The pinyin pronunciation of straw is jiē

as follows:

Straw is a general term for the stem and leafy (spike) portion of a mature crop. It usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseed rape, cotton, sugarcane and other crops (usually coarse grains) after the seeds are harvested. More than half of the products of crop photosynthesis are present in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, making it a renewable biological resource with multiple uses.

Straw is also a kind of roughage. Characterized by high crude fiber content (30%-40%), and contains lignin and so on. Although lignin cellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminants such as cattle and sheep. Chinese farmers have a long history of utilizing crop stalks, but only because of the low level of agricultural production and low yields in the past, the amount of stalks was small.

In addition to a small amount of straw used for gaskets, feeding livestock, and partially used for composting, most of it was burned for fuel. With the development of agricultural production, China since the 1980s, grain production has increased dramatically, the amount of straw is also more, coupled with the promotion of fuel saving and coal saving technology, the popularity of burning coal and the use of liquefied petroleum gas, so that a large number of rural areas have a surplus of straw.

At the same time, the progress of science and technology, the improvement of the level of agricultural mechanization, so that the use of straw from the original composting fertilizer into straw directly to the field. The majority of Chinese scientists and technologists have conducted fruitful research on the return of straw to the field. There are many ways to return straw to the field, such as composting, returning straw to the field, returning straw to the field directly, and so on. Crop straw for turning pressure to return to the field or cover to return to the field is an effective measure to increase production.

During the eighty-five period of the Chinese Academy of Agricultural Sciences, Southwest Agricultural University, Hubei Academy of Agricultural Sciences and other units of the straw returned to the field test results show that the implementation of straw returned to the field are generally able to increase yields by more than 10%, statistics of more than 60 national material, yield range of -4.8 to 83.4, an average yield increase of 15.7%. Adhere to the perennial straw return to the field, not only in the fertilization stage has obvious yield increase, and the after-effects are very obvious, there is a sustained role in yield increase.
