How to plant mulberry trees on steep slope farmland and hilly terraces? What kind of choice is good?

Different geographical terrain environment in planting mulberry precautions and variety selection will be different, then how to plant mulberry in steep slope farmland, hilly terrace? What kind of choice is good?

If mulberry trees are planted on a steep slope, we can adopt three planting patterns.

mode 1

Mulberry orchard intercropping on steep slope horizontal terrace

The model aims to make full use of cultivated land resources, combine with basic farmland construction projects, expand mulberry garden area, maximize land production potential, and effectively control soil erosion on steep slope cultivated land. Mulberry leaf yield per 667m2 reached more than 1000 kg, total income of sericulture and intercropping crops reached more than 800 yuan.

① Suitable area: steep slope with slope of 25-30 degrees, deep soil layer and good soil quality.

(2) Variety selection: Husang 32, Lusang, Nongsang series.

(3) Form of garden construction: first, build horizontal terraces with width of 2-3m according to contour lines, and then plant mulberry trees along the terraces with plant spacing of 0.8- 1.0 m.

4. Form of intercropping: potato crops, bean crops, vegetables, peanuts, etc. can be planted in the terrace.

5 Cultivation form: conventional cultivation in the middle of terrace, weeding and fertilization in mulberry rhizosphere.

6. Cutting form: winter and spring cutting form is adopted to form middle and low stem tree type.

7. Cultivation management: formula fertilization, increased application of nitrogen fertilizer and organic fertilizer.

Mode 2

Ecological mulberry garden with steep slope contour line, wide row and dense plant

Objective of model: control soil erosion and enlarge mulberry planting area. Make silkworm industry and zoology environment construction develop synchronously. Mulberry leaf yield per 667m2 reached more than 1200 kg, total income of sericulture and intercropping crops reached more than 800 yuan.

① Suitable area: steep slope with slope of 30-35 degrees, deep soil layer, good soil quality and good illumination.

(2) Variety selection: Husang 32, Lusang, Nongsang series.

(3) Form of garden construction: planting mulberry trees with wide rows and dense plants along contour lines. Row spacing 2.0-2.5m, plant spacing 0.5-0.8m.

4. Form of interplanting: planting daylily among mulberry trees.

5 Cultivation form: mulberry field only weeding, fertilization, no-tillage. 3-4 Years later, mulberry and daylily can form a retaining fence.

6. Cutting form: winter and spring cutting form is adopted to form middle and low stem tree type.

(7) Cultivation management: formula fertilization, increased application of phosphorus and potassium fertilizer.

mode 3

Ecological mulberry garden on steep slope horizontal stone ridge terrace

The model aims to make full use of cultivated land resources, construct basic farmland, expand mulberry planting area, maximize land productivity potential, and effectively control soil erosion on steep slope farmland. Mulberry leaf yield per 667m2 reached more than 600 kg, total income of sericulture and intercropping crops reached more than 500 yuan.

① Suitable area: slope at 25-40 degrees, steep slope in rocky mountain area.

(2) Variety selection: Husang 32, Nongsang 14, 792.

(3) Form of garden construction: build horizontal stone terraces according to contour lines, with terraces spaced 3-4m apart, plant mulberry trees at the thicker soil layer outside terraces, with plant spacing of 0.8- 1.0 m.

4. Form of intercropping: Eulaliopsis binata or daylily can be planted on the edge of stone ridge, and beans, traditional Chinese medicine or other crops can be intercropped on wider terraces.

(5) Cultivation form: conventional cultivation between terraces, fertilization and weeding in mulberry rhizosphere. Pay attention to cultivating soil to the edge of the stone ridge, and finally form a certain reverse slope angle to prevent rain leakage and cause stone ridge landslide.

④ Management form: winter and spring cutting form pruning, forming a medium stem tree type.

7. Application and management: formula fertilization, increased application of nitrogen fertilizer, organic fertilizer and micro-fertilizer.

If terraces are in the hills, we can adopt the planting mode of mulberry ecological forest with ground stalks, as follows:

Model objectives: greening and protecting terraced fields, preventing soil erosion, improving ecological environment, accelerating mulberry leaf transformation and utilization, increasing farmers 'economic income.

① Suitable area: terraced fields in hilly areas.

② Variety selection: Grusan series

(3) Form of garden construction: plant spacing of 2-2.5 meters, single row planting on the ridge.

④ Management form: pruning by the method of cutting out, forming a tree type with medium and high stems.
