Poplar efficient compound cultivation mode

In the same land management unit, following the principles of ecology and guided by ecological economics, the forestry and agriculture (including animal husbandry and fisheries) are purposefully organically combined, and farmland forestry networks as the main body, combined with various agricultural and forestry intercropping models. Belts, nets, films, and dots are reasonably configured in space at a certain timing, and the unified and orderly use of land is highly efficient. It is a labor-intensive intensive management method that fully utilizes natural forces. When the forest is organically combined with animal husbandry and fishery, it is also consistent with the circular economy.


Project Demonstration and Promotion The project team of Nanjing Forestry University has implemented the “Hengxian County Agriculture and Welfare Project” since 2009 and cooperated with the Agriculture, Animal Husbandry and Fishery Bureau of Suining County to carry out the promotion of efficient cultivation technology of Europe and the United States in Suining County, and implemented the ecological birds under the forest. Three-dimensional planting of livestock, fish, undergrowth mushrooms and cash crops. Newly planted and cultivated 12,000 acres under the forest, the economic benefit of poplar trees per mu increased by 10% to 15%. With a net increase of 200 yuan per mu of forest land, the farmers have noticeably increased their efficiency and income. It promoted the breeding and promotion of new breeds of European and American poplars by neighboring farmers and implemented a highly effective three-dimensional cultivation technique. The demonstration and radiation effects were significant.


Technical Highlights Forest land is deep-turned 25 to 30 centimeters in autumn, 5 cubic meters of landfilled fertilizer per acre, 25 kilograms of urea, and the control point is 80 centimeters, 80 centimeters, and 100 centimeters in size. Afforestation uses two stalks of strong seedlings, with a density of 6 meters. 8 meters or 5 meters 10 meters. Each year in early June and early July, fertilize 1 time, each time 150 ~ 250 grams of compound fertilizer applied, pay attention to watering after fertilization. 1 to 4 years old young forests can be used as intercropping and inter-planting wheat, peanuts, soybeans, rape and other low stalk crops; middle-age forests, near-mature forests, mature forests can adopt forest husbandry or mushroom cultivation, pigs under the forest, Chickens, ducks, etc.

Market Prospects and Benefits Analysis Forest farmers (pastoral) compound management, generally 300 kg of soybean per mu, 400 kg of wheat, annual indirect economic income per mu of up to 2800 yuan, 2.5 mu of wood per mu, annual direct economic income of 1,500 yuan per mu The annual comprehensive profit per mu is over 4,300 yuan. Under the forest, there are 10 pigs, 20 slaughters per year, 200 chickens (duck), an annual indirect income of 3,600 yuan per mu, 2.75 cubic meters of wood per year, and direct economic benefits of 1,700 yuan per mu, and the annual net profit per mu. More than 5300 yuan per mu.

Single Packed Mottled Waxy Corn

Waxy corn comes in a variety of colours. Some people wonder if waxy corn is a genetically modified product. In fact, it is not. Waxy corn originated in China. It is caused by a genetic mutation. Artificial selection gradually led to the emergence of a type of tannin.

Waxy corn, also known as waxy corn, is sticky corn. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dented corn. Its chemical and physical characteristics are controlled by a recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.

Coloured glutinous corn is generally white, yellow, red, purple and black, with white, yellow and purple corn being the basic colours. Purple and white hybrids naturally become purple if the purple gene "beats" the white gene and vice versa, so if the two tie we see white and purple corn. Purple can turn into red and black corn, or as we often say, "red is purple and black is purple". Of these colourful corn, the most common yellow waxy corn is the most nutritious as it is rich in carotenoids...

Currently, the only genetically modified foods sold on the Chinese market are soybean oil and papaya. Waxy maize is a hybrid variety and is not associated with genetic modification. Therefore, it can be concluded that glutinous maize is a hybrid variety and has nothing to do with genetic modification.

Genetic modification is a type of "genetic engineering" in modern science and technology, which makes use of modern molecular biology techniques. Hybridisation is the mating of individuals of different genotypes to produce offspring that are different from the original "pure" breed. In a sense, it belongs to the natural exchange of genes that can occur in nature.
