How to farm scientifically? What should I pay attention to? What are the benefits of scientific farm

Soil improvement and scientific farming are inextricably linked. The positive effects of soil improvement are really not unfounded. You will gain true knowledge when you have a thorough and in-depth understanding of soil improvement.

The so-called soil improvement is the process of taking corresponding physical, biological or chemical measures to improve soil properties, improve soil fertility, increase crop yield and improve the soil environment for human survival in response to the poor texture and structure of soil.

Cultivation of strong seedlings: Cultivation of strong seedlings is one of the key technical measures to increase rice yield. Production practice proves that the cultivation of strong seedlings should be cultivated with soil and soil to protect seedlings.

In rice seedling raising, we should vigorously promote the application of dryland seedling raising technology, which has early growth and rapid onset, no obvious regreening stage, and effective tillering.

It has the characteristics of high rate, strong resistance and high seed setting rate. Dry-raised seedling beds should be applied with more fully rotted farmhouse fertilizer.

Select excellent varieties with high yield, high quality and strong resistance to diseases and insects according to local conditions: according to local ecological conditions, production conditions, economic conditions, cultivation level and the occurrence of diseases and insect pests, select high-quality and high-yielding varieties that have been approved and tested and demonstrated to be suitable for local planting, with strong resistance to diseases and insects, resistance to lodging, strong tillering, high panicle rate, large panicle and high seed setting rate.

Reasonable irrigation: During the growth period of rice, in order to promote the good growth of the root system, enhance the absorption capacity, and promote the growth of rice. In terms of water management, the purpose is to enhance the vitality of the root system by increasing oxygen and aeration, nourishing and revitalizing roots.

Appropriate deep water irrigation was beneficial to the rejuvenation stage, shallow irrigation was maintained at the booting stage, the first heading stage and the full heading stage, and the rest of the irrigation conditions were mainly moistened. The tillering stage requires shallow water to promote tillering, and in the later stage of tillering, it is advisable to properly dry the field and control tillering, reduce ineffective tillering, increase permeability, promote the growth of rice, and should not be re-sunned when drying the field and controlling tillering; In the dry season, it is necessary to resist drought irrigation to avoid dehydration affecting rice.

appearance quality and cooking and eating quality; During the grain filling and maturity period, it is necessary to achieve dry and wet strong seeds; Drain and dry the field at the yellow maturity stage to promote maturity; When harvesting, make sure that there is no water in the field to avoid rice.

Soaking in water affects the quality of the rice.

You can first learn and understand the way of farming, so that you can farm scientifically. It is necessary to pay attention to the way of farming, the way of sowing, the degree of protection of the field, and the protection of the environment. The benefits of scientific farming are that it can protect the soil, protect the environment, increase crop yields, and increase income.

Master the scientific sowing method, at the right time, with good seeds to plant, is scientific farming, pay attention to the drainage of the soil, choose pesticides, and fertilizers, the advantage of scientific farming is that it can improve the yield of crops and prevent pests and diseases.

Master the scientific farming method, choose excellent varieties, sow seeds in well-drained and nutritious soil, the advantage of scientific farming is to improve the yield of crops and standardize the operation.

Be sure to clean up the insect infestation, and then choose loose and breathable soil, do not be exposed to the sun for too long, and ensure a reasonable spacing.

In the process of planting, the land should be turned over first, and then some fertilizer should be added, so that there can be a high yield.

There are so many ways to farm scientifically.

First, traditional agriculture is to eat different vegetables in different seasons, but now hometown farmers have anti-seasonal cultivation techniques, and they can eat summer vegetables such as cucumbers and eggplants in any season, as well as vegetables suitable for winter growth such as coriander.

Second, the original rice transplanting was done by hand, but now the dry direct seeding technology is adopted, and the rice is no longer transplanted manually facing the loess with its back to the sky.

Clause. 3. Traditional agriculture only knows how to fertilize crops on the soil, but now they all know the fertilization method of combining soil fertilization and extra-root fertilization.

What scientific farming methods are used in my hometown to illustrate the examples?

1 harvester. 2. Introduce new varieties. 3 machine seeding.

1. Machine harvesting.

2. Introduce new varieties.

3. Vegetable greenhouses.

4. Mulch film flowers.

5. Machine seeding.

6. Sprinkler irrigation.

It depends on where you are, what kind of soil you have, what kind of climate you have, and what crops are suitable for planting.

Some vegetables such as turnips, peppers, lettuce, carrots, lettuce can be grown.

Among them, the cultivation techniques of peppers are:

1. Suitable temperature.

The temperature requirements of chili peppers are somewhere between that of yarrow and eggplant. The suitable temperature for seed germination is 23-30, and it cannot germinate if it is lower than 15. Pepper seedlings require higher temperatures, low temperatures, and slow growth.

The suitable temperature is 20-25 during the day and 15-20 at night at the early stage of flowering and fruiting, and the soil temperature is too high during the fruiting period, especially the strong light directly on the ground, which is not conducive to the growth of the root system, and is easy to cause toxin disease and solar burn.

2. Soil preparation base fertilizer.

Peppers should not be cropped in combination, nor can they be combined with eggplant, tomatoes, potatoes, tobacco and other crops of the same family. Cultivating pepper plots should have good drainage, easy drainage and irrigation, and require deep ploughing. It is best to do winter ploughing and fallow permafrost to improve the soil and eliminate overwintering pests and spores.

3. Sowing seedlings.

Seedbed selection: The seedbed should be selected from north to south, with high dry and refreshing water, convenient water sources, and has not been planted with solanaceous crops.

Seedbed preparation: The seedbed is best to dig deep in the roasting soil, splash a layer of human and animal manure on it, dry it, cover it with film, and carry it to prevent the loss of fertilizer when it rains.

Sowing: Before sowing, the bed soil is fully watered and leveled. The width of the seedbed is generally suitable for meters. Generally, it is not soaked to promote germination. Early-maturing seeds are generally sown in January, late-maturing seeds are generally sown in February-March, and 75-120 grams are required to plant Changnaxiang per acre.

Seedbed management: after sowing to before the emergence of seedlings, generally do not need to manage, found that the seedlings began to emerge, to immediately remove the mulch, otherwise the formation of tall seedlings. After the seedlings emerge, the film is uncovered at 9 a.m. on a sunny day, and the film is still covered at 4 p.m.

4. Colonization. The planting of pepper should be above the soil temperature of 15, and the early planting is due to the low soil temperature, the growth is slow, and the flowers are dropped, and the purpose of early maturity can not be achieved. Planting distance, early varieties row spacing 40-50 cm, plant spacing 26-33 cm, each hole resistance l 2 plants, late-maturing varieties row spacing 66-73 cm, plant spacing 50-60 cm, 1 plant per hole.

Choose a sunny day to plant in the afternoon, and the seedbed needs to be watered in the morning to facilitate the seedlings.

5. Field management.

Cultivating and weeding: After planting, shallow cultivation should be done once in time. The plant begins to grow, focusing on cultivating once. Before the plant is closed, it is cultivated again. Cultivating combines weeding and soil cultivation.

Fertilizer and water management: After planting, it is necessary to apply "fertile leaf water-soluble fertilizer" on sunny days, and the amount of each application should not be too much or too concentrated, otherwise it is easy to cause growth and delay flowering and fruiting. When.

After the first and second layers of fruiting, more fertilizer should be applied to promote the growth of the fruit.

Harvesting and retaining seeds: As fresh food, most of them harvest green fruits, but they can also harvest red fruits. As a dried pepper, the red and ripe fruits must be harvested, and the harvest must be timely, otherwise the growth and fruiting of the plant will be affected.
