Problems solved by technology

However, sloping farmland has weak water storage and poor water retention, and the soil is very easy to lose moisture. The next light rain will dry out in the sun, and the seedlings will not be preserved in spring, and the yield will not be guaranteed in autumn. The drought resistance is poor, which seriously affects the ramie yield of sloping farmland.
[0003] In the patent 201310747975.6 (Pearl guava dry sloping land ridge cultivation method) discloses a method for cultivating guava by building contour striped slopes and changing ladders on dry slopes. The original state of the slope is greatly changed, which is likely to cause ecological hazards

Embodiment 1

[0027] Such as figure 1 with figure 2 As shown, ramie is planted in rows on the sloping farmland. The rows of ramie are basically distributed along the contour line. The distance between the rows is 600 mm. Holes are set between the rows of ramie. The width of the water storage belt is about 1000mm and the depth is about 500mm, and the water storage belt is filled with humus with high water absorption rate. Using this method to cultivate ramie on sloping farmland, it can accumulate about 0.15m3 per square meter at most when there is sufficient rainfall. 3 Even if the sloping farmland is dry and rainless, ramie still grows well and can produce stable and high yields.

Embodiment 2

[0029] As described in Example 1, however, holes with a size of 200mm, a depth of 250mm, and a spacing of 600mm are used. Since the holes are far apart, in order to effectively collect rainwater, the bottom of the hole is used to dig out the diversion diagonally upwards. Inclined ditch, so that rainwater collects into the hole along the inclined ditch (such as image 3 shown). Using this method to cultivate ramie on sloping farmland, it can accumulate about 0.15m3 per square meter at most when there is sufficient rainfall. 3 Even if the sloping farmland is dry and rainless, ramie still grows well and can produce stable and high yields.

Embodiment 3

[0031] As described in Example 1, but when the ramie is cultivated, the water-retaining agent and the fertilizer are mixed with the soil and backfilled into the holes, and the weight ratio of the water-retaining agent to the soil is 2-3‰. This is to use the characteristics of water and fertilizer and callus growth of the root system of ramie plants to promote the development of the root system around the hole and form a water and fertilizer supply and transportation center with a large root hair density, which is conducive to long-term performance of the water-retaining agent and fertilizer. Using this method to cultivate ramie on sloping farmland, it can accumulate about 0.15m3 per square meter at most when there is sufficient rainfall. 3 rainwater, saving 600m of irrigation water per mu per year 3 and can realize stable and high yield of ramie, improve fiber quality, increase ramie plant height by 27%, stem diameter by 22%, and increase yield by 25%.

Abstract

The invention relates to the field of crop cultivation, in particular to a slope cropland ramie cultivation method. The method is technically characterized in that ramie is cultivated on slope cropland in lines, and holes and humus water storage belts are distributed between the lines. When the method is adopted for cultivating ramie on the slope cropland, the slope cropland does not need to be transformed a lot, soil-stone work amount is low, no large-area bare soil surface exists on the slope cropland, natural rainwater can be fully stored and utilized, and water and soil loss can be prevented. Furthermore, compared with traditional cultivation technologies, the method has the advantages that time, labor and water are saved, and high and stable yield of ramie cultivated on the slope cropland can be realized.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for cultivating ramie in sloping fields. Background technique [0002] Ramie is a traditional economic crop in my country. It has a long planting history in China. Studies have shown that ramie is not only used for textiles, but also a good feed crop. In recent years, the planting area of ​​cultivated land on southern slopes in my country has increased year by year. However, sloping farmland has weak water storage and poor water retention, and the soil is very easy to lose moisture. The next light rain will dry out in the sun, and the seedlings will not be preserved in spring, and the yield will not be guaranteed in autumn. The ability to resist drought is poor, which seriously affects the ramie yield of sloping farmland. [0003] In the patent 201310747975.6 (Pearl guava dry sloping land ridge cultivation method) discloses a method for cultivating guava by constructing c...
