After the early rice machine inserted early tube

At present, the early-season rice transplant in Dingcheng District has already passed halfway. It has been plugged in for a week and is already alive. After the early rice transplanting, it needs early management to promote early living and early delivery, and build good seedlings. Mainly grasp the following four aspects of management:

One is to make up for the shortage in time. During the three days after the early rice transplanting, the seedlings must be timely replanted around the plots and the leakage plugs to ensure that the basic seedlings are planted.

The second is to manage Tian Shui. Machine-planted seedlings are small, heavy-planted, and long-lasting. Water management is based on the principles of “light” and “dilute”. Thin-water rice transplanter (water depth 1-2 cm), during the period of seedling planting seedlings, during the period of planting seedlings in the case of good weather, irrigation of shallow water protection seedlings (depth 2-3 cm), timely drainage in the event of rain; after the seedlings live, shallow water diligence Irrigation, appropriate exposure to fields, the implementation of alternating shallow wet and dry irrigation.

The third is to chase after manure. Used for transplanting seedlings is relatively small, the ability of sucking fertilizer is poor, the tiller fertilizer can not be applied too much too much, otherwise it is easy to produce fertilizer. The early rice tiller fertilizer is generally applied in two batches. The first time after transplanting about 5 days, the urea topdressing 3-5 kg ​​per acre, followed by a second time after 10 days, applying 5-8 kg of urea per acre plus potassium fertilizer 7-8 Kilograms (or 15-20 kilograms of high-content compound fertilizer) promote early delivery and more labor.

The fourth is chemical weeding. In the first 7 days after transplanting, the first application of seedling herbicide (such as benzyl benzothiazolyl) is applied in combination with fertilizer, and the water is preserved for more than 3 days after the application of the herbicide. Do not flood the heart of the seedling.
