Techniques for Planting Pueraria thomsonii

Soil preparation: select the land with deep soil layer, fertile soil and convenient drainage and irrigation, remove sundries and disinfect, and then dig ditches to make beds. | | transplant: New Year's Day can be transplanted on a sunny day after transplanting. Phosphate fertilizer should be applied after transplanting to compact the soil. | | tending: timely seedling replenishment, setting up and pruning vines, and at the same time, do a good job in water, fertilizer and pest control.

The nurturing work of Pueraria lobata:

1. Replenish seedlings

16500 plants per hectare were planted according to row spacing of 1m and plant spacing of 0.6m. After transplanting, the survival of the plant should be checked in time, and those with missing seedlings should be replanted as soon as possible. It is best to use a kind of seedling with a piece of kudzu, and the lower stem next to the missing seedling can also be pressed into the soil by the pressing method when the seedling is deficient, and then cut off between the new seedling and the top seedling after the stem grows.

two。 Set up a frame to straighten the vine

Pueraria lobata is a kind of vine climbing plant, which needs to build a frame to facilitate its climbing growth, minimize its contact with the ground, promote root expansion and obtain high yield. When the kudzu vine grows to 50 cm, it should be set up in time to draw vines, each leaving 1-2 vines, using 2-meter-long bamboo poles or wooden poles to form a "human"-shaped scaffolding. Pruning and pruning the vines in time, remove the lateral vines and old leaves below 1.5 meters of the main vine in time, and let the lateral branches grow above 1.5 meters. After the following spring, pruning as early as possible, each plant retains 2-3 vines to form a main vine, leaving no branched lateral vines within 1 meter.

3. Soil fertilizer and water management

Timely ploughing and weeding can be carried out for 2-3 times according to the growth of weeds. Radix Puerariae has the effect of nitrogen fixation and does not need too much fertilizer in the process of growth. The first topdressing was carried out 20 days after planting, and water fertilizer was applied thinly, the compound fertilizer could be applied 60-75 kg / ha, and then every 7-10 days to promote root growth. After March, 450 kg / ha compound fertilizer was applied every 30 days. Cultivate the soil and clear the ditch and discharge the stagnant water in time. Pueraria lobata is a dry land crop with well-developed root system, drought tolerance and waterlogging tolerance, and drainage should be kept smooth in the rainy season.

Pueraria lobata enters a dormant period in winter every year, which is the best time to harvest.
