What medicine can be used in cotton fields?

In recent days, some farmers have asked which Chinese herbal medicines can be used in cotton fields. We know that after the middle and late April of the Gregorian calendar, the cotton fields in Hebei Province began to sow cotton from south to north, and most of them use mulching to increase the temperature. Regardless of early sowing or late sowing, the height of the seedling is usually about 33 cm when cotton is grown to the grazing season. To prevent the growth of the cotton seedling stage, the cotton field planting variety must be selected. The harvested medicinal herbs strive to achieve the principle that the cotton drugs do not affect the growth of each other. During the full use of the cotton seedlings, the intercropping Chinese herbs are matured and harvested before and after the “mountain seed” to allow the cotton to grow normally. Suitable for intercropping with cotton are the following:

1. The king does not stay. It is a two-year-old or annual herbaceous plant with medicinally mature seeds. The king will not be planted with a plant height of 50-60 cm, and the mature grazing section is harvested. The normal yield is about 200 kilograms per mu. Since the intercropping area is less than normal, the sown area should be reduced by 50%, and the yield per mu is about 100 kilograms. Its sowing date is for the end of autumn or early spring sowing of seedlings, and the use of seed for 1 kg per mu. If intercropping with cotton, it should be sowed in advance in the middle of the broad cotton field and broadcast only one line. The position of sowing cotton is still left, because the king does not stay in the line for a short period of growth, the maturity time is the same, the general year and wheat mature at the same time, there is no pest during the growth period, belong to the stable production of medicinal species.

2. Mustard seeds. Is an annual herb, with mature seeds as medicine, the price is stable, about 9 yuan per kilogram, generally 100 kilograms per mu, but also because of the intercropping with cotton is equivalent to less than 50% of the area, per mu yield should also be 50 kilograms, it's mature In the same period as wheat, the per mu sowing rate is 1 kilogram, and the adult planting height is about the same as that of wang fengju. It is sown in the middle of the cotton field, and after harvesting the mustard seeds, it remains as a working track. White mustard seeding is usually planted before the thrilling festival. It is about the same height as the king of Vaccaria. The height is 10-15 cm. It is advisable to keep a seedling at a distance of 10-15 cm. There may be pests in the seedling stage of white mustard, so it must be before flowering. In addition to rule once. To ensure stable production of mustard seeds.

The above two medicinal herbs are harvested from green to yellow on the ground and harvested when they are nearly dry. They are transported to the field and dried to lay seeds. The impurities are removed and dried and preserved for sale.

There are also many farmers who ask whether they can make Radix Isatidis, Pinellia, and Safflower in the cotton fields. I think it is not appropriate to do this. Banlangen, Pinellia are all happy, Banxiaxi is humid, Banlangen is semi-arid, and there is no photosynthesis for growth. Extremely unfavorable. In addition, the growth period of cotton is approximately the same, affecting field operations during cotton growth. The red peanuts are long-term and can only be harvested after the summer solstice, and the safflower plants are up to one meter high and affect the growth of cotton. Therefore, intercropping is not recommended.
