At present, the planting area of the dragon fruits is gradually enlarged, most of the dragon fruits are in a single cultivation mode, and land resources and light energy cannot be fully utilized.
Disclosure of Invention
The invention aims to provide a planting method for interplanting pitaya and red fruit ginseng, and solves the technical problem that land resources and light cannot be fully utilized in the existing single pitaya cultivation mode.
By scientifically setting the row spacing, the plant spacing and the three-dimensional space between the red fruit and the dragon fruit, matching with measures such as reasonable interplanting cultivation technology and the like, the land and the light energy are reasonably utilized, so that the land resource is utilized to the maximum, the growth of weeds is inhibited, the water and soil loss is reduced, the utilization rate of the fertilizer is improved, the ecological environment is improved, the soil fertility is improved, the management and the protection are convenient, the production cost is reduced, the yield per unit area is effectively improved, and the economic benefit is improved.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a planting method for interplanting pitaya and red fruit ginseng comprises the following steps,
step 1: preparing soil, namely stirring the soil by using 2.0 percent of nematicide root-knot-dispersing slow-application particles and ridging;
step 2: erecting dragon fruit brackets, planting dragon fruits on the side edges of the brackets, and planting red fruit ginseng between the brackets;
and 3, step 3: the pitaya is grown robustly and mature branches without diseases and insect pests, the pitaya ginseng is grown robustly and seedlings without diseases and insect pests, the pitaya is planted by adopting an A-shaped pitaya frame building cultivation and column type cultivation method, and the pitaya ginseng is planted between two stand columns;
and 4, step 4: fertilizing management, and managing flowering phase and fruit development phase;
and 5: performing field management, namely pruning and pinching branches and leaves during the planting period of the dragon fruits;
step 6: harvesting the fruits, wherein the flowering period of the pitaya is from 4 months to 11 months, and the fruits are harvested after 35 to 45 days of flowering; the fruit of the red ginseng can be harvested when the fruit turns color to more than 80% in the mature period of 12 months to 3 months of the next year.
Furthermore, in the ridging operation in the step 1, the height of the ridge is 20-30 cm, the width of the ridge is 100-120 cm, and the distance between the ridges is 100cm.
Furthermore, the specific process of the step 2 is that an A-shaped bracket structure is set up, the space between the A-shaped brackets is set up according to 2m-2.5 m, the top ends and the side surfaces of the brackets are connected together by steel wire ropes, a column structure is set up, the dragon fruits are planted at the columns of the ridges, the columns are set up according to the plant spacing of 1.5-2.0, and a circular steel ring bracket is set up at the top ends of the columns; the red fruit ginseng is planted between the two columns of the dragon fruit, and the planting distance of the red fruit ginseng on the ridge is 50-100 cm.
Further, the concrete process of the step 3 is that the A-shaped frame is arranged in the center of a ridge according to the direction of the ridge, the dragon fruit seedlings are planted on a single plant at a plant spacing of 50-80cm, the dragon fruit plants grow upwards along the supporting bamboo strips, 800-1200 dragon fruits can be planted per mu, and 1 red ginseng is planted between two dragon fruits; the upright post is arranged in the center of the ridge, 3-4 dragon fruit seedlings are planted around the upright post, the dragon fruit plants grow upwards along the upright post, and 560-600 dragon fruits can be planted in each mu; the method comprises the following steps that 2-3 red fruit ginsengs are planted between the red fruit ginsengs and two stand columns, old dragon fruit orchards are directly planted under dragon fruit plants on ridges without shading, the dragon fruit is planted in 3-9 months, the red fruit ginsengs are planted for 3-5 months, however, a dragon fruit planting support must be built first, then the dragon fruit and the red fruit ginsengs are planted, the newly planted red fruit ginsengs need shading, shading nets with 65-75% light transmittance are adopted for shading, and black weed suppression films cover empty spaces between the two ridges.
Further, the step 1 also comprises the steps of applying base fertilizer, applying enough organic fertilizer during soil plowing and soil preparation, covering soil after applying the fertilizer, and using 2000kg-3000kg of organic fertilizer and 100kg-150kg of compound fertilizer for each mu of pitaya and red ginseng to share the base fertilizer.
