territorial scope

Tangxing production area in Tianzhen County is located in Pingchuan District, west of Tianzhen County, 6 kilometers southwest of the county seat, in the whole town of Nanhebao, which is dominated by Dongshahe Village. Its geographical location is11402'12 "-11402' 53" north latitude.

Natural ecological environment and human and historical factors

(1) Soil landform: The soil type of origin is middle-earth cultivated and irrigated by chestnut cinnamon soil, with moderate texture, deep soil layer and fertile soil. According to soil analysis, the organic matter in cultivated soil is between 0.8- 1. 1%, the nitrogen content is 0.06-0.08%, the available phosphorus 15-20ppm, and the available potassium is 85- 123ppm, so farmers have a high level of fertilization. According to the survey, the average annual application of organic fertilizer is 3000 mu.

Tianzhen Tangxing is located in the east of Tian Yang Basin, on the second terrace on the south bank of Nanyang River, with Ma 'anshan in the north, Gu Feng in the south and hilly areas in the east, which forms the topographic characteristics of high in the north and low in the east, and has a unique geographical environment for the production of Tangxing. Moreover, the land of origin is flat, the soil layer is deep, the soil is fertile, and the underground water source is rich, so it is an ideal place to produce Tangxing.

(2) Hydrological situation: The village is located in the middle and lower reaches of Jifengyao alluvial fan and Sansha ancient river area, and belongs to the weak and medium-rich alluvial plain in loose rock pore water area of Pingchuan District. Within the depth range of 0- 100 m, the water-bearing lithology in the south of the village is mainly gravel with a thickness of 60-70 m, and in the north of the village,

Coarse sand is dominant, and the aquifer is 50-60m thick. Within the depth range of100-200m, the aquifer is 40-50m thick and the lithology is mainly coarse gravel. Within the depth of 200-300m, the aquifer is 35-40m thick and the lithology is mainly coarse sand. According to the 24m-80m deep hole, the buried depth of water level is generally 6- 12m, and the shallowest is 3m. The main lithology of aquifer is fine sand, medium fine sand, medium coarse sand and coarse sand. After years of underground water exploitation in New China, the average water level has dropped by 5.5- 15.5 meters, the annual runoff of Sansha River is 9.49 million cubic meters, the flood is 500,000 cubic meters, and the annual sand mining volume is 2 million tons. There is salt water between 0-15m locally.

(3) Climate: The climate of the producing area belongs to semi-arid temperate continental monsoon climate, and it is controlled by southeast airflow in summer, with southeast wind, hot and rainy; Winter is controlled by the northwest climate, and the west is northerly, with cold and little snow. The annual average temperature is 6.5℃, the highest in July is 265,438 0.5℃, and the lowest in 1 month is-65,438 0.2℃. Annual active accumulated temperature is 2829℃, frost-free period 125. The climate is characterized by rain and heat, and the temperature difference between day and night is large (10- 15℃), which is very beneficial to the growth and sugar accumulation of Tang Xing.

(4) Human history: Dongshahe village has the habit of planting fruit trees. As early as the late Qing Dynasty and the early Republic of China, Penang, Shaguo, Apricot, Plum, Grape and other trees were planted. Tangxing was introduced and planted sporadically in the early 1980s, mainly in courtyards. By the end of last century, large-scale planting began. By 2007, it had grown to 1 1,000 mu, becoming a well-known planting area of Tangxing in northern Shaanxi.

Production technical requirements

(1) Selection of producing area and special content: Tangxing is planted in a place with abundant sunshine, deep soil layer, fertile soil and convenient irrigation and drainage, so the gardens in the surrounding hilly areas are built in the direction of leeward and sunny, avoiding the concave places and valleys of tuyeres and hillsides to avoid the harm of late frost at flowering, and the gardens in Pingchuan area are built in loam farmland with convenient irrigation and drainage. At the same time, the air in the producing area is fresh, and irrigation water and soil are not polluted. There is no pollution from industrial and mining enterprises within 10 km around Tangxing production area, far away from the pollution of "three wastes" and hospitals and living quarters, and there has never been a landfill of "three wastes" in history.

(2) Variety selection: Tianzhen Tangxing is a variety with single fruit weight 150- 170g, round fruit shape, yellow fruit surface, hard, crisp and smooth taste, thick pulp, strong taste and sweet taste, which is suitable for local cultivation.

(3) Production process management: Tianzhen is located in a cold area with few pests and diseases. According to the forecast of the county center forecasting station and the occurrence of local diseases and insect pests over the years, advanced and practical technologies are applied.

Combined with the local people's accumulated experience in soil control, control the occurrence and spread of pests and diseases, so as to give priority to prevention, combine prevention with control, comprehensively control, suit the remedy to the case, apply drugs in a timely and appropriate manner, vigorously promote agricultural control, biological control, physical control, facility protection and biochemical control, do a good job in rural sanitation, be familiar with the types of pests and diseases, understand the nature of pesticides, improve the technical level of application, and publicize scientific fertilization and scientific irrigation and drainage. Know the weather forecast information in time to prevent freezing injury at flowering stage. Fertilization is mainly based on base fertilizer and organic fertilizer, and the application technology of foliar topdressing is popularized.
