In general, what four aspects of work should we pay attention to when sowing?

Generally, we should pay attention to four aspects of work when sowing, the first is to pay attention to soil moisture, because the soil is too dry to affect the germination of seeds, and the soil is too wet will affect the increase of ground temperature. Second, we should pay attention to the quality of the seeds and do a germination test in advance. Third, we should pay attention to the soil temperature, which should be stable at a temperature suitable for sowing.

Fourth, we should pay attention to the amount and quality of chemical fertilizers.

In general, we need to pay attention to weather issues when it fluctuates. There is also the issue of seed quality. Then there is the issue of fertilization and irrigation. In addition, it is a problem of insect and disease prevention.

In general, what four aspects of work should we pay attention to when sowing? The first is to choose good seeds, the second seed to carry out germination test, the third to pay attention to the depth when sowing, fourth, to step on it with your feet, so that the soil is not too loose and easy, the seeds are dry, and the sprouts do not emerge.

When sowing, you should pay attention to temperature, humidity, soil, light, and the most important thing is the season.

When we sow seeds, we should pay attention to the first sowing of seeds, and the second is the time of sowing and the weather is in a place that is sown.

When sowing, pay attention to the time, the weather, the amount of sowing, and the well, germination of the seeds.

Generally, you may pay attention to several aspects when fluctuating, first of all, fertilization is more important, but also to plant seedlings, planting good things.

Time, the quality of the land, one's own mood, and the most important thing is whether the other party is willing or not. Don't forget to like it.

Be sure to pay more attention when sowing.

In particular, the sowing area must be as balanced as possible.

In this way, the effect of sowing can be better.

Your question is to ask, generally we should pay attention to what 4 aspects when sowing, under normal circumstances, the land is requisitioned and turned over, and then planting.

In fact, when we sow seeds, we must choose the kind that is the seed grain is relatively full.

When sowing, we must pay attention to the right time, place and people.

Generally, we should pay attention to the season, soil temperature, humidity and other issues when sowing!

Generally, when we sow seeds, we should pay attention to this certain step, step by step sowing season and sowing period and sowing distance.

Generally, we should pay attention when sowing, and this should be careful not to be. Well, overwashed or over-dense.

Generally, we should pay attention to four aspects of work when sowing, one is to look at the weather conditions, and the other is to look at the soil moisture and seed conditions.

Hello, friends should pay attention to what aspect of work when sowing, and take a look when sowing. What is the procedure?

Generally, when we sow seeds, we should pay attention to two aspects: humidity and temperature.

The seeds should be disinfected first, the seeds should also be sterilized, the condition of the soil should be adjusted, and the moisture of the soil should be adjusted, which are all preparations that need to be made before sowing.

You need to prepare in advance, you need to treat the seeds, you need to pay attention to the condition of the soil, the land definitely needs to be cultivated, you need to prepare fertilizer in advance, and you need to prepare disinfection and sterilization work in advance, so that you can plant.

We must do a good job in loosening the soil, loosen the soil and turn the soil in time, we must ensure that the bottom fertilizer is sufficient, and we must do a good job in seed and seedling raising.

The main points of sowing are as follows:

1. Do a good job of growth records, whether it is planting flowers indoors, planting vegetables in the yard, or planting trees in the nursery, it is very important to make a log, in sowing, germination, the growth rate of plants, and the annual plant transplantation period, it is also necessary to record it in detail.

2. Use wide and flat containers to prevent excessive squeezing of seeds, plastic pots and other containers are more suitable for initial sowing than mud pots, and have stronger moisturizing properties. Wide-mouthed, shallow-bottom containers prevent over-squeezing between seedlings, provide plenty of humidity for new, fragile, young roots, and plants that are sensitive to external root disturbances, are best planted in plastic containers like empty yogurt and canned cheese.

3. Throw the seeds into the bottom of the container so that they are in close contact with the soil, sprinkle the medium in the container so that its depth is 2 times the diameter of the species itself, for very small or germinating seeds with extremely high light requirements, do not cover the soil and sow directly on the surface of the pot, in either case, the sowing is kept moist.

4. Maintain the temperature around the seeds to promote germination, most seeds germinate at 18 24, the container is placed close to the air conditioner or after safety considerations, a heater is placed next to the container to further germinate at the appropriate temperature, it is worth mentioning that there are heating pads specially used for plant cultivation.

5. Transfer the pot every day to make the seedlings grow healthily, if there is no sufficient sunshine, most of the seeds can not germinate normally, but after the sunshine time reaches 12-16 hours, most of the seeds develop well.

6. Provide sufficient nutrition, continue to have appropriate nutrients to ensure the healthy growth of the plant, when the germ develops in the seed, its nutrient supply is completely dependent on the endosperm, but when the root system gradually develops true leaves in the soil, the initial nutrients are exhausted, and foreign nutrients are needed at this time, and many mediums only contain a small amount of nutrients.

7. Adapt the plant to direct sunlight, in order to transplant the plant to the vast land, in the spring, it is necessary to accept the test of coping with direct sunlight and temperature changes, the adaptation to the light is best completed within 3 days, the first morning, the plant is placed in direct sunlight, and in the following days, the time of direct sunlight gradually increases.

There are two main things that should be done before rice seedlings are planted. The first is to summarize the lessons of the previous year's bumper yield, find out the shortcomings, carry forward the achievements, put forward the measures to improve the high reform, select and match the varieties according to the actual situation, and determine the method and operation history of seedlings; The second is the necessary production conditions and sufficient material preparation, such as agricultural film, skeleton, seeds, fertilizers, agricultural fertilizers, preparations, seedling enhancers and tools.

1) Seed preparation and seed treatment: including selecting suitable varieties for string exchange, doing a good job in germination rate test, drying seeds, seed selection, soaking and disinfection, germination, germination and sowing preparation.

Qi Yujuan 2) seedling preparation and required materials: first select the seedling land, prepare the land for bed, fertilize the seedbed, acidify the seedbed (adjust the preparation, strengthen the seedlings), etc. Seedlings on bare ground can be sown after watering the bottom of the foot.

Tray seedlings (floppy disk, bowl plate), after preparing enough to destroy the spring seedling tray, the bed does not need to be acidified, hit the bottom of the water, and the bed can be placed on the seedling tray. Then, the soil is loaded, watered, and sown. The soil in the tray is pre-prepared and acidified nutrient soil.

3) Soil covering and nutrient soil preparation: mix high-quality decomposed fine farmyard manure with soil in proportion to make nutrient soil. If the nutrient soil is added with a seedling booster (or a mixture), it does not accelerate the effect of fertilizer.

If sulfuric acid is used for acid adjustment, nitrogen, phosphorus, potassium chemical fertilizer, pH should be accelerated, so as to prepare for sowing in trays or spread on the isolation layer to prepare for sowing, and the covering soil does not need to be adjusted without fertilizer.

4) After sowing, spray herbicides, cover mulch, insert racks, cover with agricultural fertilizer, and do a good job of windproof ropes.

Before rice seedlings are raised, schedules and materials should be prepared according to the needs of the above-mentioned operations.

1. Dry seeds before sowing. Seed.

After a long period of storage, it is easy to absorb moisture in the air and increase the water content of the seeds themselves. Therefore, before peeling, it is necessary to dry the seeds according to the change in the moisture content of the seeds.

2. Measure the bud potential and bud failure rate of seeds. Seeds are often lost during storage time due to poor management for one reason or another. Therefore, in order to ensure that the seedlings are sown and the seedlings are strong, the germination rate and bud potential must be tested before peeling the shell.

3. Grading and granularity. Be sure to screen the seeds. Full and complete friends, bright skin color of large seeds, nutrients, strong vitality, used to make seeds have obvious yield increase effect.

There is a clear difference between grading and non-grading of seeds, with the first grade increasing the yield of the first seed and the second grade increasing the yield, so it must be graded before sowing.

Hope it helps.
