Pennisetum sinese and amorphophallus bulbifer intercropping method

Abstract

The invention provides a method for intercropping pennisetum sinese and amorphophallus bulbifer, and belongs to the technical field of crop cultivation. The intercropping method comprises the following steps that ditching is carried out according to the mode that 2-3 ridges are formed at the interval of one ridge, pennisetum sinese is planted at the non-ridging positions from November to December of the previous year, film mulching is carried out on the ridges, and amorphophallus bulbifer is planted on the ridges from April to May. According to the method, a composite ecological planting mode is adopted, reasonable matching and intercropping are achieved, the land utilization rate can be increased, the biological diversity can be increased, and the unit area output of the young rubber garden can be increased with low investment and high benefits; aiming at the growth characteristics of two crops (shade-loving moisture-proof amorphophallus bulbifer and sun-loving long-period high-stalk pennisetum sinese), the two crops can compensate each other and take respective needs in time and space, the advantages and characteristics of hot area resources are fully played, and the green sustainable development of the rubber tree planting industry is comprehensively promoted.

Description

technical field

[0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for intercropping giant fungus grass and konjac bulbils. Background technique

[0002] The traditional rubber plantation mode is based on rubber trees as the single dominant tree species, with low land utilization rate, large labor input, serious soil erosion, single product output, and great risk of economic benefits being affected by the market. By developing economic crops under rubber gardens, improving the land utilization rate of rubber gardens, increasing the biodiversity of rubber gardens, increasing the output per unit area, improving the ecological functions of rubber gardens, maintaining the confidence of rubber farmers in production, and enhancing production enthusiasm. The Amorphophallus konjac species, native to the southwestern border of my country and the adjacent South and Southeast Asian countries, has the advantages of strong disea...

Embodiment 1

[0033] (1) material selection: select the underground bulb of bulbil yellow konjac as propagation material;

[0034] (2) Soil preparation: Before planting, apply 80kg of nitrogen, phosphorus and potassium compound fertilizer, 1250kg of organic fertilizer, 80kg of calcium magnesium and phosphate fertilizer, and 100kg of quicklime into the surface soil; The width is 1.1m, the width of the ridge is 0.90m, the height of the ridge is 30cm, the distance between two ridges is 30cm, and the distance between 3 ridges is 1.0m, and there is no ridge;

[0035] (3) Planting method: Set the row spacing of the yellow konjac bulbils to 50cm×60cm, and the plastic film will be punched in advance according to the row spacing of the plants. In November of the previous year, the giant fungus grass stem section containing 2 cryptocephalic buds will be intercepted, and the row spacing of the plants will be 40cm. Place it horizontally in the middle of the 1.0m reserved position without ridges, ditch ...

[0039] (1) material selection: select the bulbil of bulbil yellow konjac as propagation material;

[0040](2) Soil preparation: Before planting, apply 60 kg of nitrogen, phosphorus and potassium compound fertilizer, 1000 kg of organic fertilizer, 60 kg of calcium magnesium phosphate fertilizer, and 75 kg of quicklime, and turn it into the topsoil; The width is 1.0m, the width of the ridge is 0.8m, the height of the ridge is 20cm, the distance between the two ridges is 20cm, and the distance between the two ridges is 0.8m, and there is no ridge;

[0041] (3) Planting method: set the row spacing of the yellow konjac bulbils to 30cm×30cm, and the plastic film will be punched in advance according to the row spacing of the plants. Place it vertically in the middle of the reserved position of 0.8m without ridge, and plant it with 10cm ditch, then cover the soil and compact it, and pour enough water to fix the roots; in May, cover the perforated mulch on the completed ridge, and plan...
