What is the efficacy and function of corn stigma boiling water?

Lysine, magnesium, cellulose, carotene, etc. Corn can not only cure cancer, resist cancer and prevent cancer, but also enhance people's brain power, which is beneficial to health and beauty. Corn silk can be boiled and drunk. Next, I will learn the efficacy and function of corn stigma boiling water with you.

The efficacy and function of corn stigma boiling water The cellulose content in corn is very high, which can protect the stomach and promote gastrointestinal peristalsis, and the corn stigma is sweet and flat. Other nutrients can enhance human metabolism, regulate nervous system function, make skin soft and smooth, and inhibit and delay the generation of wrinkles. In traditional Chinese medicine, corn beard tea, also known as long beard, is sweet and flat, and has a wide range of preventive and health care uses. Because corn is wrapped in corn bags during the growth process, it needs to rely on corn stigma to absorb nutrients, so corn stigma contains many vitamins and other nutrients, which can not only cool blood and reduce fever, but also eliminate damp heat in the body, induce diuresis and reduce swelling. After making tea, it is a good slimming drink.

In traditional Chinese medicine, corn stigma has a wide range of preventive and health care uses. Traditional Chinese medicine believes that it can induce diuresis to reduce swelling, clear away heat, calm the liver and promote gallbladder function, and can also resist allergy, and treat nephritis edema, hepatitis, hypertension, cholecystitis, gallstones, diabetes, sinusitis and mastitis. Replacing tea with boiled water can relieve summer heat. Regular drinking can reduce weight, which is of great benefit to the prevention and treatment of atherosclerosis and hypertension. Patients with hyperlipidemia, hypertension and hyperglycemia can reduce blood lipid, blood pressure and blood sugar.

Fertilization management method in the middle and late stage of maize planting 1. Ear fat Generally, nitrogen fertilizer is applied again at the big bell mouth stage, accounting for about 50% of the total topdressing, and the standard nitrogen fertilizer is 30-40 kg per mu. 2. Granular fertilizer. Generally, it accounts for about 10% of the total topdressing, and ammonium bicarbonate topdressing per mu 10 kg. When applying fertilizer, a ditch with a width of 10-15 cm and a depth of 9- 12 cm should be opened at a distance of10 cm from the plant. After fertilization, the ditch should be covered with soil and watered.

Pests and diseases control corn borer (2349,8.00,0.34%) with 3% phoxim granules 1.5-2 kg and 5-6 kg of fine sand per mu, or with 50% phoxim emulsifiable concentrate, 0. 1% toxic soil is prepared and spread in the heart leaves of corn, which can be controlled at the ear stage. To control corn leaf spot, spray 50% carbendazim 500-800 times; In order to control corn rust and brown spot, 20% triadimefon EC 75- 100 ml was sprayed per mu at the early stage of the disease.

Emasculation of corn is helpful to increase production. Castration can reduce nutrient consumption and promote the development of female ears; Reduce plant height, improve ventilation and light transmission conditions, and enhance lodging resistance; Overcoming the phenomenon of disjointed flowering of male and female panicles is beneficial to the meeting of flowering periods and improving the seed setting rate; Reduce the harm of stem borers. It is necessary to grasp the time of castration. It is difficult to operate in the early stage, and the tassels are too tender, which is easy to break or bring out the heart leaves. If it is too late, the nutrient consumption is too high, and the yield increase is not significant. The suitable time for emasculation is that the tassel is pulled out about one-third to one-half of the heart lobe. When the hand can hold it, it can be pulled out with a little force. It is best to operate on sunny days from 9 am to 4 pm, so that the wound can heal easily. The number of emasculated plants generally accounts for about one-third of the total number of plants in the whole field, and at most it does not exceed half. Generally speaking, emasculated plants are staggered or separated. Two rows near the ground and two plants in the field cannot be emasculated, so as not to affect pollination. The auxiliary pollination effect is better after emasculation.

Farmers are used to harvesting corn when the bracts turn yellow and the top becomes hard. According to years of practice, early harvest and low 1000-grain weight affect the yield. The sign of corn maturity should be the disappearance of milk line. At this time, the 1000-grain weight is high, which can increase the yield by 8%- 10% compared with the traditional harvest period. On the same ear, the upper grain milk line formed first and disappeared early; The milk line at the base of spike formed late and disappeared late. When determining the suitable harvest time, the milk line at the lower part of the ear should prevail.

Management method of summer maize planting in the middle and late stage 1. Use water and fertilizer skillfully to promote the end. Summer maize has a short growth period and concentrated demand for water and fertilizer, so it should be popularized to the end.

1, early irrigation and water saving, early application of jointing fertilizer. At jointing stage of summer maize, its growth characteristics are mainly vegetative growth, with leaves growing on the ground and underground packaging, which requires a lot of nutrients and tight fertilization time. Therefore, stubble breaking, watering and fertilization must be carried out before the jointing stage of summer maize to promote the early development of seedlings. For general fertility plots, decomposed organic fertilizer 1500 ~ 2500 kg is applied per mu, and fertilizer is mixed, and 20 kg of urea and calcium superphosphate are applied per mu. Fertilization methods are point application or strip application, and unscientific fertilization methods such as spreading application, open application and water application are prohibited.

2. Fully pump the public water and fill the slurry. About half a month before tasseling is the differentiation period of female ear and floret. In case of drought at this time, artificial irrigation should be carried out to prevent neck drought. Irrigation is also very important during pulping. At this time, if the soil moisture is not good and the weather is dry, it will be prone to sunburn and greatly reduce production.

3. Topdressing fertilizer at booting stage (1 1 Ye Zhan) is suitable for topdressing grain fertilizer. Generally, fertilizer at booting stage accounts for10% ~15% of fertilizer applied (10 ~12kg/mu). At this time, vegetative growth and reproductive growth are parallel, so it is also the key topdressing period of corn. For some late-maturing varieties or plots with sandy soil, fertilizer removal occurs before and after tasseling, so it is appropriate to apply attack fertilizer and topdressing, not too large, but early.

Second, prevent lodging and reduce production. Recently, due to the heavy rainfall and strong wind in summer, it is particularly important to prevent maize from lodging in the middle and late stage. Generally speaking, we should pay close attention to the local weather forecast before irrigation, and prohibit irrigation when heavy rain comes. After the rain stops, irrigate again. In case of accommodation, you should tidy up in time.

Third, artificial emasculation and auxiliary pollination. The combination of emasculation and artificial pollination has a more significant effect on yield increase. Method of emasculation: When the tassels have just been plucked and the flowers have not been fully blossomed. Generally, it is interlaced or one tassel is removed every two lines, and it is also possible to emasculate every other plant. Castration should be carried out in fields with neat growth, high density and light pests.
