Abolishing the agricultural household registration: these eight points must be clearly understood
Land cannot be privatized; without it, China's rural problems cannot be solved. We must also strive for equal legal treatment of the agricultural population after they move to the cities. First, abolishing peasant status is the starting point for other subsequent reforms. Without the legally defined differences in national identity, other

What to Do About Premature Senescence in Greenhouse Vegetables? 7 Prevention Tips Worth Saving for Vegetable Growers
The rise of greenhouse vegetables lets consumers enjoy many off-season vegetables and allows vegetable growers to boost their economic returns, but if greenhouse vegetables are not managed properly in the mid-to-late growth stage, premature senescence often occurs, reducing yield and lowering quality. So what should be done about premature senescence in greenhouse vegetables? These 7 tips work best when used early, and vegetable growers are advised to save them.

Winter Greenhouse Three-Film Potato Planting Technique: High Yield, Early Market, Good Returns
Abstract Greenhouse construction: choose a plot with loose soil for building the large arch greenhouse and small arch greenhouses. Plowing and fertilizing: carry out deep plowing and apply fertilizer rationally before planting. Variety: early-maturing varieties with a short dormancy period should be selected. Seed selection and soaking: it is advisable to choose small potatoes or cut pieces of large potatoes, soak and sprout them before sowing, and plant once young sprouts have grown. Sowing: in late December, plant about 5000 plants per mu and complete the three-film covering. Field management: pay attention to temperature and humidity, fertilizing, watering and pest and disease control.

What to Do About Hollow Heart in Radishes? Causes and Control Measures in Early Spring
Radish hollow heart, also known as pithiness, is the phenomenon in which a cavity forms in the central part of the xylem of the fleshy root. 1. Causes: (1) Related to variety. Varieties with large parenchyma cells in the fleshy root have poor root density and are prone to hollow heart. (2) Related to soil texture. Radishes grown in soil with excessive sand tend to develop hollow heart earlier than those grown in loam or clay. (3) Improper water supply. If moisture is even during the early growth period but drought occurs later, especially during the fleshy root formation stage, soil water shortage hinders growth, resulting in hollow heart. (4) Unreasonable planting density. Under wider plant and row spacing, the fleshy root grows too quickly, and the growth of leaves and roots loses balance, so the organic nutrients produced above ground are insufficient to supply the needs of the expanding fleshy root below ground, making hollow heart likely. (5) Unreasonable fertilization. Especially when topdressing is too late and too heavy in the later stage, combined with improper matching of fertilizer types, applying too much nitrogen fertilizer makes the above-ground part of the radish grow too vigorously and the root becomes excessively large, causing hollow heart. (6) Harvesting too late or bolting having already occurred. (7) Wounds such as cracked skin and cracks caused during harvest, storage and transport increase respiration and cause excessive nutrient consumption, leading to hollow heart. (8) Storage temperature too high. The suitable storage temperature for radishes is 1-3 degrees; above 3 degrees they readily sprout and grow, leading to hollow heart. (9) Storage environment too dry. The ideal air humidity is 90-95%; when it is below 90%, radishes continuously lose water, making the tissues soft and causing hollow heart. 2. Control measures: (1) Choose varieties that are not prone to hollow heart and have a high degree of fleshy root density. (2) Plant at a reasonable density. (3) Fertilize scientifically. For spring radish fertilization, adopt the principle of giving priority to base fertilizer and supplementing with topdressing, and pay attention to the rational combination of the three elements nitrogen, phosphorus and potassium. (4) Supply water evenly. Prevent the soil from being too dry or too wet, and maintain soil moisture at 70%-80%, especially in the later growth stage of radishes, when the soil must not be too dry. (5) Harvest at the right time. (6) Chemical control: generally half a month before harvest, spray once with a 50mg/kg gibberellin solution (do not spray too early, to avoid inhibiting fleshy root expansion), or spray once with a 10mg/kg naphthaleneacetic acid solution, which neither affects fleshy root growth nor prevents hollow heart, and delays maturity. If when spraying 10mg/kg naphthaleneacetic acid, 5% sucrose and 5mg/kg borax solution are added and the three are mixed and sprayed, the effect of preventing hollow heart is even better. (7) Minimize mechanical damage such as broken skin and breakage during harvest and transport. (8) Pay attention to the temperature and humidity of temporary storage.

Key Points of Early-Maturing Cultivation Techniques for Eggplant in Greenhouses
Eggplant, also known as qie, with the alternative name luosu, is one of the few purple vegetables and is also a very common home-cooked vegetable on the dining table. In some areas of Jiangsu, Zhejiang and Anhui it is called luosu, while in Guangdong and Guangxi it is called aigua.
