Pecan and peony intercropping method

Abstract

The invention discloses a pecan and peony intercropping method. Pecan and peony intercropping is realized by planting pecan on a wide ridge plane and arranging peony planting belts on two sides. By the pecan and peony intercropping method, the problem of low land utilization rate of pecan plantations can be improved, and cost saving is realized; in addition, by understorey intercropping of peony, understorey soil conditions can be improved, and soil water retention capacity is improved. Since the pecan is a deep-rooting plant while the peony is available for surface planting, soil nutrients can be used completely, and the problem of long production time of pecan can be solved by benefits generated by fruits of oil peony to obtain economic benefits in the short term.

Description

technical field [0001] The invention relates to the field of agriculture and forestry planting, in particular to a method for intercropping pecans and peonies. Background technique [0002] American hickory (Carya illinoinensis Koch), also known as thin-shell hickory and long hickory, belongs to the genus Hickory of Juglandaceae. It is an ecological and economical tree species integrating high-grade dried fruit, landscaping and high-grade wood. Its fruit "pecan" is a very popular high-quality dried fruit food in the market at present. However, the current domestic production is low and the demand is relatively large, mainly relying on foreign imports. Therefore, planting American pecans has a very promising prospect. [0003] American hickory has been developing slowly in the nearly 100-year history of its introduction to China. It was not until the end of the 20th century and the beginning of the 21st century that domestic research on this tree species began to flourish. At...

Problems solved by technology

However, the American hickory is a tall tree species, and the planting density is too high, which leads to the excessive canopy of the plants entering the production period, which affects the normal physiological and reproductive growth of the plants, and the fruit yield is far from the expected effect.

However, if you choose a larger row spacing for planting, the land utilization rate in the early stage will be lower and the planting cost will be higher.

In order to solve these problems, many domestic growers have begun to try intercropping with other crops, but few have achieved high yields
