When applying planting techniques and fertilization techniques, rice planters must rationally apply various technical methods to improve the yield and quality of rice planting, improve the economic benefits of planting, reduce the various types of losses, and enhance the reliability of rice planting.
Here are some important questions that exist in the rice planting process of farmers:
1. How to weed the rice?
Add 2,4-D butyl ester to the paddy field to make the grass roots rot, and the second year will be less. The dosage of 2,4-D butyl ester should not be excessive. It should not exceed 7 yuan per mu of land. It is about half or so. It should be as much water as possible. The effect of water is better. The more water, the more uniform the medicine is. Before the rice is packaged, it will not be late until June 25th - July 5th. After the late rice, the grain of the rice is prone to stage white matter, and then it does not form. 2,4-D butyl ester is more important, the rice ear is smaller, the rice is not agglomerated, and the rice plant is curved.
2. Can the diphtheria and herbicides be used together?
The time of administration is not the same, and the mechanism of action is different. The herbicide is mainly applied to the rice straw to let the insect die. The herbicide is applied to the rice straw and applied to the grass. It is completely two ways. Try not to Play together. Do not use excessive amounts of pesticides in rice, use a large amount of insecticides in rice at the seedling stage, and produce phytotoxicity in rice, which can be deformed and the leaves are snoring.
3. Can you take the enemy with an insecticide?
Take the enemy stability itself is a fungicide, insecticide can be mixed, but in the early stage must add more water, the amount of water will produce a lot of red spots.
4. Does the rice see the ear and fight drugs?
Seeing that the ear is just blooming, the rice flowering time is about 9:00 to 12:00 in the morning. Generally, the temperature is required to be at least 23 degrees above the bottom, 27-28 degrees before the flowering. The more the humidity, the more flowers, everyone may have experience, sauna days, rainy days. When the weather is particularly hot, the flowers bloom very fast, and the windy days and cool days are slow. If the insecticide or any medicine is used during the flowering period, the dose is normal, the concentration is too large, and the effect is strong. It is better to fight drugs after 2 o'clock.
5. How to fight rice blast drugs? Can't you fight in the morning?
Rice blast medicine is a fungicide, it is best to fight in the evening. It is best to play early in the early stage of the booting. In the rupture period, it is the 1% of the rice that sees the ear. At this time, the second one is the fresh-eared spike. , catch the afternoon, because this time rice blossoms affect the flowering.
No in the morning, playing in the afternoon, it is best to play in the evening.
6. Is the water in the low temperature weather better or less water?
From the perspective of low temperature, how good the water is, and the low temperature resistance, from the anti-falling, it is better to see how the water can not fall.
If you are afraid of falling, you should drain the water, let the mud dry, and fix the roots. When it is dry for a few days, you need to replenish water. Appropriate late water cut, rice is delicious, rice is high, rice can live mature stalks, water cuts are not good, water breaks early, rice is prone to premature aging, rice is not shiny, rice grains are falling, that is, late water is better than early water. It is recommended that the water should be cut as soon as possible before cutting the ground.
7. Why is the rice ear wilting?
The water spikes withered and the dead grass see two factors. The first one looks at the bottom of the stalk with no insects or insects. The second one is to see if there is any smear and bruises. The third is to look at Ke Wei. When there are a lot of cockroaches, the nutrients can’t keep up. It should be degraded, and it can’t compete with the light, the wind, the air. When the nitrogen oxides and the light are not enough, they starve to death and turn yellow. The original Ke Wei was originally 20, and the result was 30. It was going to starve.
8. How long is rice growing taller?
Looking at it now, the fertilizer is large, the rice stalk is normally 1.1, causing 1.2-1.3 m high. As soon as possible, drain the sun and fix the roots. Because this year's wind is big all year round, don't fall.
Where the rice is fat, because the rice stalk is high, the leaves become longer, the ears become smaller, and the mites are also more. When the fertilizer is big, the plant type changes, just like a scorpion, normal 150 kg. It will grow to 200 pounds. If you don’t see relatives for a year, you won’t know you. It’s all unchanging. His body, the genetics given by his parents is just 1 meter. You make it 1.2 meters long, long variant, what should I do? Drain the sun, and conditionally hurry up the potassium dihydrogen phosphate to strengthen the stalk to prevent lodging.
9. What proportion of the late potash fertilizer is appropriate?
The potash fertilizer alone can be raised by 70% in the early stage and 30% in the early stage of the jointing stage or at the end of June.
But now that the technology is advanced, the phosphorus and potassium are mixed together and the whole process is raised. It is early because the potassium fertilizer is not lost.
The normal method of lifting fertilizer must be closed before the fertilizer is lifted. When the fat is finished, when the water seeps out, when there is no water, then the water is supplied, and let it flow.
10. What should I do if the rice is greedy?
Greedy, come to the rice gold foliar fertilizer, it contains 12 kinds of elements, you can also add less potassium dihydrogen phosphate, all kinds of elements are fully developed and will develop faster.
11. How much is the amount of potassium dihydrogen phosphate?
Potassium dihydrogen phosphate is a fully soluble phosphate fertilizer and potassium fertilizer. It is the best phosphate fertilizer and potassium fertilizer. It is fully soluble in rice fields and is bagged. Generally 1 / 500 concentration can be (500 kg of water plus a catty), if you hit 1 / 100, there will be too high concentration of leaves burned into red spots.
12. How to use rice fertilizer?
Rice is best used for soil testing and fertilization. The normal amount of nitrogen fertilizer does not exceed 350 pure nitrogen, but if you chase the special fertilizer for rice, you should pay more for the later rice. Because of the balanced absorption of nitrogen, phosphorus and potassium, it is also a disease to catch up late, because the key to planting rice depends on the last fat. If you chase more, then it will come to the disease, rather than a lot, rather than giving. If you use rice special fertilizer, it has potassium fertilizer all the way, you do not need to chase potassium fertilizer.
You have to mix fertilizers with blended fertilizers and mix all kinds of fertilizers. Now it is not feasible to look at rice. It is quite good to mix diamine, potassium fertilizer and urea. However, the diamine is 5 meters away, the urea is 3 meters away, and the potash is not raised. It is naturally separated. Like the rural field, the rice and the grain are separated, so the blended fertilizer does not work in rice. . Including corn in the future must be granulated, it is uneven in the funnel, melting weight, weight is not the same, naturally separated, fertilizers to promote granulation of compound fertilizer.
