Is Handan suitable for planting ugly oranges?

Handan is not suitable for planting ugly oranges (I don't know the fire). It is cold in winter, and ugly oranges are not cold-resistant and easy to freeze to death.

Analysis and explanation:

It is required that the soil layer is deep (60㎝) and fertile; The ph value of the soil is 5.5-7.0; The slope of the orchard is less than 25 degrees.

It is best to sit on the slope facing south with deep and fertile soil below 400 meters above sea level.

The growth, flowering and fruiting of citrus trees are closely related to temperature, sunshine, moisture (humidity), soil, wind, altitude, topography, slope direction and other environmental conditions, among which the temperature has the greatest influence.

Even if the temperature difference is 0.5℃, sometimes there will be completely different results.

The growth and development of citrus fruits need a temperature of 65438 02.5 ~ 37℃.

The day and night temperatures of flower bud differentiation in autumn are about 20℃ and 65438 00℃, respectively, and the soil temperature of root growth is roughly the same as the ground temperature.

It is also planted in Dan Ling, Neijiang, Jintang, Chongqing, Yunnan, Jiangxi, Hunan and Zhejiang.

Too low a temperature (-5℃) will freeze oranges.

Handan is a typical warm temperate semi-humid continental monsoon climate, with abundant sunshine, simultaneous rain and heat, and dry and cold seasons. The four seasons alternate obviously, showing the characteristics of drought and little rain in spring, hot and rainy in summer, mild and cool in autumn and cold and dry in winter.

Annual average temperature 14℃, maximum Leng Yue (1 month) -2.5℃, extreme minimum temperature -20℃, hottest month (July) 27℃, extreme maximum temperature 42.5℃, frost-free period 200 days, annual sunshine 2557 hours.

So this area is not suitable for growing ugly oranges.

Training points:

It is required that the soil layer is deep (60㎝) and fertile; The ph value of the soil is 5.5-7.0; The slope of the orchard is less than 25 degrees. When planning a garden, there should be necessary roads, irrigation and drainage, water storage and ancillary building facilities.

In terms of specific planning, we should concentrate on one place as much as possible and build gardens in places with good traffic and water conditions. Time: Generally, it is planted in September-165438+10 after the autumn bamboo shoots mature or before the spring bamboo shoots germinate in February-March.

Density: Plant spacing is 3m× row spacing is 4m, and 55-60 plants are planted per mu. Planting technology: digging planting holes with soil: pulling wires at certain intervals, digging planting holes with a depth of 80cm and a width of 80 cm, then pressing green manure with a depth of 50cm and backfilling soil with a height of 40cm for planting; Ridge planting: 8 meters, 60-80㎝ wide and 40-60cm deep, with 2 ridges per grid (width 1.5m, center distance 4m, height 20-30cm).

When planting, the roots of seedlings should be trimmed appropriately, placed in the center of the planting hole, stretched and righted, and the seedlings should be gently lifted upward while filling the soil, so that the roots are closely connected with the soil.

Water the roots, make a 1m tree tray around the seedlings, and cover it with chaff.
