1、 How to sow:

(1) From September to October, the fruit of this plant has fully matured. At this time, we can collect the fully mature pods, and then put them in a flat place to dry. After the peel has dried, the seeds will fall down by themselves, and then we can collect the seeds. Gather the seeds together, then pick out the sundries and throw them away. Then put the seeds in woven bags and store them in a dry place

(2) Prepare the seedbed for cultivating buds and seedlings. Generally, sandy soil is selected as the cultivation substrate, and the seedbed is selected in a relatively flat place. There is no requirement for the orientation of the bed, whether north-south or West-East. If it is a relatively gentle sunny slope, it can also be used as a seedbed. The bed should be about 1 to 1.2m wide and 0.15 to 0.2m high. The length of the bed depends on the ground conditions, generally 20 to 50cm. After it is done, the surface of the bed should be sprinkled with farm livestock and poultry fertilizer, about 500 kg of fertilizer per 100 square meters, and then turn the bed 15 to 20 cm deep with a rake, so that the soil can be fully integrated with the fertilizer

(3) One week before sowing, put the seeds into the bottom of a container, and then pour water about 10 times the volume of the seeds into the container, immerse the seeds, and the water temperature should reach 70 degrees. Wait until the next day to pour out the water, then mix the sand three times the volume of the seed with the seed, put it in the woven bag, and control the temperature to 20 to 25 degrees for storage

(4) Generally, sowing is selected from April to early May. Dig out the seedbed with a rake with a spacing of 25 cm and a depth of 4 cm. Sprinkle the seeds. The spacing between seeds should reach 3 to 4 cm. Then cover the seeds with a layer of soil 2 to 3 cm thick, and then compact the soil

2、 Note:

(1) The collected seeds should be stored in a dry place

(2) Sprout before planting
