The period from the end of effective tillering to the beginning of panicle initiation is the most drought-tolerant period of rice. Production practices have proved that moderately-baked field can effectively promote the development of seedling root system and increase nutrient absorption, which is an important part of vegetative growth and reproductive growth. This area belongs to the main rice planting area, and through the paddy field of some rice fields, it has a good effect of rooting, disease prevention, lodging resistance, early maturity, and yield increase. The rice spike rate in the field is 67.5%, and the output of 667 square meters is 678 kilograms, the rice spike rate of unroasted field was 53%, and the output of 667 square meters was 639 kilograms.
First, the role of baking
1. Effective control of invalid tillers, so that the seedlings enter a stable long, in order to ensure adequate supply of nutrients for the main stem and early tillers, and increase the effective ear spike rate.
2. To create good conditions for the application of panicle fertilizer, dwarf strong stalks to attack large spikes.
3. Enhance the permeability of soil, speed up the decomposition of organic fertilizers, reduce the hazards of acid substances produced under the action of black roots and anaerobic bacteria, enhance the absorption capacity of roots, and expand the nutritional area.
4. Make the plant stalk thick, control the height of the plant and enhance the lodging resistance.
5. Reduce the humidity in the field, improve the ventilation and light transmission conditions, enhance the photosynthesis of the leaves, and reduce the incidence of blight and rice blast.
6. Weeding the weeds, reducing ground consumption, saving water, and reducing production costs.
Second, the practice method of baking field Practice has proved: to ensure that early-maturing varieties of 667 square meters produce 450 kg, 670 square meters of late-maturing varieties produced more than 600 kg, based on two: First, the number of seedlings, early maturity of 700,000 square meters need 700,000 square meters The basic panicles, medium-mature varieties of large panicles reached 750,000, late-maturing varieties of dwarfs reached 75 to 800,000, and effective tillers were calculated at 65%. The second is the time, about 50 days after emergence of early-maturing varieties of early water, about 60 days of medium-maturing varieties, and about 70 days of late-maturing varieties (we should subtract the number of days of breeding during transplanting). The number of seedlings is sufficient, but when the time is not up or the number of seedlings is not enough, the high-yield rice fields should be baked. However, due to the time, place, and seedlings, falling into the water, the field must not be cut. The plants are growing vigorously, the density is too high, the leaves are covered with dark green, the premature seal line should be properly sun-dried and re-sunshine; otherwise, the sun exposure and light-sweetness should be used; the number of seedlings that reach or exceed the planned index should reach early sun; the soil quality is poor, Sandy, light and light can be light or no sun. Alkali large rice fields do not sun or light sun; field hard sun; people walk footprints re-sun; people take no footprints, but the soil can not be white, leaf color from dark green to yellow green to achieve this standard immediately shallow water, wait until After it is dry, it maintains shallow water and strong stalk jointing. After the “jointing stage†is presented, the young ear-differentiated fertilizer is timely and properly chased to make the leaf color turn green in time, so as to promote the vigorous stalks to attack the big spikes and achieve large spikes, multiple ears, and grains. Large, full grain, achieve high yield.
