Harvest and processing of licorice
Harvest time is generally late autumn and early spring, generally after autumn leaves wither best, at this time harvest licorice root, quality firm, weight, powder, sweet, will dig licorice soil (do not wash with water), while fresh with a guillotine or sharp knife head and root branches from the main root part cut off, according to the diameter of the root head divided into first and second class, hairy grass, generally dry coarse head diameter of more than 1.5cm for first class, diameter of 0.3-1.4cm for second class, Less than 0.5 cm into the grass, first-class, second-class licorice, its roots can not be shorter than

Cotton angular spot
The disease is harmful not only to cotton seedlings, but also to adult stems and leaves and developing cotton bolls. At the seedling stage, the infected cotyledons showed waterlogged irregular or round spots, dark brown, and the severe cotyledons withered and fell off. The back of the infected leaves first produced dark green dots, then expanded into oil-stained ones, and the disease spots on the front of the leaves were polygonal, and sometimes the disease spots expanded in irregular strips along the veins, resulting in withered and yellow leaves. Stem infection present water status of the main disease spot, and then expand and blacken or rot, the disease part is sunken, the germs bend to one side. The top bud infection forms a "rotten top", resulting in the death of the whole plant.

New cultivation techniques of simple dwarf and dense cotton
The main content of cotton "simple, short and dense" cultivation technology is based on transgenic insect-resistant cotton, using chemical weeding to reduce mid-tillage, simplified pruning supplemented by chemical control, wide row close planting, water fertilizer regulation, comprehensive control of diseases and insect pests, etc. to achieve the cultivation goal of dwarfing and dense planting, increasing production and increasing efficiency. The yield index is 20000kg per mu of seed cotton, and the yield structure is as follows: density 4000mu / mu, boll number 55000kg / mu, boll weight 4.0g / mu. The fertility process is: April 15 ~

Application methods of several Chemical Control agents for Cotton
The chemical regulators commonly used in cotton production are meth, butene, ethephon, triacontanol, chitin and so on. Some of these chemical regulators can shape ideal plant types and form groups with high light efficiency per unit area; some can promote plant growth and reduce the occurrence of diseases and insect pests; and some can promote ripening and effectively regulate the mature period. so as to reduce the harm of disastrous weather. In short, the scientific use of various chemical control agents in cotton production is beneficial to the improvement of yield and quality. 1. Ketamine can not only reduce cotton plant height, but also reduce cotton plant height.

Acute wilt of cotton?
There are many types of symptoms in the adult stage of Fusarium wilt. Leaves can also be shown as yellowing type, reticulate type and other types, easy to fall leaves. The top leaf of the seriously diseased plant is wrinkled and deformed, the color is dark green, the Internode is shortened, and the plant type is short. Acute wilting type often occurs after rain, and the cotton plant suddenly loses water. The leaves quickly withered and withered, the leaves drooped, and the leaves often fell into poles. Cotton Fusarium wilt mainly overwintered in diseased plant seeds, diseased plant residues, soil and manure. The transportation of bacterial seeds and cake fertilizer is the main cause of the disease in the new disease area. Tillage and Management of Cotton Field in Disease area

Mechanized Micro-bowl Seedling raising Technology of Cotton
The traditional nutrition bowl seedling raising method has some shortcomings, such as too much labor, complex seedling bed management, high transplanting labor intensity and so on. The mechanized micro-bowl cotton seedling raising technology developed by the Economic Institute of Jiangsu Academy of Agricultural Sciences and Jiangsu Agricultural Technology extension Center broke through the traditional mode of cotton seedling raising by manual operation for a long time, and achieved the goal of labor-saving and labor-saving in cotton seedling raising. At present, the mechanized micro-bowl seedling raising technology is in the experimental and demonstration stage, and it has not been popularized and applied on a large scale, and farmers do not fully understand and master the technology. For this reason, our reporter discussed the advantages, disadvantages and details of mechanized micro-bowl seedling raising.

Advantages and disadvantages of cotton machine sowing
In recent years, cotton sowing in Ninghe County has always been maintained at about 300000 mu, accounting for more than 50% of the arable land. Since the introduction of experimental and demonstration machine sowing technology in 2002, the popularized use area has reached more than 70% this year, injecting new vitality into cotton production in Ninghe County. The main methods are as follows: first, carry out machine ploughing, winter irrigation or spring irrigation, preserve soil moisture before sowing, flatten the soil with sowing seeds, then spray herbicides on the surface, and then sow seeds with a seeder: ditching, fertilizing, sowing, soil mulching, film mulching, and running water operation.

Cotton chemical control is fastidious.
In recent years, with the widespread application of insect-resistant cotton, plastic film mulching and chemical control technology, cotton farmers have some bad cultivation tendency in cotton cultivation technology, especially in chemical control technology (hereinafter referred to as chemical control). If we do not pay attention to timely and appropriate chemical control, the cotton field will grow excessively, the vegetative growth is too prosperous, and the buds, flowers and bolls fall off seriously, which eventually leads to the formation of high, large and empty cotton plants, and serious lodging in the later stage of wind and rain, resulting in great losses. In chemical control, we should aim to stabilize the shelf of high yield, increase buds and protect bolls, and master the "look at the sky, the earth and the seedlings".

Cotton chemical control technology
Cotton chemical control is the use of chemical control means to shape cotton into an ideal plant type and create a population with high light efficiency. 1. Chemical control status and function of cotton is a typical light-loving crop. High yield, early maturity and high quality of cotton in the precocious cotton area of eastern Hebei need to be realized by reasonable close planting, but reasonable close planting will inevitably aggravate the contradiction in the utilization of space and light energy between individuals and groups in the middle and later stage. Therefore, cotton chemical control has become an important supporting measure for reasonable close planting, and it is also the core content of promoting early stress resistance, especially simplifying the cultivation technology system. At present, Ketamine is used in cotton chemical control.

Cotton overblending can be relieved skillfully.
From late July to early August every year, many cotton farmers in cotton areas report that there is a phenomenon of vigorous growth of some cotton in the previous stage, and some even show a trend of crazy growth, so they use the plant growth regulator Dextromethamine. Due to the inability to control the concentration, when the application concentration was too high and encountered high temperature, the cotton plant showed the phenomenon that the branches and leaves could not expand, and the growth of cotton was inhibited. Here are several ways to alleviate the growth of cotton: spraying Huimanfeng active liquid fertilizer, which contains chelated humates and multi-component compound fertilizer
