Doing a good job of what specialty agriculture

Doing a good job of saline and alkaline land specialty agriculture.

In Cangzhou, the dry alkaline land in the mouth of the local people is known as saline alkaline land. People familiar with agriculture and rural areas may recall the white layer of salt that rises from the saline land in the fall. Saline land means crops are difficult to grow.

Development of agricultural characteristics, we must focus on the local conditions, so that the saline and alkaline land can also be "turned into treasure". During the visit, the key role of scientific and technological innovation was emphasized to increase the renovation and upgrading of saline and alkaline land, strengthen the development and promotion of crop varieties suitable for saline and alkaline land, and effectively expand the sowing area of suitable crops.

This, the seed is important. Pointed out the importance of planting a good choice of seeds: "Farmers say, 'a good son to a good mother, a good seed more grain', 'planting does not choose the seed, exhaustion fall empty'." In the dry and alkaline wheat fields, inspecting the wheat, there are small Yan 60, Cangmai 6002, Jiemai 19 and other drought-resistant saline varieties. This is precisely the local agricultural personnel around the "seed, fertilizer, sowing, tube" and other key aspects of the implementation of the 30 national and industry technical standards, cultivated varieties suitable for planting.

While the dry alkaline soil salinization degree is high, but the special planting conditions created a dry alkaline wheat unique quality - potassium, calcium, magnesium, iron and zinc content is high, the protein content is as high as 13% to 16%, processed out of the flour wheat aroma, soft and glutenous, very suitable for the production of buns, noodles and other traditional handmade noodle dishes.

Causes of soil salinization

Soil salinization is mainly determined by nature, when the water table rises or the rainy season water level is large, the probability of soil salinization will increase, and secondly, some relatively closed terrain, due to the salt can not be drained out of the soil, but also aggravate soil salinization.

Soil salinization is a process in which salts from the soil substrate or groundwater rise to the surface with capillary water, and water evaporates so that salts accumulate in the surface soil. It is the phenomenon or process of accumulation of soluble salts in the surface layer of soil, also known as salinization.

China's saline soil or saline-alkaline soil has a wide distribution range, large area and many types, with a total area of about 100 million hectares. It mainly occurs in arid, semi-arid and semi-humid areas. The soluble salts of saline soils mainly include sulfates, chlorides, carbonates and bicarbonates of sodium, potassium, calcium and magnesium. Sulfates and chlorides are generally neutral salts, and carbonates and bicarbonates are alkaline salts.

China is also a widely distributed saline soil country, compiling China's saline soil distribution map rough calculation, China's saline soil area of about 100 million ha, of which the modern saline soil accounted for about 37%, residual saline soil accounted for about 45%, the potential saline soil accounted for about 18%. China's saline soils are distributed in 19 provinces and regions, including Liao, Ji, Hei, Ji, Lu, Yu, Jin, Xin, Shaanxi, Gan, Ning, Qing, Suzhou, Zhejiang, Anhui, Fujian, Guangdong, Inner Mongolia and Tibet.
