How to interplant Pinellia ternata in fruit forest

Encouraged by the national preferential policy of returning farmland to forests, the production area of rural fruit trees and gardens has increased significantly in the past two or three years. At present, most fruit forests are shaded by green trees. due to the lack of light between the trees, interplanting conventional crops, such as peanuts, soybeans, rape, corn, and so on, will lead to poor growth, low yield and poor efficiency. At present, many farmers are most concerned about how to use the open space between rows of fruit forest to increase the benefit of interplanting. In practice, it is found that if the Chinese herbal medicine is interplanted in the fruit forest, the economic income can be significantly increased.

Dry Pinellia ternata is the most suitable for fruit forest interplanting, because it likes to shade the environment, and the plant is easy to fall seedlings (seedlings withered and yellow and atrophy) in the high temperature season, causing the tuber to stop growing, while the hot summer fruit forest Yemao is the natural protective umbrella for sunshade during the vigorous growth period of Pinellia ternata, which provides favorable conditions for the normal growth of tubers.

The fruit forests suitable for interplanting in Pinellia ternata are Evodia, Fructus Aurantii, Gardenia jasminoides, Magnolia officinalis, Eucommia, Phellodendron, Magnolia, Ginkgo biloba and other woody medicinal materials, as well as citrus, navel orange, peach, pear, jujube, apple, grape and other fruit trees. In general, about 120 kg of dry products can be harvested in interplanting Pinellia ternata per mu of fruit forest. according to the current market price, the planting benefit can be increased by 3 to 5 times compared with interplanting conventional crops. The main points of cultivation are as follows:

Sowing in spring can be sown from March to May. Ploughing the land once before sowing, pay attention to keep a certain distance from the trees during ploughing, do not hurt their roots, and combine ploughing with 3000 kg of mature organic fertilizer (or 100kg of phosphate fertilizer and 30kg of compound fertilizer) per mu of fruit forest planting land as base fertilizer, then leveling and raking fine, making shallow ditches side by side with the tree rows on the ground, with a distance of 15 cm to 18 cm and a width of 6 cm to 8 cm, and then arranging tubers in each ditch according to the spacing of 10 cm. Tuber buds head up, planted after covering the soil, in order to not see the tuber is appropriate.

Herbicide Pinellia ternata tuber should be sprayed with 50% Acetochlor EC in time within one or two days after planting, which can inhibit the growth of annual Gramineae weeds; in the plant growth period, if there are many weeds, it can be controlled with Wenzite or 8% efficient herbicides.

Fertilization due to the dense row spacing of Pinellia ternata, it is inconvenient to topdressing after sowing, therefore, sufficient base fertilizer should be applied. When the seedling height is 20 cm, 1000 kg of water (or thin human and animal manure water) can be poured on the soil surface with 10 kg urea per mu to promote plant growth, accelerate tuber expansion and help to increase yield.

There are few diseases and insect pests in the land where the disease is first planted in Pinellia ternata, and leaf spot disease and virus disease sometimes occur, which can be controlled with 1 ∶ 1 ∶ 120 Bordeaux solution and 65% Dysen zinc 500 times solution respectively.

The tubers of Pinellia ternata can be harvested in autumn and winter after the tubers are sown in spring. When the stems and leaves wither and turn yellow, pick up the tubers carefully on a sunny day, shake off the sand, and put them into the basket. After taking it back, separate the fresh tubers according to size, and the tubers less than 1 cm in diameter can be reserved as seeds and stored with wet fine sand; the tubers with a diameter of more than 1% can be peeled and dried to become a commodity.
