At the moment, the news service (journalist gum) in the beijing plains is now in the process of picking up baby food from the field. From the beijing agricultural technology promotion station, journalists learned that field-planting of late autumn pick-up dolls can be sold at the wrong peaks, both to address the low market prices of the fall and to meet the winter spring market supply and to generate more revenue for farmers and farmers。

They are smaller in size than large cabbage, are easy to eat and are becoming more and more popular with consumers. Added to this is the long-term short-term availability of dolls, the low risk of planting, the low cost of management, the low cost of production and the high efficiency of cultivation, which are increasingly favoured by producers。
At the end of october and the beginning of november each year, individual years can run until mid-november, during which the harvest period for the field winters of the beijing plains is judged on the basis of minimum temperature and protection from cold. However, the small size of the doll's vegetables and the reduced commerciality of the leaves following the loss of water demand for storage technology。
Sound post-fall management techniques for doll food are important for reducing the rate of loss and loss, extending the supply period and increasing the efficiency of cultivation. To this end, the beijing city agrotechnical expert has recommended that the criteria for the collection of doll foods are not stringent and are determined primarily by the purpose for which they are collected, and that they can be collected at least ten times as soon as they are sold directly. The storage of doll foods should be delayed appropriately to avoid problems of maturity and poor storage. After the rain and snowfall, dolls are perishable and producers should focus on changes in temperature between late october and early november and collect at the most appropriate time。
Agricultural technology experts recommended that water be stopped 8-10 days before harvest to increase the sustainability of doll vegetables. Before harvesting, if mild cooling occurs, it can be collected when the temperature rises back and leaves return to normal. (c) unsatisfied harvest standards, less mature doll foods, creating the conditions necessary for growth in fields or storage sites to be marketed when product requirements are met. The maturity of the cropping of dolls affects the effects of storage, usually with eight or nine degrees of maturity. They are short-lived and should be suitable for planting depending on their use and the birth of their species. The storage of the food must be delayed by about one week, and the harvest must be delayed in a moderate manner。
The pre-positioning of doll foods involves drying, sorting and pre-storage, but to be effective, it should start with the selection of planting varieties and focus on basic work. Agricultural experts have suggested that 10% maturity is achieved in low-lying, flood-prone plots, with hot hearts, bacterial spots, white-haired dolls that are not suitable for storage; it is best to store 8 or 9 maturitys, no heart, no pests, green leaves, yellow inner leaves. At the time of harvest, there is a high amount of water in the doll's vegetables, which should be dried up in the fields, softening the tissue after the loss of some of the water on the outer leaves and improving its ability to withstand the cold, but not excessive water loss due to the small size of the individual. The bulk of the sorting is the removal of rotten leaves, sick leaves and yellow gangs, which generally do not remove whole pest-free leaves. The pre-storage process involves the timely storage of modified doll foods at temperatures of 1-2°c; the pre-storage chain needs to prevent heat and coldness。

In storage, attention is paid to the temperature and humidity of the storage of doll foods, which are suitable for storage at 0°c, 95% humidity, 1 - 6% oxygen concentration, 0 - 5% carbon dioxide concentration, and storage methods such as falsification, storage, ditches, cellars, cold storage, air conditioning. Agricultural technology experts indicated that the storage of gas reservoirs is long and has the best effect, but that storage costs are high and, when conditions permit, the storage of gas reservoirs can be used. They are stored in a variety of ways, but they are more recommended in the form of idle plastic sheds for the winter, which are simple and easy to grasp, and which contain quantities that are small, low-cost, low-loss and cost-effective. However, for late-planting and less mature pick-ups of doll foods, such as fake planting can be used to keep them growing and then sell them after meeting standards。

In addition, new leaves should be seen before the dolls are sold, and commercial requirements should be met, with the weight of the three trees normally being 500 grams. Appropriate packaging should be selected according to the distribution channels and distribution methods. They are packed in a simple manner, consisting mainly of flavoured membranes, packaging boxes, bags, etc. They are best protected with a permeable 0. 01 mm thickness of pepo, which avoids mechanical damage and prevents the atrophy of the doll's food and preserves its impurity。
Beijing agrotechnical experts have recommended that the dolls that citizens buy home are suitable for storage in their home refrigerators, because of their high water content and their preservation, their loss of water from their outer leaves, their loss of flaccidness, their increased humidity, their use of wrapping paper, which absorbs part of the water, both to maintain humidity and to avoid decay, and the fact that they are free of surplus leaves, which make it easier for families to buy them。
