Does the light rain every day affect the rice when it is about to come out of the grain?

In this case, there will be an impact, and relatively speaking, there will be some conditions, then this situation will affect its growth, and it will have an impact on the yield.

Light rain every day has an impact on the rice that is about to emerge from the grain, and the rain will affect the poplar flowers of rice, which can not be pollinated well and will affect the yield.

If it is the time when the rice is out of the grain, it is a light rain every day, and the sun does not come out at all, of course, it will have a great impact on the flowers will be knocked out by the rain, which has a great impact on the rice out of the grain.

Every day, when the light rain arrives at the rice to produce grain, it will generally have a certain impact, because too much humidity is not conducive to its growth.

Every day, the light rain rice is about to come out of the grain, it should still have an impact, and the humid air may affect the millet more easily.

Every day, the light rain rice is about to come out of the valley, there is no effect, as long as there is no deep water, the height of the water can be maintained.

Of course, the light rain every day has an impact on the rice being out of the grain, and the water is poured out when it is five years old, which is the season when the rice is flowering, so the pollen is washed away by the rain. The instructions must not be full, they are all holding back, and they can't live.

Hello, friends rain every day, rice is out of ** has a certain impact, if it rains every day, the weather is not good, the fifth day of the first day will be relatively slow, I hope to help you.

Every day, light rain will have an impact on the rice that is coming out of the grain, at least there are more millet!

There will be an impact on this, and relatively speaking, it will affect its production, so you must pay attention to this aspect, in this case, the impact may be relatively large.

It is a light rain every day, which must have an impact on the rice going abroad, and if it is said that people will rain lightly every day, the blood that grows at that time will not be so full, and the yield will definitely have a certain impact.

With light rain every day, is the rice about to have an initial impact? I think it should have some impact, and I should consult an expert about this.

The daily light rain has an impact on the rice out of the grain, because the rice in this world will oxidize and affect its maturity.

If there is light rain every day, it will indeed have some bad effects on the rice.

Does the daily light rain make a difference when rice is emerging? Every day the light rain rice is going abroad is influential.

Every day there is a light rain, and the rice is coming out of the valley, which must have an impact. The millet will become less full.

Every day there is a light rain, and the rice is going abroad, does it have an impact? Every day, the light rain has an impact on how the underworld came out of the ancients.

Excessive rain will affect the spread of pollen from the sterile line to the stigma of the restorer line, and secondly, the high water content will also lead to a decrease in fertilization rate. In short, it will lead to a decrease in production.

What should I do if the rice is flooded due to excessive rainfall?

In the year of the rainy season, the rice fields with poor drainage are susceptible to waterlogging, and the rice is not only lodging in the case of waterlogging, but also the soil moisture is too large, the aeration is poor, the physiological activities of the ground temperature reduction are greatly affected, and even the tillering dies, and the following remedial measures are proposed:

1. Drain the stagnant water as soon as possible.

Clean up the drainage system in time to reduce waterlogging, if it is cloudy, you can take a one-time drainage, in case of scorching sun and high temperature weather, the upper part of the rice plant should be exposed to the water first, and then drain the stagnant water after 24 hours, so that you can avoid exposure to the sun, which is conducive to restoring growth.

2. Wash seedlings in a timely manner to control water.

After the water recedes, the coarse water is used to spray the sediment and other debris on the rice plant, so that it can restore the physiological functions such as photosynthetic respiration as soon as possible, and the water in the paddy field is still in a saturated state after the water is discharged, and the ditch should be cleaned up, and the dry, dry and wet irrigation method should be adhered to.

3. Apply fast-acting fertilizer.

During the damage period, the rice plant nutrient was damaged to varying degrees, and the original rice field fertilizer loss was more, so the top dressing should be fast, the dosage should be accurate, as far as the tillering period is concerned, within 3 days after drainage, 8 kg of urea per mu plus 5 kg of potassium chloride, 10 kg of special fertilizer for rice in the middle, the amount of light fertilizer used by waterlogging is appropriately reduced, and the opposite is heavier.

4. Comprehensive control of pests and diseases.

The leaves and tillers born after the restoration of the growth of waterlogged rice are tender and green, and they are susceptible to diseases and insects, so attention should be paid to the prevention and control of armyworms and borers, and the control of shover leaf blight and rice blast should be strengthened in the later stage.

Because the specific heat capacity of water is very large, more water is irrigated at night in order to reduce heat loss, and some water is released in the morning because the temperature during the day is higher than that at night, so that the water will not absorb too much heat, so that the temperature can be raised, and the temperature rises, the activity of enzymes in the seedling body increases, the internal chemical reaction rate increases, and the efficiency of photosynthesis is naturally improved.

First, the root and leaf growth of rice seedlings are slow, the growth of seedlings is weak, the transplanting time is delayed than usual, the return to green time after transplanting is prolonged, and the growth process is delayed by about 10 days compared with the normal year in severe cases. Second, rainy weather is easy to make the paddy field water deeper, resulting in soil hypoxia, hindered physiological metabolism of rice roots, decreased vitality, weakened fertilizer absorption ability, slowing down the leaf emergence rate of rice, reducing tillering per plant, and insufficient group growth. Third, excessive rainfall is easy to cause irrigation and drainage, and fertilizer loss leads to insufficient nutrition of rice.

Fourth, there is a lot of rain, which is very beneficial to the epidemic of diseases such as rice blast and the migration of "two migration" pests.

Rain has no effect on the rice that has just been sown in a season, and the rice is originally grown in water, so pay attention to fertilization and drainage.

Oryza sativa (scientific name: oryza sativa) is a type of herbaceous rice, and it is also the most important and longest-standing food in the rice genus. It is an annual, grassyleous plant, monocotyledon, which likes temperature and humidity, about 1 meter tall when mature, and has slender leaves, about 50 to 100 centimeters long and 2 to centimeters wide.

The flowers of rice are very small, and when they bloom, the main flower branches are arched, and small flowers bloom between 30 and 50 mm below the branches, and most of them are self-pollinating and bearing seeds, called panicles. The size of the rice kernel is generally 5 to 12 mm long and 2 to 3 mm thick.

It is an annual grass with 24 chromosomes.

Rice likes high temperature, humidity and short sunshine, and the soil requirements are not strict, and the paddy soil is the best. The minimum temperature of seedling germination is 10 12, and the optimal temperature is 28 32. The average daily temperature of tillering stage is more than 20, and the appropriate temperature of panicle differentiation is about 30. Low temperature prolongs the differentiation of branches and spikelets.

Heading temperature 25 35. The optimal temperature for flowering is about 30, below 20 or above 40, and fertilization is seriously affected. About 500,800 kg of water is required for every 1 kg of paddy formed.

Rice is a fibrous root system, adventitious roots are developed, panicles are panicles, and self-pollination. It is an annual rice cultivation and cultivation of cereals. The stalk is erect and 30 100 cm high.

Leaves alternate, linear-lanceolate, leaf tongue membranous, 2-lobed. panicles loose; Spikelets oblong, flattened on both sides, containing 3 florets, the spikelets are extremely degenerate, leaving only traces, the apex florets are bisexual, the outer barley is boat-shaped, and there are miscanthus; stamens 6; Degenerate 2 flowers are left only under the flowers of both sexes, and are often mistaken for.
