By the middle of west han, there has been a proliferation of fruit and vegetables. The story is described as follows: “anse mau, qin, qin, qianjiang, qianxi, qianxi, zhui, zhui, zhiru, ziru, zikawa, zilong, zilong, zilong, zilong, zilong, zi, zi, zilong, zi, zi, zi, zi, zi, zi. The abundance of fruit and vegetables production has led to very high revenues from the fruit industry, and has even prompted the court to set up a special “orange” “shaming” for the management and taxation of fruit and vegetables. A number of agricultural, historical and other books written at the time, such as the sijing monograph, the book of the winnings, and the four people's order, documented the variety and name of fruit and vegetables cultivated at the time. There are more than a dozen varieties of fruit, including pears, dates, peaches, plumes, almonds, plumes, grapes, twigs and dynasty eyes; and dozens of vegetables, such as melons, guacamole, tara, sunflowers, mustards, onions, onions, gingers, onions, twigs, and beaks. Moreover, in the practice of growing fruit and vegetables over a long period of time, the population has gradually accumulated a wealth of sophisticated farming techniques and experiences。
I. Time for fruit and vegetable cultivation
In long-standing production practices, there is a growing realization that fruit and vegetable cultivation must follow its own growth habits. Efforts have been made to summarize the habits of these crops and to explore patterns. The book of the winners says, "if you have a plow, it's fun." that is, farming should take place at an appropriate time. Choi choi has documented in greater detail in the four people's order that the month is about to clear the dead leaves in the twilight, and that spring wheat, beans, soybeans, mussels, etc. Can be grown in february。
Early or late planting of fruit and vegetables can have a negative impact. Choi choi choi choi choi choi choi choi choi choi choi choi choi there is no end except for him who is a tree of fruit. The hope is 15 days, and then 15 days, is small.” this means that during the month, trees other than fruit trees are readily transplanted; only fruit trees, preferably in the first 1 to 15. After the 15th of the month, it is easy to have fewer fruit trees。
The handais not only have precise knowledge and requirements about the timing of the planting of the various fruits and vegetables, but also about the planting, irrigation, consolidation and harvesting of the fruits and vegetables. The book of the winners uses almonds as a guide to farming: “almonds are rich, tend to grow light and weak. Apricot drops, tillage.” the rise of almonds is used as a time indicator for farming the soil。

Technology for fruit and vegetable cultivation
Perhaps in the minds of many of us, the handai fruit- and vegetable-planting technology is primitively backward, but it is simply burying seeds of fruit- and fruit-bearing in the soil, during which time water, fertilizer, weeding and then harvest. With regard to indoctrination, greenhouse cultivation and the transplantation of these modern high-tech technologies, how could handai, more than 2,000 years ago, have had them? In fact, we underestimate the ancients, and these technologies are not modern high-tech. The handais are already playing very well。
Bridging is a planting technique that combines two or more different parts of the plant into a whole and can continue to grow. In qinhan, it is very likely that people will be inspired by the phenomenon of twigs in nature, some of which heal and grow together after the erosion of plants under the natural environment, with their branches and troughs. The book of the winners details a marriage method that we call today a “crystal” to produce large guacamole: “ten gills, which grow by more than two feet, gather together in one place to entangle, five inches, and repeat the mud. But for a few days, the entanglement will become one, the strong will remain, and the rest will be strangled, and the chicken will be drawn.”
In many post-50, 60, 70 memories, the vegetables that are eaten every winter are cabbage, carrots, potatoes. Until the 1980s, every winter, unit purchases were made, household cellars containing cabbage were common. Later, with the expansion of the technology in the big sheds, the winter table was no longer a monolithic cabbage, scavengers, stews, and a variety of “anti-season vegetables” such as cucumbers, tomatoes, soybean bean horns, among others, enriched our winter recipes. In fact, greenhouse-planting techniques that create an environment-friendly plant growth through heating in closed spaces have been largely shaped in handy。
West han's wideness was documented in the salt iron theory, when the rich had access to the `winter-homber beryllium'. The so-called warm beryllium is the beryllium that is grown with thermal technology. In the han book, east han bang has detailed the methods of planting vegetables in the greenhouses during the winter: “the tyrannical garden breeds the onions of onions, leaves the house, sets fire day and night, and waits for warmth.” at that time, there were criticisms of the technique of “breaching” the natural growth patterns of crops: “what happens when it comes to new tastes, how many are different, or when it is strong, or when it is ripe to wear it?”
For almost 20 to 30 years, the fruit produced in the spring-south region, such as twigs, dragon eyes and mangoes, has no longer been an enviable fruit for the north, but, like fruit such as apples and peaches, has entered the basket of thousands of families. When you're in the mouthful of the twigs, you're reminded of tang's order to drive all the way, to deliver the story of the fresh twigs to the princess of yang, and of the poems of du sheng, “when the red dust is laughing, no one knows that the twigs are coming”, and soo's twigs, “300 twigs of the day, no matter how long it takes to be a kinnan.”。
In fact, as far back as handy, the qingnan area was ordered to enter the court of the court of the kingdom of the kingdom of the kingdom of the kingdom of the kingdom of the kingdom of the kingdom of the kingdom of the united kingdom of great britain and northern ireland, the kingdom of the united kingdom of great britain and northern ireland. As a result, many trials of transplantation of southern fruit trees to the north were initiated and, despite repeated failures, people were not discouraged by “still year after year”. It has been documented that many southern fruit trees, such as citrus, gills, dragon eyes and bananas, are planted in the forest in the royal west hannese home forest: “so, in luangsha, yellow oranges, gills ... In the hare, in the north garden”. The construction of the “handling palace” in chang an, after han muiti had destroyed south vietnam, attempted to transplant a large number of southern fruit trees, but ultimately failed。
Iii. Fertilizing irrigation techniques for fruit and vegetables
In secondary school history books, people invented iron farming tools, cattle farming and man or animal manure fertilization techniques. How did the handyman fertilize the land? Spreading manure into the ground and mixing it with the soil are perhaps the main methods of fertilization for many farmers. The book of winners also documents the application of manure in the field, which is used mainly for crops such as platinum, taro and platinum. But it's not the only way for handy to fertilize. The book also documents the precise and concentrated application of manure, which is mainly used in vegetable cultivation and in the promotion of the “district planting” method, which is about to pile around seeds. This increases the fertility of the soil surrounding the seeds, provides them with continuous nutritional support and avoids unnecessary waste caused by the application of the field。
When it comes to the way in which the land is irrigated in handy, perhaps many readers will wonder: is it not by digging ditches between water sources and agricultural fields and bringing water into the fields? Although this is a land irrigation method, which is more common in the modern era, it is not the only way to irrigate the land。
In the book of winning, the number of irrigations and the amount of water used for various crops are detailed, perhaps on the basis of the oil-priced nature of much of the north. In particular, he proposed an underground irrigation method, which would bury a three-strength-sized balconium in the middle of four melon seedlings, with its mouth equal to the ground, filling it with water and then covering it with it. The pottery is thick, and water can slowly and continuously penetrate through the walls, providing moisture to the seedlings. When water is scarce, it is added and it is kept full. Such irrigation can provide a balanced and sustained water supply for crops while reducing evaporation on the ground. It can also save water and increase water utilization, especially in the dry and low-water northern regions. This irrigation approach goes hand in hand with water-saving irrigation technologies such as irrigation, which we are promoting today。

Wen shijun said
On the basis of the legacy of past farming practices, the handai people have continued to develop and explore techniques and methods for the production of fruit and vegetables in long-term production practices. Through long-term observation and practice, they have created technologies and methods that are not inferior to today's, in the fields of fruit and vegetable cultivation, including matrimony, greenhouse culture, alien transplantation, fertilization and irrigation, which fully reflect the spirit of thought, exploration and innovation of the handai people。
