Key Technical Points for Field-Stage Management of Machine-Transplanted Rice
Machine-transplanted rice, due to constraints such as seedling age, nursery age, sowing date and plant traits, has relatively high requirements for the tillage and preparation quality of the transplanting field. At the same time, machine transplanting achieves wide-row, fixed-hole, fixed-seedling and fixed-depth planting, satisfying the population basis for high-yield rice population-quality cultivation. Therefore, only by grasping field-stage management of machine-transplanted rice without letting up can we ensure early tillering and steady growth after transplanting, strive for sufficient panicles, promote large panicles and achieve high yields. 1. Field preparation: 1. Fine land preparation: Field tillage and preparation should adopt rotary tillage for stubble removal, with a rotary tillage depth of about 12-15 cm. After introducing water, wait until the water is fully absorbed before

Detailed Explanation of Key Points of Fertilization Technology for Machine-Transplanted Rice
The total amount of fertilizer applied to machine-transplanted rice is roughly equivalent to that for manually transplanted rice. However, how it is applied at each stage differs between machine-transplanted rice and ordinary hand-transplanted rice. The main reason is that machine-transplanted rice has lower tillering node positions and a longer tillering period. To keep the number of panicles in the population within an appropriate range, the focus of fertilizer management should be on improving the timing of tillering fertilizer application, so as to regulate and utilize the optimum tillering node positions and control the mid-season population, while increasing the application of panicle fertilizer to promote spikelet differentiation and strive for large panicles. The characteristics of machine-transplanted rice and hand-transplanted rice determine that among the basal and tillering fertilizers for machine-transplanted rice, the basal

Key Cultivation Techniques for Machine-Transplanted Rice at the Transplanting Stage
I. Make a Good Start and Manage the Seedling Nursery Well 1. Apply the "standing-up fertilizer" according to seedling appearance. This is generally done 3-4 days before transplanting; the amount and method of application should depend on seedling color. For weak seedlings with faded leaf color, use 4-4.5 kg of urea per mu diluted in 200 kg of water, and spray or splash evenly in the evening; after application, sprinkle clean water once to prevent fertilizer burn to the seedlings. For seedlings with normal leaf color and upright leaves that do not droop, use 1-1.5 kg of urea per mu diluted in 60-70 kg of water for foliar spraying. For seedlings with dark green leaves and drooping leaves, do not apply fertilizer at all; water control measures should be taken to improve seedling quality.

Detailed Explanation of Key Techniques for Raising Strong Seedlings for Machine-Transplanted Rice
With the improvement of the level of intensification in rice production, mechanical transplanting has become an inevitable trend. One of the keys to machine-transplanted rice production is raising strong seedlings. The following measures can produce strong seedlings: 1. Apply strong seedling agent. The strong seedling agent is usually mixed with the subsoil. First mix a small amount of fine soil with the strong seedling agent evenly, scatter it on the bottom of the seedling tray, and then add the subsoil. This avoids uneven mixing and scattering due to too much subsoil, which leads to uneven distribution of the strong seedling agent, causing seedling dwarfing and failure to emerge where too much strong seedling agent is present, resulting in seedlings pulling loose during transplanting and affecting the quality of mechanical transplanting. 2. Cover with plastic film.

Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing
Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control

Introduction to the Features of the Dry Garlic Peeling Machine
1. It adopts a specially designed peeling principle. During the peeling process, the garlic cloves do not pass through blades or undergo hard friction at all, so the integrity, freshness and freedom from contamination of the processed product are ensured. 2. It features automated continuous operation of drying and peeling, and is practical, power-saving, small in size, high in production efficiency, easy to maintain and clean, and low in failure rate. 3. It is equipped with automatic temperature control and automatic feeding devices, and the garlic kernels and skins are separated automatically. The product meets hygiene standards, and because the garlic kernels are not easily damaged, they can be stored for many days, which is an advantage.

A Complete Analysis of the New Machine-Bagging and Irrigation Technology for Oyster Mushroom Cultivation
Drawing on shiitake mushroom production techniques to grow oyster mushrooms, a new machine-bagging and bag-cultivation technology for oyster mushrooms has been summarized, and it is introduced as follows: 1. Preparation of spawn bags: according to the formula of 88% cottonseed hulls, 10% wheat bran, and 2% gypsum, add 1.1-1.2 kg of water per kg of dry material. Use the special bagging machine for shiitake production to fill the material into 55×15×0.004 cm low-pressure polyethylene plastic bags, with each bag holding 2.1-2.3 kg wet weight of material. Then, put the material bags into a sterilization stove for sterilization; after the temperature rises to 100°C, keep it for 10

How is the TP stainless steel garlic peeling machine?
Before using the machine, the garlic roots must first be removed (if the roots are not removed, the time will be longer), and the de-rooted garlic should be soaked in water. When peeling, pour about 30 kg of garlic into the machine at one time; after it runs for about 5 minutes, open the discharge outlet and the garlic cloves will come out on their own. After the garlic cloves have been fully discharged, close the discharge outlet, then repeat the above process and pour the garlic into the machine. The feature of this machine is that it has the function of breaking apart garlic bulbs and can be used continuously without stopping. If it is not peeled clean the first time, it can be put through the machine a second time to peel it clean.
