Rice planting techniques and field management techniques are as follows:
First, pay attention to the quality of rice transplanting.
When transplanting seedlings, we should pay attention to the quality of transplanting, pull the line to transplant seedlings, straighten the holes evenly, do not lack holes and do not drift seedlings, and the depth of transplanting is 2 cm. When the paddy field is 1 cm to 2 cm shallow water, the rice field will be flooded immediately after transplanting to protect the seedlings. When the average daily temperature is stable at 13 o'clock, it is the suitable period for transplanting, and the transplanting specifications are 30 cm in rows, 12 13 cm in plant spacing, and 3 4 plants per hole.
The plant is tall and has large spikes and tillers.
Strong varieties, hybrid rice.
2 or 3 plants can be inserted. Mechanical transplanting is recommended to control the number of acres of rice transplanted per day. The transplanting machine needs to control the speed of transplanting to avoid the lack of seedlings.
It is necessary to arrange the time of transplanting rice reasonably, taking into account factors such as weather, damage to the rice transplanter, and pre-repair of vigarine, and the weather is not good, and it is okay to delay it for 1-2 days.
Second, check the field and replenish the seedlings.
When transplanting seedlings synchronously, the seedlings are in place, leaving no dead ends, the end of transplanting, the end of the seedlings, improving the efficiency of the seedlings can also improve the quality of the seedlings, and don't be afraid that the seedlings are not rooted, and the seedlings will be replenished in the later stage. In addition, the remaining seedlings should be removed from the field in time after the seedlings are replenished.
3. Management of the water layer after transplanting.
After transplanting, we must protect the seedling water in time, the seedling is injured when transplanting, the absorption capacity is reduced, and it is very sensitive to water.
Water layer management in the regreening stage: deep water seedling protection after transplanting, water depth seedling 2 3, subject to the non-flooded seedling heart, water to protect the seedlings, water to increase temperature, and promote the rapid return of rice to green.
Closed cultivation management of water layer at tillering stage: shallow irrigation after returning to green and trembling clearing, 3-5 cm water layer, shallow water warming to promote tillering, early growth and rapid onset. Sunlight can directly shine on the stems, increase water temperature and ground temperature, increase soil oxygen content, promote root development, and promote the early occurrence of rice tillering.
Fourth, apply tillering fertilizer in a timely and appropriate manner.
Nitrogen nutrition plays a leading role in rice tillering, and the amount of fertilizer applied at rice tillering stage is 25 30 of the whole growth period, so early application of fast-acting nitrogen tillering fertilizer makes the leaf color turn black quickly, which is the main measure to promote early tillering.
The tillering period of early rice varieties is short, and the tillering fertilizer must be applied once within 7 to 10 days after transplanting. At the end of the effective tillering period, if the effective stem number is significantly less than the expected suitable number of panicles, tillering fertilizer should be applied appropriately to promote the stable growth of tillering.

1. Scientific irrigation. Water is the basic substance to ensure the normal growth of rice and improve rice yield. In order to better manage rice, scientific irrigation should be carried out for rice, and different irrigation dosages and irrigation methods should be selected at different stages of rice growth.
2. Reasonable fertilization. Fertilizer is an important substance to promote the growth of rice, and it is also an important component to promote the increase of rice yield. Therefore, attention should be paid to meeting the demand for fertilizer in rice and rational fertilization.
The amount of rice fertilizer should be determined according to the yield target requirements of rice, and farmhouse fertilizer, 20kg of general calcium and 10 20kg of potassium sulfate fertilizer should be applied to rice before transplanting. After transplanting, urea or other nitrogen fertilizer is used for one-time top dressing.
3. Spray pesticides appropriately. Pesticides can effectively prevent the occurrence of various pests and diseases, which is conducive to the healthy growth of rice. Therefore, in order to scientifically manage rice, it is necessary to spray certain pesticides on rice appropriately, and it is generally best to fertilize pests in the larval stage or at the early stage of disease.

Rice planting technology and field management include seedling raising, transplanting, water and fertilizer management, flood control and drainage, pest control, etc.
1. Seedling. Before rice planting, choose to cultivate seedlings in suitable fields, select full, high-quality seeds, remove shriveled and inferior empty shells, sow seeds by sprinkling, sprinkle a layer of rice husk ash on the surface, cover the rotten manure, and wait for the seedlings to break the shell and grow.
2. Rice transplanting. When the rice seedlings grow 7-8 cm, the seedlings can be transplanted, the seedling field of the transplanting should ensure that the drainage and irrigation water is convenient, the soil layer is fertile, and the plot does not contain saline, and the basal fertilizer is applied to plough the soil and fertilizer evenly 3-5 days before transplanting, and the seedlings are transplanted according to the row spacing of 30x13 cm, and each seedling hole is 3-4 plants.
3. Water and fertilizer management.
Rice seedlings are mainly drought-based before growing 3 leaves, fertilizing with urea and watering a small amount when 2 leaves are one heart, applying tillering fertilizer when growing 3 leaves and one heart, choosing urea or formula fertilizer, watering after fertilization and limb beats, so as not to cause fertilizer damage due to excessive fertilizer concentration, and chemical control when growing too vigorously.
4. Flood control and drainage.
Dredging the "three ditches" to ensure smooth drainage and respond to flood disasters in advance. For flooded fields, drain the open fields as soon as possible to restore the growth vitality of the root system and prevent lodging; Clean water was used to remove mud and debris on rice plants to promote the recovery of leaf function.
5. Pest control.
During the growth period of rice, weeds in the field should be pulled out in time to reduce the excessive consumption of water and fertilizer in the soil, and diseases should be prevented and controlled by fertilization.
Cultivating and weeding: Cultivating and weeding 3 or 4 times a year when peony is first planted, the first time is in spring after the seedlings, it should be shallow; The second time was in the summer when weeds were abundantly grown, which was slightly deeper than the previous time; The third time is in the autumn after the seedlings are poured. >>>More
1. Set up scaffolding and select seeds.
Greenhouse toons should be planted with enough base fertilizer to ensure that the plot is fertile. After fertilization, it is necessary to plough the land once and tidy the furrow, and the width of the furrow surface is 60-100 cm. Toon seeds should be selected with high germination rate, easy to control, and good quality. >>>More
According to the local planting climate conditions and local soil fertility level, varieties with strong stress resistance are selected for planting. Wrap the seeds with gauze and soak them in cold water for about 1 hour, then pick them up and put them at 15 20 °C for 2 days, mix the seeds with a new high-fat film before sowing to drive away underground diseases and insects, and choose new varieties of "double low" or hybrid rapeseed with high quality and high yield, good disease and stress resistance, and wide adaptability, and moderately increase the amount of seeds per mu to ensure the basic seedling and group structure, and seize high yield and stable yield. And every 3 or 4 years, the varieties are constantly updated to maintain the potential of improved varieties to increase yield. >>>More

I'll give you advice, can you see it? 1.Look at the world with another eye, not everyone in this world is very smooth, just look at how you solve it, for example, you were hit by someone when you were walking, others apologized to you, sometimes you still feel very angry, but you didn't expect that the person who hit you was actually more uncomfortable than you, or think about the sentence "Happy is also a day, unhappy is also a day, why not be happy every day". >>>More
