Detailed Guide to Herbicide Application Techniques in Licorice Fields (Part Two)
Weeds can severely affect the yield and quality of licorice, competing with licorice for sunlight, water and nutrients. Some weeds are also intermediate hosts for licorice crop pests and diseases, helping pests and diseases spread and transmit. Especially for artificially cultivated licorice at the seedling stage, if weeds are not removed in time, a large number of seedlings will die, or even the entire crop will be destroyed. Now, in addition to manual weeding, chemical herbicides are often used for weed control. In our county, the following 3 chemical herbicides are currently promoted for artificially cultivated licorice: acetochlor, pendimethalin, and doucaote. Practice has proved that using chemical herbicides for weed control is the guarantee

Key Techniques for Growing Eggplant in Open Fields in Summer
Eggplant likes water. During the long drought with no rain in July, water must be added to keep the soil moist. When watering, dissolve the fertilizers ammonium bicarbonate, monoammonium phosphate and potassium sulfate in water, at concentrations of about 0.3%, 0.15% and 0.2% respectively. When irrigating through furrows, first fill a furrow with plenty of water, then evenly scatter the above fertilizers into the furrow to dissolve; the application rates per mu can be 15-30 kg, 10 kg and 10 kg respectively. If there is no water shortage, a hole can be dug in the middle of every four eggplant plants, and fully decomposed farmyard manure can be placed in the hole. Note that topdressing should be

Detailed Explanation of Key Techniques for Direct Seeding and Seedling Cultivation of Schisandra chinensis in Open Fields
Select a sunny plot with loose soil, flat terrain, moist soil and no water accumulation, and make a low bed 1.2---1.4m wide, 10m long, with a level surface. Sowing uses the drill method. Before the autumn freeze, open shallow furrows 2-3cm deep on the prepared seedbed at a row spacing of 15cm, sow 100g of seeds per bed, cover with soil 3---4cm thick, water thoroughly, press down lightly, then cover with 10cm of leaves or a layer of rice straw to maintain moisture and protect against cold, and remove it when the seedlings emerge. To prevent damping-off and other soil-borne diseases,

Detailed Explanation of Key Technical Points for Chemical Weed Control in Schisandra Fields
In recent years, the production of Chinese medicinal materials in the Dandong area has developed rapidly, especially the cultivation area of Schisandra has increased year by year, becoming a new highlight of economic growth in our region. However, weeds in Schisandra seedling fields and main fields have always been a major headache for medicinal growers. Traditional manual weeding is labor-intensive and time-consuming, and using herbicides can effectively improve production efficiency, but there have been few trials. We conducted trials on chemical weed control technology in Schisandra fields with relatively large cultivation areas and achieved good results. 1. Survey results of weed species in Schisandra fields show that in Dandong

How to control pests and weeds in single-season rice seedling fields? Here are the control recommendations
I. Weed control in seedling fields 1. Weed control before plowing: 7-10 days before plowing the seedling bed, use 41% glyphosate 150 ml/mu or 10% glyphosate 1000 ml/mu diluted in 30 kg of water for fine spraying to control old weeds before sowing. 2. Weed control after sowing: ① 1-2 days after sowing germinated seeds, use 17.2% bensulfuron-methyl and piperophos wettable powder (Youhebao) 210 g/mu diluted in 45 kg of water for fine spraying. ② At the needle-standing stage of seedlings, use 40% bensulfuron-methyl and pretilachlor wettable

How to release seedlings after mulching cotton fields with plastic film? Practical tips to share
In plastic-film-mulched cotton fields, the temperature is high, and seedlings emerge quickly and evenly. It takes 8 days from sowing to emergence, and 3 to 4 days after emergence for full stand. After full stand, if the late frost has passed, holes should be broken to release the seedlings. Releasing seedlings too early means they cannot achieve full stand or complete stand; too late is not good for strong seedlings, and if high temperatures occur, it often causes seedling scorching. For drill sowing, holes should be punched according to plant spacing to release seedlings; for hole sowing, holes should be punched according to seedlings. After breaking the film and releasing seedlings, cover the openings with soil to prevent moisture loss, temperature drop, film lifting by strong wind, and weed growth. When releasing seedlings, grasp the principle of releasing green but not yellow, that is, cotton seedlings with flat and expanded cotyledons can be released; yellow-valve seedlings that have not expanded, if released, are easily dried by wind or killed by sun, and cannot be released through holes.

What is the application ratio of special fertilizer for cotton drip-irrigated fields?
I. Total fertilizer application for cotton In high-latitude marginally suitable cotton areas, for a seed cotton yield of 300-380 kg, 70-80 kg of natural fertilizer is needed, equivalent to 160-180 kg of standard fertilizer. This achieves "a jin of fertilizer for a jin of cotton." Applying 1 kg of standard fertilizer can produce 1 kg of lint cotton. Soil test results and cotton plant nutrient diagnosis in Regiment 137 generally show zinc deficiency; applying 1-2 kg of zinc fertilizer in autumn increases yield by 5%-10%. For plots with abundant potassium according to test results, potassium fertilizer application is 5-10 kg, especially

What is the box tree pyralid, an insect found beside vegetable fields?
As spring warms and flowers bloom, insects begin to become active. During a recent science-and-technology outreach activity in the countryside, it was found that a pest called the box tree pyralid had begun to occur and cause damage on boxwood along the roadsides of the park. The box tree pyralid is one of the common pests on plants such as boxwood, small-leaved box, large-leaved box, littleleaf box, Chinese box, spoonleaf box, Korean box, and holly, and it occurs in Shanghai and other provinces and cities. In Shanghai it has 3 to 4 generations per year, with severe overlapping of generations. It usually becomes active in March in spring, begins pupating in mid-April, begins emerging in late April, and the first-generation lar

Detailed Explanation of the Key Cultivation Techniques for Growing Golden Mushrooms in Rice Fields
In the townships of Dongchan, Fenshui, Shidong and others in Anju District, Mianyang, Sichuan Province today, when people mention "open-air mushrooms in rice fields," it can be said that everyone knows of them. "Growing mushrooms in rice fields is great! It doesn't affect the rice and brings very good returns." Uncle Yin from Shuangbaishu Village in Dongchan Town always speaks highly of field mushrooms, "Now, apart from growing mushrooms, I probably can't find any other cash crop that brings in more money than this." It is reported that "open-air mushrooms in rice fields" use wheat straw, rapeseed stalks, corn stalks, rice straw and other materials as raw materials,

Planting Techniques for Intercropping Shrubs in Southern Magnolia Fields
In the first 3 years of southern magnolia seedling growth, to offset the drawbacks of large initial investment and no profitable output from field-planted trees in the early stage, small shrubs such as littleleaf boxwood, golden-leaf privet, and red-leaf barberry can be intercropped. During the first 3 years of intercropping small seedlings, 6000-7000 plants per mu at an average of 0.5 yuan per plant can yield more than 3000 yuan in income. After the 4th year, the southern magnolia has grown to 5-6 cm, and can then be sold selectively at about 80 yuan per plant. From then on, annual sales all generate income. Cultivation points: southern magnolia 1-year
