What are the advantages and disadvantages of mechanical transplanting?

To put it simply: it can achieve the most reasonable density, the most reasonable depth, solve the labor problem, and facilitate ventilation and light transmission and field management.

Small seedlings transplanting basically do not fall seedlings.

Teacher, take a look.

You are welcome.

The realization of agricultural mechanization is an important part of China's agricultural modernization, and only through mechanized production can we continuously improve the level of agricultural modernization. In recent years, with the development of the market economy, the rural economic conditions have gradually improved, and a large number of agricultural laborers have been transferred to non-agricultural industries, creating conditions for the development of mechanization. Among them, the mechanization of rice production, as one of the important contents of agricultural mechanization, is developing steadily in economically developed areas, and its advantages can be summarized as "five advantages":

1) It is conducive to saving labor, reducing labor intensity, accelerating the transfer of agricultural labor, and promoting the development of rural market economy. The development of machine transplanting is generally more than manual transplanting per 667 meters 2 to save a worker, greatly alleviating the contradiction of labor tension during the summer harvest and summer planting, especially some large agricultural households, in the past, often due to the artificial planting of seedlings and flowers, either extensive planting, or first-class hired transplanting, increased costs. This difficulty can be easily solved after the implementation of machine transplanting.

2) It is conducive to the double yield increase of rice and wheat. The yield of machine-transplanted seedlings is the same as that of hand-planted seedlings and slightly increased, and at the same time, because the machine-transplanted seedlings use small seedlings to raise seedlings, the area of the seedling field can be reduced by 5 to 6 times compared with the hand-planted seedling field, and the saved seedling field can be a variety of wheat or rapeseed.

3) It is conducive to reducing labor intensity and greatly improving labor productivity. Machine transplanting does not need to pull the seedlings by hand, as long as the machine hand is turned on, the rice transplanter sits and adds the seedlings, and the amount of work is far less than that of hand transplanting.

4) It is conducive to the development of professional services. The transplanting machine has a large planting area, which can not only provide planting services for farmers, but also use small seedling machine transplanting, which is relatively centralized and easy to manage. Therefore, the development of machine transplanting can promote the development of service-oriented moderately large-scale operations.

5) It is conducive to accelerating the realization of the whole process of mechanization of rice. Over the years, the mechanization of rice production has developed greatly, but the weakest mechanical operation is rice transplanting, if the development of machine transplanting can be accelerated, the whole process of mechanization of rice production is just around the corner.

The advantages and disadvantages of transplanting and throwing rice are:

The advantages of transplanting seedlings are more obvious, through machine transplanting, the seedlings are more orderly, the depth is consistent, so that the ventilation and light transmittance of the field are better than the price, on the one hand, the scattered royal reduces the occurrence of open digging and ambush pests and diseases, on the other hand, effectively promote the growth of seedlings, under the same conditions, it is more conducive to increasing production and income.

Secondly, rice transplanting is with soil.

Transplanting, due to good ventilation and light transmittance, is more conducive to rapid regreening, if the seedlings in the field are more disorderly, there will be too many seedlings in a certain area, and a certain area is too thin.

The disadvantages are also more obvious, such as the cost will increase, the labor intensity is relatively high, and it is not easy to operate.

Throwing seedlings also has certain advantages, compared with the above machine transplanting, the operation is relatively simple and easy, the cost is slightly reduced, and the agricultural time is saved.

In addition, the seedlings of the seedling field are also soiled, and the roots of the seedlings in the seedling field are shallow, probably only, and the tillers are tillers.

In this case, in the later stage, the effective spike will also increase, and the purpose of increasing yield will be achieved in view of this characteristic.

Due to the rural nature, rice transplanters have not been widely used. The first is that there is less land in the countryside, more than 3,5 acres of land, and the land is not home decoration as a whole. The second is that the cost of rice transplanters has also increased, and the minimum six-row old rice transplanters also need six or seven thousand yuan, and a total of six or seven thousand yuan can be earned a year?

The third is that the rural labor force is relatively abundant, and there is no reason why the rice transplanting machine cannot be popularized in the rural areas after the rice transplanting stool is planted in three to five days.

The marketing and promotion of rice transplanters are limited by geographical conditions, especially the provisions of medium and large agricultural machinery and equipment are higher. First. The pavement should be wide and flat, second.

The fields should be large and flat. Therefore, the rice transplanter has been well marketed and promoted in the plains. Then there is the shrinking of economic conditions.

In mountainous areas and hilly areas, there are paddy fields, and it is proposed to market and promote handheld rice transplanters, which are not too high for road surfaces and fields, and are not expensive and lightweight. Whether it is marketing and promoting large, medium and small rice transplanters, don't have to learn and train a group of outstanding talents who throw seedlings in the rough world, and the seedling breeding is not very good to plant in the field.

Mechanical automation work must be flat, the field is large, it is good to operate, and how to work like a small piece of field ladder in the mountainous area, can only be planted manually, like the plain area of the household field is different, how many, there are high and low, and the planting method selected by the household is not the same, some others choose to insert the machine, some choose to throw the seedlings, some choose to plough, some choose to manually insert, in the machine insert 1 mu salary above 80 yuan, farmers are not afraid of money now, and the potato farmers are also thrifty, as far as possible in the planting of less costs, At this stage, rice transplanters cannot be promoted in rural areas.

In the case of rice transplanting, it is easy to harvest relative rice, and one person can also plant the field. In addition, the farmers' agricultural land is already very small, and many homes are all there.

In the middle of three or five acres, it is because this kind of farmer at home is idle and does not need to be at home, like women and elders at home, there is not much additional thing to do. As a result, everyone adheres to the full consideration of cost savings, and can do it themselves as much as possible. You know, ask a rice transplanter to plant rice, although the price is not very expensive, but three or five acres of land or must cost hundreds of yuan.

And I don't have to be at home, although I have to spare energy, but I can go to plant seedlings and finally earn it.

Answer: rural rice transplanting machine is not popular, I think the main reason is that China's rural areas are generally implemented responsibility system and divided fields to households, each household is trapped in the rock section of the cultivated area is only a few acres of land or even less, for such a small area of rice transplanting do not need to use rice transplanting to burn the machine, with manual trouble to save trouble and fast party rough thoughts, and the field and the field are separated, there is a field, with the rice transplanter is not very convenient.

No. Nowadays, the land in the countryside is limited, and there is basically no need to use large machines.

Because it is very slippery and sluggish in the southern region, and it is believed that Li does not use rice transplanters, the southern region is mainly hilly and cannot be used for such a large machine.

Their land is very small, the cost is high, and the labor force is relatively large, so they don't need rice transplanters at all, which has nothing to do with work efficiency.

It is beneficial to improve the rice transplanterofEfficiency

The efficiency of the rice transplanter can be greatly improved by using the rice transplanter. The daily transplanting area of the tractor-type rice transplanter (four-row machine) is about 20 times faster than that of traditional manual rice transplanting, and it also greatly saves the labor of manual rice transplanting. In addition, the seedling raising time of the transplanting machine is shorter, the quality of the seedling transplanting is high, and the maturity is earlier than that of manual transplanting, and in the same time, more rice yield can be obtained, and the efficiency of rice planting is improved.

It is beneficial to improve the economic benefits of peace and quantity

Preparation before raising seedlings

In the selection of seeds, it is necessary to choose rice species suitable for local soil and climate for planting. In addition to good lodging and disease resistance, seeds also need to be produced more safely. If you choose seeds that have not been film-coated, you must carry out seed treatment before planting and application, first soak the seeds with drugs such as strong chlorine + acetamiprid, which has the effect of eliminating germs and preventing insect diseases, and then take them out to dry and plant.

Selection of bed soil and seedling fields

In the selection of bed soil, the bed soil for rice planting is generally to choose rich garden soil, generally in the field, 1500kg of bed soil per mu of land must be used. Before the application of bed soil, 8kg of fine powder and 1kg of seedling enhancer should be added to every 100kg of fine soil, and then the bed soil should be concentrated and covered with agricultural mulch, so that the land can be fully matured and the fertility of the soil can be improved.

In the selection of seedling fields, it is necessary to choose farmland with soft soil layer, flat terrain, downwind and sunny sun, and good irrigation standards. Before planting, it is also necessary to do a good job of the seedling box, the total width of the box is about to be, the width of the ditch between the seedling boxes is more than 30cm, and the depth of the ditch is generally 20cm. In addition, the surface layer of Yangxiang Yuanchun ensures that it is "soft, solid, flat, light and straight".

Once the seedlings and seeds are ready, they can be planted gradually, but it is important to choose the right planting time and amount of seeds. According to the stubble time, tillage time and consolidation time on the side of the street, the planting time can be measured according to the seedling age of 30 days, and the temperature is stable according to 12. If the total area of the farmland that must be planted is too large, the seeds should be planted in batches according to the speed and efficiency of transplanting.

Seedling management plan

Before the three-leaf stage of seedlings, the bed soil should be mainly managed with moisture, but the water should not be too much; In order to ensure that the seedlings have old and healthy roots, Tachibana Nai drains the seedlings one week before planting. If there is a rainy day in front of the rice transplanting machine, the seedlings should be covered with a laminating film in advance to avoid the bed soil absorbing too much water and affecting the effect of the machine transplanting. It is necessary to do a good job in fertilizing seedlings and preventing pests, and bacterial wilt is one of the key pests and diseases in seedling fields.

Land resources can be sprayed with 50% Likujing wettable powder with water to treat pests and diseases, and tricyclazole can be sprayed before planting to prevent and control rice blast; Blend spraying and sprinkling. In the water management method of the seedling field, the key is to moisture management, if the seedlings occur in the morning and evening when the land is dry, there are no water droplets and the leaves are wrinkled in the afternoon, it is the seedling field with less water, and the seedling field should be watered sooner or later, and if there is continuous rainfall weather, drainage measures should be taken.

The stacked disc is darkened, and the heat preservation and moisturizing promote the emergence of seedlings, which is conducive to improving the uniformity of seedlings. The specific method is that after sowing, the seedling trays are stacked directly indoors or on the site, and covered with film, shading and darkening, moisturizing, heat preservation and promoting seedlings. Generally, the height of the stacked disc does not exceed 30 trays, and the top is empty; The stacking time is generally about 24-60 hours, when there are more than 60 buds unearthed in the sheath.

After that, it is moved to the seedling field for string arrangement.

It is necessary to adjust the power of the rice transplanter, so that the seedlings will not be planted by mistake or force, and the seedlings will die.

1) Seedling soil production. It is advisable to choose fertile soil, no stubble, gravel, weeds, no pollution vegetable garden soil, cultivated and matured dry field soil, autumn ploughing and winter ploughing paddy field soil. It is forbidden to use unrotted manure, as well as sludge, urea, ammonium carbonate and other direct mixing as base fertilizer to prevent fertilizer damage and affect the emergence of seedlings.

Seedling soil does not need to be fertilized, can be used directly after crushing, sifting, generally 20 kg of seedling soil per mu of field.

2) Soaking seeds. Encouraging germination and soaking time are the keys to ensure the efficacy of the drug and the full absorption of water by the seeds. Germination can be induced after soaking.

Rice germination standard, about 90 seeds can be "broken and exposed". After germination, the rice should be placed in an indoor stall for 4 to 6 hours for budding, and then sown on the surface of the rice.

3) Darkening of stacked discs, heat preservation and moisturizing to promote seedling emergence, which is conducive to improving the uniformity of emergence. Specific method: After sowing, the seedling trays are stacked directly indoors or on the site, and covered with film, shading and darkening, moisturizing, heat preservation and promoting seedlings.

Generally, the height of the stacked disc does not exceed 30 trays, and the top is empty; The stacking time is generally 24 60 hours, when there are more than 60 buds unearthed in the sheath. After that, it is moved to the seedling field for string arrangement.

Personally, I think that if you want the germination rate of seedlings to be higher at this time, you must do a good job of relevant specifications in advance at this time, and give it enough nutrition.

Small walk-behind rice transplanter. This type of rice transplanter is the cheapest rice transplanter, and it is also the slowest rice transplanter with the slowest operation efficiency, commonly known as "water floating", with a general operating area of 15-20 acres a day. Although this rice transplanting machine also has the power to drive, Kubota machine is expensive, and now the ** that has been fried has been more than 3,000 yuan higher than last year and the year before last, the machine is lightweight, and the rice transplanting speed is fast, but the quality is not as good as Yanmar, and the accessories are not cheap, especially the rice transplanting box has two gears, one large and one small, and a set of more than 1,000, <>

It's really a bit difficult to use it for yourself, the following is what I know about sorting out some different brands of rice transplanters, for the reference of farmers and friends, you can choose the new rice transplanter you want to buy according to your own economy and needs.

In the era when labor is not valuable, manual transplanting is the mainstream of cultivation, with the reduction of rural labor, the area of manual transplanting is becoming less and less, in order to reduce costs and improve efficiency, people turn to throwing seedlings and machine transplanting. Now people are smart, and they like the simpler the better, so that the young people of today go to the rice planting estimate that no one wants to do it, how do you save trouble now, the key is that this kind of live broadcast is very good, it is better than rice planting, so it is recognized and promoted by everyone, the first choice for four-wheel drive rice transplanters Kubota followed by Iseki and Yanmar, but the hell conditions are also different, each with its own advantages and disadvantages. Machine work is one thing, but the operation of the machine operator is also crucial, personal opinion.

Because the efficiency of rice planting is not good, people are actively exploring new ways to improve the efficiency of rice planting. The direct seeding of rice has become a method that people pay close attention to.

If rice wants to have a high and stable yield, it is necessary to take the road of sowing seedlings and cuttings. Therefore, with the advancement of rural land intensification, the road of agricultural mechanization is imperative, and agricultural mechanization will also become the main force of agricultural production. Due to the transfer of rural labor and the continuous increase in labor costs, direct seeding rice has been gradually promoted throughout the country as a new cultivation method for more than ten years because it can reduce seedling raising and manual seedling allocation and planting.
