Embodiment 1

[0030] Including the following steps:

[0031] Step 1: Screening of alder indications: Find plots with good alder growth, take soil samples to dry and weigh to obtain the original dry weight of the soil samples, burn the soil samples at 400 degrees Celsius for 4 hours, weigh the burnt The weight of the soil sample after burning, the ratio of the weight difference before and after burning of the soil sample to the original dry weight of the soil sample is the soil organic matter content, and the plot of the soil sample with the soil organic matter content of 20% to 25% is selected to obtain Class A Lot;

[0032] Step 2: Screening of wood sorrel indications: Exclude the plots where wood sorrel grows from the Class A plots selected in the previous step to obtain Class B plots. The soil of Class B plots should have good permeability and It is characterized by aggregate structure, and the soil bulk density is 0.7g / cm 3 , the powder-to-viscosity ratio is 0.6, and the pH value is 6...

Embodiment 2

[0039] Including the following steps:

[0040] Step 1: Screening of alder indications: Find plots with good alder growth, take soil samples to dry and weigh to obtain the original dry weight of the soil samples, burn the soil samples at 300 degrees Celsius for 3 hours, weigh the burnt The weight of the soil sample after burning, the ratio of the weight difference before and after burning of the soil sample to the original dry weight of the soil sample is the soil organic matter content, and the plot of the soil sample with a soil organic matter content of 15% to 20% is selected to obtain Class A Lot;

[0041] Step 2: Screening of wood sorrel indications: Exclude the plots where wood sorrel grows from the Class A plots selected in the previous step to obtain Class B plots. The soil of Class B plots should have good permeability and It is characterized by aggregate structure, and the soil bulk density is 0.6g / cm 3 , the powder-to-viscosity ratio is 0.5, and the pH value is 5.5...

Embodiment 3

[0047] Including the following steps:

[0048] Step 1: Screening of alder indications: Find plots with good alder growth conditions, take soil samples to dry and weigh to obtain the original dry weight of the soil samples, burn the soil samples at 500 degrees Celsius for 5 hours, weigh the burnt The weight of the soil sample after burning, the ratio of the weight difference before and after burning of the soil sample to the original dry weight of the soil sample is the soil organic matter content, and the plot of the soil sample with a soil organic matter content of 25% to 30% is selected to obtain Class A Lot;

[0049] Step 2: Screening of wood sorrel indications: Exclude the plots where wood sorrel grows from the Class A plots selected in the previous step to obtain Class B plots. The soil of Class B plots should have good permeability and It is characterized by aggregate structure, and the soil bulk density is 0.8g / cm 3 , the powder-to-viscosity ratio is 0.8, and the pH v...

Abstract

The invention provides a quick land selection method for panax notoginseng planting areas. The steps include: looking for land blocks with good Alnus cremastogyne growth conditions to obtain type A land blocks; excluding Oxalis corniculata growth land blocks from the type A land blocks to obtain type B land blocks; excluding panax notoginseng and vegetable crop planted land blocks suffering stem leaf yellowing to obtain type C land blocks; in the type C land blocks, excluding the land blocks in which forecrop plants have more than 10 tuberous roots and root knots, thus obtaining type D land blocks; in the type D land blocks, selecting land blocks with more than 20 years of crop rotation, thus obtaining type E land blocks; and in the type E land blocks, excluding land blocks using non-decomposed organic fertilizers so as to obtain type F land blocks, i.e. panax notoginseng planting areas. The method provided by the invention improves the land selection efficiency, lowers the risk of planting, lays a good foundation for guaranteeing the yield and quality of panax notoginseng plants, effectively reduces the field management difficulty in the process of planting, the method is simple and reliable, and is easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for rapid site selection of a Panax notoginseng planting area. Background technique [0002] Panax notoginseng, also known as Tianqi, is an Umbelliferae Araliaceae plant, mainly distributed in Yunnan, Guangxi, Jiangxi, Sichuan and other places. Chinese herbal medicine Panax notoginseng uses its root as a medicinal part, which has the effects of dispelling blood stasis, stopping bleeding, reducing swelling and relieving pain. Indications for hemoptysis, hematemesis, hematochezia, metrorrhagia, traumatic bleeding, chest and abdomen tingling, swelling and pain from falls. Panax notoginseng is a traditional precious Chinese herbal medicine in my country, one of the 40 kinds of large medicinal materials. It has a history of more than 400 years of application and has a long-standing reputation at home and abroad. Sanqi has been known as the "hemostat...
