Embodiment 1

[0092] (1) Harvest year

[0093] a. Field cleaning

[0094] After the three-year commodity 7 is harvested in September, remove the sunshade nets, iron wires and field posts of the shade shed in the field in time, store the posts, iron wires and sunshade nets well, and put the field grass (pine hair) together with the remnants of notoginseng All the bodies were cleared out of the field for burning.

[0095] b. Sun exposure and frost sterilization

[0096] In winter, let the old Qiyuan furrow noodles be exposed to the sun and frost in the sun to kill field germs. At the same time, remove the accumulated soil in the furrows to facilitate drainage in the field, and wash off the excess salt ions in the bed surface soil in time.

[0097] (2) The first year

[0098]a. In spring, the bed surface is turned shallowly to plant corn.

[0099] At the beginning of May, after a soaking rain, spread a layer of quicklime (application rate 50 kg / mu) and calcium magnesium phosphate fertiliz...

Embodiment 2

[0135] (1) Harvest year

[0136] a. Field cleaning

[0137] After the three-year red-seed Panax notoginseng is harvested in December, remove the sunshade net (or roof grass), iron wire and field pillars in the field to build the shade shed in time, store the pillars, iron wire and sunshade net, and put the field box grass ( mountain grass) together with the notoginseng remnants are all removed outside the field for burning.

[0138] b. Sun exposure and frost sterilization

[0139] After cleaning and removing impurities in the field of Laoqi Garden, let the border of Laoqi Garden directly expose to the sun and frost in winter to kill field germs.

[0140] (2) The first year

[0141] a. In spring, the field is filled with water and plowed to plant rice.

[0142] After the rainy season comes in May, the field is soaked with water, and rice is directly planted after plowing with a rotary tiller. Use paddy and dry crop rotation, fully absorb and utilize the residual fertilizer...

Abstract

The invention discloses a method for shortening a rotation cycle of panaxnotoginseng. The method comprises a first step of performing field clearing, impurity removal, exposure and frost sterilization in the harvest year; a second step of on a first year, performing soil sterilization and adjusting a soil pH value in spring, planting corn or rice after shallow plowing, performing straw burning and earth baking and deep tillage of soil and drying in the sun, and planting green manure; a third step of on a second year, performing green manure harvesting overturning pressing in spring, improving the soil, perform soil preparation to plant marigold, and in autumn enabling marigold straw to return to fields to kill underground nematodes, and performing soil preparation to plant wheat; a fourth step of on a third year, harvesting the wheat in spring and enabling the straw to return to the fields, performing soil preparation to plant upland rice, harvesting the upland rice in autumn, performing deep tillage of soil and drying in the sun, applying a soil conditioner and a continuous cropping soil correction special fertilizer, performing piling and building sheds in winter, opening an air window, performing soil preparation to form rectangular pieces of land in the fields, and planting panaxnotoginseng. According to the method, panaxnotoginseng can continue being planted in planting land parcels at an interval of three years, continuous cropping obstacles are effectively prevented, the rotation cycle of panaxnotoginseng is shortened, and the method is simple and practical.

Description

Technical field: [0001] The invention relates to a method for preventing and controlling the obstacle of continuous cropping of notoginseng and shortening the rotation period of notoginseng, which belongs to the planting technology of Chinese medicinal materials. Background technique: [0002] Sanqi (Panax notoginseng (Burk.) F.H.Chen) is a plant of the genus Ginseng in the Araliaceae family. Panax notoginseng is also a unique biological resource in my country. Its roots and rhizomes are mainly used as medicine, which has the effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain. Wenshan and its surrounding areas in Yunnan are one of the production areas of Sanqi and the largest production area of ​​Sanqi at present, and are named "the hometown of Sanqi in China". The annual planting area of ​​Wenshan Panax notoginseng is 10Khm 2 , the annual output reaches 10 million kilograms, the annual agricultural output value is nearly 6 ...
