Embodiment 1
[0027] Follow the steps below
[0028] 1. Seedling raising: In March, open a 5cm deep shallow ditch on the well-arranged seedling surface, the distance between the ditch (row spacing) is 20cm, and sow Jatropha curcas and caper seeds on demand at a plant spacing of 10cm and 5cm respectively, and cover the soil to the surface Flattened, watered thoroughly, and managed for 3 months for seedling transplantation.
[0029] 2. Preparation for interplanting: Open a 50cm-wide strip-shaped flat along the contour line of the planting plot, and the distance between the centers of the strips (row spacing) is 300cm. Leave 10cm of loose soil at the bottom; dig two 20×20×20cm caper planting ponds between the Jatropha curcas plants at a spacing of 50cm, and leave 5cm of loose soil at the bottom of the ponds.
[0030] 3. Interplanting: Jatropha curcas is planted in a pond of 40×40×40cm, caper is planted in a pond of 20×20×20cm: arrange the planting depth according to the size of the seedlings,...
Embodiment 2 and Embodiment 3
[0038] Embodiment 2 and embodiment 3: except that high-efficiency compound fertilizer: the amount of superphosphate fertilizer applied to the base fertilizer and the amount of topdressing fertilizer are different, all the other operating methods are the same as in embodiment 1, and will not be repeated. See Table 1 for the differences.
[0039] Table 1 Embodiment 1, embodiment 2 and embodiment 3 operation difference and its effect
[0040]
[0041] Note: [1] The ratio of high-efficiency compound fertilizer: superphosphate fertilizer in the basal fertilizer of Jatropha curcas and capers is the same,
[0042] [2] The ratio of high-efficiency compound fertilizer: superphosphate fertilizer in the topdressing of Jatropha curcas and capers
[0043] According to the above examples, the caper grows for 2 years and is harvested. By measuring the yield, the average harvested seed per mu is 287.3kg, and the economic income is increased by 581 yuan.
