What influence does the latitude position of our country have on our climate and agriculture?

From the latitude position: 4° N ~ 53° N, north-south latitude 49, the natural landscape of Bloom is rich and comprehensive, with ice and snow in Heilongjiang and warm spring in Hainan Island.

From the latitude position, the latitude across the north and south is very wide, most of them are located in the middle latitude area, belonging to the north temperate zone, and a few areas in the south belong to the tropical zone without cold.

The land is located between 20 degrees and 45 degrees north latitude, with a large temperate area. Adequate sunshine is beneficial to the growth of crops.

Most parts of China belong to subtropical monsoon climate and temperate monsoon climate, and the climate is mild and humid, which is conducive to crop growth and human survival.

For agriculture: the cultivated land is widely distributed, which is suitable for the growth of various crops and forms the overall structure of "rice in the south and wheat in the north". At the same time, crops such as corn and potatoes are also widely distributed.

For animal husbandry:

There are three kinds of animal husbandry, the specific analysis is as follows:

Animal husbandry in agricultural areas

Animal husbandry in agricultural areas is called animal husbandry in agricultural areas.

The characteristics of animal husbandry in agricultural areas are as follows: ① Mainly grain-consuming animal husbandry. The main types of livestock are pigs, poultry, farm animals, livestock and goats. Feed sources are agricultural products, feed grains, straws, weeds, wild vegetables and so on. Grazing is carried out on hillsides and scattered grasslands. ② Dual-purpose animal husbandry is relatively developed, such as raising cattle, horses and donkeys. ③ Feeding mainly in house. Except for short-term stubble grazing after harvest, the rest of the time is artificially raised in the barn. ④ Feed expenses account for a relatively high proportion, generally accounting for more than 65% of the animal husbandry expenses. It can completely realize the combination of agriculture and animal husbandry, with meticulous management and high production level. The mode of operation is mainly farm sideline, as well as state-owned pastures and professional households. At present, rural animal husbandry is still the main body of animal husbandry in China.

Pastoral animal husbandry

In grassland and desert areas, animal husbandry based on grazing is called pastoral animal husbandry. Livestock are mainly herbivores. Extensive management, poor combination of agriculture and animal husbandry, seasonal fluctuation of forage supply, vulnerability to severe weather threats, and low and uneven livestock productivity. Pastoral areas in China are located in the northern and western frontiers, including Inner Mongolia, Xinjiang, Tibet, Qinghai, Sichuan, Gansu, Ningxia, Heilongjiang, Jilin, Liaoning, Hebei, Shanxi and other provinces. * * * There are 266 counties (banners) in pastoral, semi-agricultural and semi-pastoral areas, accounting for more than 50% of the country's total land area, and the number of grazing livestock accounts for 22% of the country's total livestock. The basic principles of development are: rational utilization and protection of existing natural grassland; Focus on grassland construction and other construction, such as developing water sources, storing grass and preparing materials, and improving the production conditions of animal husbandry; Adjust the herd structure and develop seasonal production, such as slaughtering lambs in the same year and fattening and slaughtering beef cattle in the early stage to enrich the summer and autumn seasons and avoid the shortage in winter and spring; Combination of agriculture, forestry and animal husbandry; Adopt applicable technology and speed up technological transformation.

Grassland animal husbandry

The animal husbandry that uses grassland to graze livestock directly, or mows grassland as forage to raise livestock is animal husbandry 4 grassland animal husbandry. Grassland in China can be divided into natural grassland, artificial grassland and semi-artificial grassland according to the nature of plant community. According to the distribution of grassland, it can be divided into two types: northern grassland and southern grassland. The problems of grassland animal husbandry in China are the degradation of grassland resources and the low level of animal husbandry productivity. In addition to the lack of advanced management methods, it is also related to the poor natural conditions in these areas.

The main ways to develop grassland animal husbandry are: ① improving grassland. (2) Expand artificial grass planting where conditions permit. (3) build a barn. ④ Strengthening the construction of service system. ⑤ Reform the unreasonable circulation system.
