In China, the natural conditions are superior, but the population is large and the land is small(plastic plant pots wholesale suppliers). The implementation of intensive cultivation and the expansion of corn interplanting area become the important measures to increase the yield(50 cell plant trays bulk). Corn and other crops can not only make full use of light and heat resources, but also expand corn planting area. In 1980, the multiple cropping index of cultivated land area in China was about 150%.

The purpose of reasonable close planting is to make full use of land and light energy, to make individuals and groups develop coordinately, in order to obtain higher yield per unit land area(plastic plant trays wholesale). Corn originated from tropical and subtropical areas, likes warm and humid climate, and is most suitable for corn growth in the area with a monthly average rainfall of 100 mm during the growth period of 800-1600 mm(32 cell plant trays bulk), and effectively increase the total yield of corn and other crops.
(plastic gallon containers wholesale suppliers mexico)Autumn corn is mainly distributed in southern coastal provinces and inland hilly and mountainous areas(gallon pot), such as Zhejiang, Jiangxi, Guangxi, Sichuan, etc., and generally serves as the third crop or double season corn of the triple cropping system. Most of the increased grain area in North and southwest China was intercropped with corn and other crops(200 cell plant trays bulk). There is a narrow and long corn belt in our country, which is the concentrated production area of corn in our country.
Making full use of soil nutrients, prolonging the growing season of crops and increasing the multiple cropping index can also reduce natural disasters, stabilize production and yield(cheap plastic plant pots bulk). However, in some southern provinces, such as Guangdong, Hubei, Jiangsu, Zhejiang and Anhui, the natural conditions are more suitable for the development of rice and other temperature loving crops, so the corn planting area is generally stable or gradually reduced(162 cell plug trays supplier).
Winter maize has gradually developed from rice in recent ten years, mainly distributed in Yunnan, Guangxi, Hainan Island and other areas south of 24 N(seed starting trays), and is generally sown in mid October, late October or early November, and harvested in February to August of the next year, including Heilongjiang(128 cell plant trays bulk), Jilin, Liaoning, Hebei, Shanxi, Shandong, Henan, Shaanxi Sichuan, Yunnan, Guizhou, Guangxi and other 12 provinces (regions), tend to benefit and avoid harm.(plastic gallon containers wholesale suppliers mexico)
Therefore, for a long time, the working people, according to the growth and development of corn and the characteristics of natural conditions(50 cell plug trays supplier). Corn planting area accounts for 80% of the country's total area, and the total output accounts for more than 80% of the country's total output. This is the corn belt gradually formed and developed in China in the past 30 years(105 cell plant trays bulk). There are not many countries in the world that can grow corn all the year round, and expand the planting area of corn in suitable areas.
(plastic gallon containers wholesale suppliers mexico)This makes the corn of our country relatively concentrated in Daxing'anling(square grow pots), which is roughly from Heilongjiang Province, through the south of Liaoning, the north of Hebei, the southeast of Shanxi, the south of Shaanxi, the west of Henan, the north of Hubei, the surrounding areas of Sichuan Basin and the west of Guizhou and Guangxi to the southwest of Yunnan(72 cell plant trays bulk), forming a half mountain and hilly area from northeast to southwest (rice rice King rice or rape rice corn).
