Farmers who grow gold and silver flowers often suffer from weed problems, with different types of weeding available for different planting scales. In the case of a small plant, for example, one and a half acre, priority is given to pine geophysic weeding, with less herbicide, which is best done after rain or rain。
For three to four times a year, chinese weeds are cultivated, for the first time in the spring, and for the second time in june, for the third time in july-august, and for the fourth time in the early autumn-and-early winter, the roots of the plant are shallower and deeper, avoiding the root damage, and it is necessary to cut the grass in the middle of the winter。
If it is grown in large areas, such as hundreds of acres of rain, or large amounts of rain in the south, with the use of closed herbicides, it is now possible to hit 2+50 with acetylene fluoride, at a low cost of $10 acre, for two to three months, and to block herbs and broad leaves。
If weeds are not available at a later stage, they can be washed, normally at 100 ml 2+50, applied up to 200 ml, and acetylene fluoride is doubled, so that they do not have to be beaten, have a long duration and use up to two times a year, because herbicides are damaging the soil。
Also at a later stage, a bucket of water with two or three pieces of water has good weeding, has no effect on gold and silver and does not damage soil。
Herbicides are regulated and must be used in weeds between the ages of 3 and 5 to avoid high temperatures, best around 25 degrees and less than 10 degrees. The dose is strictly stated and cannot be increased at random, otherwise it is vulnerable。
The formulation is diluted by secondary dilution and sprayers that have used other pesticides must be washed clean. There are also special herbicides for gold and silver flowers, which are internal insorption-guided, suitable for planting dense, artificial grass-cutting fields and saving time。
In addition to these, weed coverage is good, with the highest yield and efficiency being covered by horticultural land and the capacity to produce a large number of dry flowers, and the use of grass curtains, 70 per cent or 90 per cent of sunnets increases the water content of the soil, saves money from artificial weeding, saves water and benefits and is productively available。
Under different moistures, the levels of chloropic acid and wood herbs of gold and silver flowers are consistent with pharmacological standards, without fear of quality。
In addition, the fields of gold and silver can be planted, pre-planted fields, ground-blue roots, etc., and half-summers, wood-woods, etc., later in the production period, which can both use the land and reduce weeds。
