How many Jin of Polygonatum can be harvested in one mu of land in a few years?

How long it takes to harvest Polygonatum sibiricum is related to its planting method. If it is planted by transplanting roots, it usually takes 1-2 years to harvest, and if it is planted by sowing, it usually takes 3-4 years to harvest. Polygonatum sibiricum can be harvested in spring and autumn, but the quality of the rhizome harvested in late autumn and early winter is good, and its rhizome is fat and full at this time.

First, how many years can Polygonatum be harvested?

1, Polygonatum sibiricum planting cycle

It takes several years for Polygonatum sibiricum to be harvested after planting, mainly depending on the planting method. If it is planted by transplanting roots, it usually takes 1-2 years to harvest, and if it is planted by sowing, it usually takes 3-4 years to harvest.

2. Harvest time of Polygonatum sibiricum

(1) Polygonatum sibiricum can be harvested in both spring and autumn, but the quality of rhizome harvested in late autumn and early winter is better, because its rhizome grows fatter and fuller at this time.

(2) After the rhizome of Polygonatum sibiricum is dug, the soil on it should be washed to remove fibrous roots and diseased scars. The medicine can be steamed in a steamer 10-20 minutes. After steaming, you can take it out and rub it in the sun or bake it until it is completely dry.

Second, how many Jin can Huang Jingyi collect per mu of land?

1, yield per mu of Polygonatum sibiricum

The yield per mu of Polygonatum sibiricum is generally related to its planting methods, planting years and other factors. In the case of conventional planting, the yield per mu of 3-year-old Polygonatum sibiricum is usually about 1500-2500 kg, the yield per mu of dry goods is usually about 300-500 kg, and it can reach about 600 kg/mu at high yield. If it is a 2-year-old Polygonatum, the yield per mu is generally about 50-60% of that of a 3-year-old Polygonatum.

2. How to make Polygonatum yield high?

(1) Early spring, late March and before rainy season is the suitable period for tuber propagation and germination. 1-3 years old Polygonatum sibiricum, healthy and disease-free, can be cut into several sections, each section is 2-3, the wound is collected with ash, dried in the shade for a few days, and put into the ground to germinate after the wound is healed, and the row spacing is 10 cm.

(2) After paving, use rooting powder and carbendazim to spray thoroughly in water, and then cover the soil (take ditches on both sides of Polygonatum sibiricum and cover the soil in the ditches) for 2-3cm.

(3) In the second half of the year, from September to June, 65438+ 10, all the tubers can be transplanted to the field after germination. The tubers cultivated by accelerating germination have high emergence rate, neat emergence and high yield.
