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 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

How can straw return to the field be made more efficient? Agricultural machinery operations need more effort
In 2015, the central government allocated 800 million yuan to support and encourage the promotion of soil improvement techniques and increase soil organic matter content, among which the comprehensive promotion of integrated straw return technology is one of the main uses of this funding. Pan Wenbo, deputy director of the Planting Industry Department of the Ministry of Agriculture, told reporters
