In which area of China is the yield of ginseng fruit large?

The yield of ginseng fruit is very high in Hexi Corridor of China.

The requirements of Zanthoxylum bungeanum for environmental conditions have typical desert oasis characteristics, which are very similar to the climate characteristics of Hexi Corridor in China. The highest daytime temperature in China Hexi Corridor in May can reach 22-25℃, and the ground temperature is stable at 14- 15℃, which is beneficial to seedling emergence. The growing period is from May to June, and the maximum temperature is generally between 265,438+0-28℃. The temperature is stable between 25-32℃ in July and August, which can promote flowering and fruiting. The climatic characteristics are very consistent with the growth characteristics of spiny pumpkin and suitable for its growth.

Cucurbita spinosa has strong adaptability and strict requirements on soil. Any soil that can grow cucumbers, gourds, watermelons and vegetables can be planted. In order to avoid repeated cropping, it is advisable to choose the soil where cucurbitaceae plants were not planted in the previous cropping, cultivate directly with high ridges covered with plastic film, and ridging 7- 10 days before sowing.

Pumpkins like rich soil. Before ridging, apply 45t/ha of high-quality organic fertilizer and 375-450kg/ha of diammonium phosphate compound fertilizer, harrow and grind the fertilizer until the ridge width is130cm and the ditch width is 30cm. Water after ridging, and cover with plastic film to keep warm and moisturize in time after the water falls dry. Double-row planting, plant spacing of 45 cm, can protect 27 thousand plants/hectare.

Soil climate in Hexi Corridor;

1 climate

Cold wave weather often forms in Hexi Corridor in winter and spring. The main source of summer precipitation is the summer monsoon invading this area. The climate is dry, hot and cold change dramatically, windy and sandy. From east to west, the annual precipitation is decreasing and the dryness is increasing. Climate The climate of Hexi Corridor belongs to continental arid climate. Although there is little precipitation (the annual precipitation is only about 200mm), other climatic conditions for developing agriculture are still very favorable.

The local clouds are scarce and the sunshine time is long. The annual sunshine can reach 2550 ~ 3500 hours, which is rich in light resources and is very beneficial to the growth and development of crops. Because it is located in the mid-latitude zone, and the altitude is high, the heat is insufficient, but the temperature is high in the growing season of crops, which is beneficial to the accumulation of substances in crops, especially suitable for the accumulation of sugar in fruits and vegetables.

2. Land

The cultivated land in Hexi Corridor is mainly distributed in the piedmont plain. The upper part of alluvial fan is mainly composed of gravel and coarse sand, which is rarely used. The middle and lower parts of alluvial fans are mainly sandy soil, mostly cultivated land. The alluvial plain has fine soil, mainly composed of clayey silt and loam, and is also the main area for farming. Under the condition of long-term cultivation and irrigation, a soil layer with a thickness of 1 meter, high organic matter content and high soil fertility has been formed, which provides superior conditions for developing agriculture.
