutritional quality is improved. Both grain production and cash crop production have achieved effective cost savings and efficiency improvement. with the substantial improvement in the utilization level of water and fertilizer resources, water productivity has increased by 20%, and fertilizer use efficiency has also increased by about 20%.

The integrated technology of water-soluble fertilizer and water-fertilizer has become an effective breakthrough in the cultivated land quality protection policy of "realizing the transformation of agricultural production and management mode and taking the road of modern agricultural development with high output efficiency, product safety, resource saving and environment-friendly". The policy of "losing weight" of cultivated land has also been upgraded in the agricultural material industry.

Water-soluble fertilizer has fast fertilizer efficiency, fast dissolution and high utilization rate. Chen Qing, a professor at the School of Resources and Environment of China Agricultural University, believes that "popularizing the technology of integration of water and fertilizer is a systematic project, which will give birth to the technological integration reform of modern agricultural production." The data show that the utilization rate of conventional fertilizer in China is 20%, while the utilization rate of water-soluble fertilizer is 70%. The use of water-soluble fertilizer can not only save water, but also reduce the total amount of fertilizer. At the same time, the water-soluble fertilizer has high nutrient content and comprehensive nutrition, which can obviously improve the crop quality.

Water shortage and land shortage are the two major factors restricting China's agriculture. Saving water, fertilizer and land has become the urgent need of China's agriculture. With the intensive and large-scale development of China's agriculture, the transformation of agricultural planting patterns, and the acceleration of the process of land transfer, the proportion of agricultural scale operation is increasing, and the proportion of cash crops is increasing. The agricultural area of water-saving facilities in drip irrigation and sprinkler irrigation is expanding rapidly, and the integration of water and fertilizer has gradually become a "breakthrough" in the development of modern agriculture in China.

In the face of the current reality that China's agricultural water shortage is more serious than land shortage, Kim Jong-da responded quickly and actively carried out agricultural technical cooperation with Israel, using "desert agriculture" Israel as a model for water saving.

The Kim Jong Da-Livnat Agricultural Science and Technology Research Center, which was unveiled last year, launched a new round of cooperation with Israel's Arava Agricultural Research Center. Kim Jong-da Group conducted an experimental demonstration of water-soluble fertilizer for cucumber, cabbage and other crops in the greenhouse of the Arava Research Center. Arava is located in the Negev Desert in southern Israel, bordering on the southern Dead Sea, groundwater exploitation needs to be up to 1500 meters, and the water quality is high salinity, the average annual rainfall is only 30 mm, but the evaporation is 3000 mm, the natural environment of drought and little rain is not conducive to agricultural production. In order to build fertile land in the desert, farmers in Arava dug 30 × 30 cm grooves in the desert, buried them with compost and then covered the soil. Relying only on 25 to 50 mm of annual precipitation and some brackish water, the Arava region produces 60 per cent of Israel's exported vegetables and 10 per cent of flowers through a series of high water-saving technologies in modern agriculture, such as drip irrigation, integration of water and fertilizer, and desalination of salt water, with an annual export value of US $250 million.

As a leader in China's new fertilizer industry and a strong promoter of the technology of water and fertilizer integration, Kim Jong-da will continue to actively deepen exchanges and cooperation with Israel with the sense of mission and responsibility of the industry leader. We will promote cooperation between China and Israel in agricultural scientific research, personnel training, technology introduction, and achievements transformation. Through the joint efforts of both sides, we will make use of the advanced technologies and models in the field of agricultural production in Israel and other regions to develop technologies and products suitable for China's agricultural production, optimize the agricultural planting structure, and improve the quality of agricultural products and the efficiency of agricultural production. in order to further protect and improve the quality of cultivated land, realize China's agricultural modernization, and further promote the development of "smart agriculture".

"it can be said that the integration of water and fertilizer is not only a major technology for the development of modern agriculture, but also a 'No.1 technology' for the development of resource-saving and environment-friendly modern agriculture," said Gao Xiangzhao, chief expert on soil, fertilizer and water at the National Agricultural Technology extension Center. While constantly innovating and devoting himself to the research, development, popularization and application of high-efficiency new fertilizers, Kim Jong-da actively cooperated with the relevant aspects of water-soluble fertilizer integration to jointly explore the achievements, problems and solutions of water-soluble fertilizer promotion in China, promote the process of water-fertilizer integration in China, once again assume the historical task of leading industrial upgrading, and promote the development of environmental protection, green and efficient agriculture in China. Interpret the butterfly change from a simple agricultural manufacturer to "the world's leading plant nutrition expert and planting solution provider".
