Method for interplanting pinellia ternata and corns with mulching film covering

Abstract

The invention discloses a method for interplanting pinellia ternata and corns through mulching film covering. The method comprises steps of interplanting field preparation, mulching film covering, interplanting, management and protection, and harvesting. An interplanting land is made into a soil moisture surface with the width of 1.2 meters; a weed pressing film with the width of 1.5-1.6 m coversthe interplanting land, holes with the diameter of 3-4 cm and the row spacing of 10 cm* 15 cm are formed in mulching films; in early April, planting holes with the diameter of 5-8 cm are formed in themulching films of the soil moisture surface according to the row spacing of 60 cm* 60 cm, and 2-3 grains of corn are sown in each hole; pinellia ternata stems are sown into planting holes at the endof April when the emergence heights of corns are about 10 cm, and soil covers the pinellia ternata stems for 3-5 cm; topdressing and weeding are carried once separately when the corn grows to 50-60 cmand heading, wherein the application amount per mu is 10-15 kg; and corn and pinellia ternata products are harvested in early August and autumn, respectively. According to the invention, two plants with different classification disciplines and different heights are planted together, so that the diversity of biological species can be improved, diseases and insect pests can be effectively prevented, the use of pesticides is greatly reduced, the land utilization rate is improved, and the economic income per unit area is greatly increased.

Description

technical field [0001] The invention relates to the technical field of planting forest crops, in particular to a method for interplanting pinellia and corn. Background technique [0002] Corn is an annual herbaceous plant of the Poaceae Zea genus. It is the main grain product widely planted in various regions of my country. The planting time is generally April in spring and harvesting begins in August. However, large-scale corn planting is prone to pests and diseases, leading to excessive use of pesticides, which not only increases production costs, but also inevitably contains pesticide residues in the harvested corn, which is not conducive to people's health. [0003] Pinellia ternate (Thunb.) Breit is a perennial herbaceous plant of Araceae. The tuber is used as medicine. It is a commonly used traditional Chinese medicine. Epigastric swelling, syphilis qi syndrome; raw and external treatment of carbuncle, swollen phlegm and cough; widely used in traditional Chinese medic...

Problems solved by technology

[0004] At present, in the remote hillside areas of Yunnan, my country, there are a small amount of wild distribution of pinellia, which is far from meeting the market demand, so artificial planting of pinellia is gradually emerging

However, the existing artificial planting methods all adopt the large-area planting method of a single species.

Because pinellia likes a warm and humid environment, it is suitable for planting on small flats in mountainous, gentle slope areas with high altitude, loose, fertile, humid, and low sunlight. Therefore, for simple pinellia planting, one needs to set up a scaffold and use a sunshade net Shade, the second is overgrown with weeds, high labor cost and low benefit
