What are the key technical points for field tillage and preparation for machine-transplanted rice?
For machine-transplanted rice fields, different tillage and preparation methods should be adopted according to the cropping sequence, soil characteristics and other conditions, and base fertilizer should be applied according to local conditions based on soil fertility. Tillage and preparation of fields following a previous crop: 1. Crushing the straw of the previous crop. When the previous crop is harvested, the straw must be crushed and evenly spread. If crushing was not carried out during mechanical harvesting, an additional straw-crushing operation should be added or the straw should be removed from the field. 2. Dry tillage. Under suitable soil moisture and water content conditions, three methods can be used to kill stubble: forward (reverse) rotary tillage, shallow plowing and harrowing of stubble, among which the reverse rotary stubble-killing method

Key Technical Points for Cultivating Strong Seedlings in Rice Tray Nursing for Machine Transplanting
Economic Daily News: Raising small strong seedlings of tray-nursed machine-transplanted rice is an important part of achieving high quality and high yield in machine-transplanted rice. The specific technical points are introduced as follows: Tray soil preparation: select loam soil that is fertile, free of stubble, gravel, weeds, and free of contamination to seedlings, with a pH value of 4.5-5.5. If such acidic soil is not available, sulfuric acid or nitro humic acid can be used to adjust the acidity. To prevent damping-off and other seedling-stage diseases, apply 50-60 grams of dexon per cubic meter of tray soil. To fertilize the tray soil, add pure nitrogen, pure phosphorus,

What are the advantages of machine-sown rice? A detailed guide to the supporting cultivation techniques
Common rice transplanting methods include washed-field transplanting, machine transplanting, and seedling throwing. Based on the growth and development patterns of rice and the soil and climate characteristics of Hunan, we developed the "Shuhua 2BR-100 and 2BD-150 rice seeders" (patents already applied for). Using machine-sown rice and integrating practical high-yield techniques such as ridge cultivation, mud-paste valley covering, furrow opening, and single-grain shallow sowing, we solved the difficulties of achieving full stands, uniform seedlings, strong seedlings, and no seedling rot in a single sowing of rice; we fully tapped the tillering potential of rice, giving individuals good development

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
