New Cotton Cultivation Technique: Saving Labor and Increasing Yield at the Same Time
This technique is based on the cotton cultivation method in which cotton is not pruned or disbudded, but only the terminal bud and side buds are removed, also called the two-time topping cultivation method. On that basis, a more labor-saving one-time topping cultivation method has been introduced. It saves at least 70% of labor, while increasing yield by more than 8%, and cotton quality is basically on par with the traditional method. Its key techniques are as follows: 1. Select good varieties and keep the sowing date moderate. It is advisable to choose large-plant types with strong mid-season growth, with seed cotton yield per mu of no less than 350 kg and high-yielding varieties exceeding 500 kg. Usually, the Hua Kang III series, Qiufeng Large Boll series, and disease-resistant

Clever Fertilization in the Late Stage of Cotton: Disease Prevention and Yield Increase at the Same Time
In the late growth stage of cotton, the root system's ability to absorb nutrients declines noticeably, but if fertilizers such as nitrogen, phosphorus, potassium, zinc and boron are sprayed on the cotton leaves, they can prevent premature senescence, promote early maturity, prevent disease, prevent boll shedding and help set large bolls, with a significant yield-increasing effect. 1. Apply nitrogen fertilizer to prevent premature senescence: each time use 75-100 kg of 1% urea solution per mu, spray once every 5-7 days, for 2-3 consecutive sprays, which can enhance leaf photosynthesis and prevent premature senescence and increase yield. 2. Apply phosphorus fertilizer to promote early maturity: in the late stage of cotton, spraying phosphorus fertilizer on the leaves,

Autumn and winter nourishment is not the same as fish and meat medicinal diets
Autumn and winter nourishment ≠ fish and meat medicinal diets! Chinese people have had the custom of nourishing the body in autumn and winter since ancient times. With social development and rising living standards, autumn and winter nourishment is no longer simply equated with ginseng plus astragalus, and the way of nourishing should change. A balanced diet is the foundation. We all know that protein, carbohydrates, fat, vitamins and minerals are all nutrients the human body needs. However, many people's daily diets are very unbalanced, with unreasonable combinations of meat and vegetables, too little grains and coarse grains, and too much meat. Combined with a lack of exercise, this has led to steadily rising incidence rates of high blood pressure, diabetes and obesity.

Detailed Explanation of Key Points for High-Yield Cultivation Techniques of Black Sesame
There are many varieties of black sesame. "Zhongzhi No. 9", bred by the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences, is the foremost variety. This variety is of the branching type, with a yield of up to 58.33 kg per mu. The growth period for summer sowing is 95 days. The seed coat is jet black, with a 1000-grain weight of 2.63 grams. The oil content reaches 47.3%, and the protein content is over 21%. This variety has strong resistance to stem blight and is a variety worth promoting. At present, sesame cultivation mainly adopts the "double-stem cultivation method". This method mainly involves removing the growing tip when the third pair of true leaves of the sesame seedling is half-unfolded, so that the axillary buds of the first (or second) pair of true leaves

New black sesame variety successfully cultivated in Hebei
Recently, a new black sesame variety, "dual-purpose oil and food Jiheizhi No. 1," the black sesame variety with the highest oil content in China, successfully cultivated by the Hebei Provincial Institute of Cereal and Oil Crops, passed provincial appraisal. This variety combines high quality, high yield, and disease resistance, and effectively resolves the contradictions between high yield and high quality, and between high yield and disease resistance in black sesame.

Detailed introduction to the sesame variety Hangzhi No. 1
Sesame is one of the main oilseed crops in China and a traditional specialty agricultural product. In recent years, the national sesame planting area has been 13-15 million mu, with a total output of about 1 million tons, ranking first in the world in both planting area and total output. Henan, Anhui, Hubei, and Jiangxi are the main sesame-producing provinces, with the total area of the four provinces accounting for more than 60% of the national total. Jiangsu, Hebei, Shaanxi, Shanxi, and other provinces also have a certain area, with a relatively wide distribution range. Sesame has two cross-provincial concentrated production areas: one is in northwestern Hubei and southwestern Henan,

Hangzhi No.1, a new sesame variety, is the only variety in China developed through spaceflight technology.
Variety origin: "Hangzhi No.1" originated from the key project "Ninth Five-Year Plan Crop Spaceflight Technology Breeding" supported by the Ministry of Agriculture. In 1996, parent sesame seeds provided by the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences were carried aboard China's 17th recoverable satellite, stayed in space for 15 days and then returned to Earth. Since 1997, continuous multi-year ground selection was carried out. Through comparative trials on genetic stability, yield, quality and resistance, it was significantly superior to the control. From 2001 to 2002, it was advanced to the national sesame

How to prevent and control sesame diseases in hot and humid weather
Recently, some farmers have reported that some sesame plants show leaves curling upward and wilting, some report that sesame leaves wilt rapidly from the top downward, and others report that sesame leaves wither from the bottom upward. What diseases are these exactly? The farmers cannot figure it out either, and they are all asking agricultural technicians for technical guidance, telling them how to prevent and control these diseases. From the current climate factors, high temperatures accompanied by humidity easily trigger sesame diseases, especially in sesame fields with poor drainage, low-lying terrain, or continuous cropping, which are more susceptible to disease. From the sesame symptoms reported by farmers in various places
