Scorpion is one of the world's four nuts with good economic and ecological values. In guizhou, four plants are found to be strangulations, imitating, imitating, imitating, imitating, imitating, imitating, imitating, imitating, imitating, imitating, etc。

The maturation period is related to species, the growing environment and climatic conditions. In late july to early august, guizhou's maturation period was marked by a period of late maturation between the late july and early august. When the colours of the sorghum and the tops are taken from white to tan, tools are needed to assist in seeding. Attention needs to be drawn to the need for sorghums to be sufficiently mature to facilitate seed breeding and the timely collection of grounded nuts。
2 seed treatment
The nuts can be removed from the nuts by hand after the tan of the tungsten, the tungsten, and the adjusted corn degravator can be used for the hard fruit。
3 drumbs
Skin, seed skin, embryos all contain material that inhibits seed growth and therefore requires low-temperature accumulation and hormonal treatment, leaching water late in december of the year before the seeding, insisting on one change of water per day, once most of the seeds are sunk, extracting filters, immersing 24 h of the 80 mg/l chromium solution, extracting dry surface moisture, then placing the seed layer at 1 °c ~ 5 °c wet leachate or wet sand, flipping the seed once a week, opening the air to 3 - 5min, constantly checking the water fraction, filling the water in time to avoid the drying of the seed, accumulating the layer around 80 d, moving to room temperature, sprung the sand, rolling the seed once a day, starting to sow when the seed's embryo has just broken the skin. Of course, it is possible to use outdoor natural accumulations, to open 10 cm deep ditches on sapbeds, to load seeds into the nylon pocket, and then spread them evenly in dug ditches, around 5 to 8 cm of dirt, with a small amount of scrawl, etc. Falling leaves, and sowing them after a year。
4. Selection of nursery grounds
It is appropriate to plant soil in the form of loose and fertile sandy sandy soil, by choosing plots with flat terrain, small slopes, near water sources, easy drainage, adequate light and backwind。
5 land as a whole
For the seeding fields, the fall of the previous year would be 20-30 cm deep, combined with the application of bottom fertilisation. It's gonna be 120 cm wide, 15 to 20 cm tall, and it's gonna be flat, and three to five days before the seeding, and it's gonna be 60 cm wide with tweed。
6 seeding
It is best to sow wild saplings as early as possible without the effects of night frost, with 6-8 cm seeding of adjoining particles, 20 cm bed spacing, and 5-6 cm seed spacing. A deep 5 to 6 cm ditch on the flat surface or bed, followed by a wet sand-scaved pure seed being spilled to the bottom of the ditch at the distance of the line, covered with 3 to 5 cm thick soil, which would then be able to hold down slightly。
