What is no till and what is no till technology

Simple understanding: no plough target. After weeding, the shallow raft hoe can be used for sowing production.

It refers to the method of sowing seeds directly on the ground without fencing. It is convenient and fast, and the cultivation technology is based on the improvement of traditional crops. The disadvantage is that it affects the chemical weeding before the emergence of chemical weeding. Occurrence of exacerbation of the course of the disease.

Fences are not used for land preparation, sowing seeds are planted directly on the ground, and agricultural machinery is not used for management. The advantage is that it can be integrated, and the plant spacing and row spacing can be reasonably adjusted, and it can also be adjusted for different terrains. The disadvantage is that the production technology needs to be improved, there will be many defects, and sometimes the germination rate is not high.

No-tillage is to reduce the frequency of tillage to ensure that it does not affect food production, complete the stage of maximum simplification, and deal with the problem of "derailment of nutrient use" in black soil, so what are the benefits of no-tillage?

No-till, the full name is defensive tillage regulations, and the main goal is to avoid soil erosion. Specifically, this means tillage and cropping systems that cover at least 30% of the soil layer with residues after corn is obtained to reduce furrowing. There are three types of no-till measures:

Cover tillage, ridge tillage, and no tillage. The former uses mechanical equipment to plough the soil, while the latter two do not roll the soil.

Subsidy policy for no-tillage of corn

The corn no-tillage subsidy policy is generally related to the purchase of no-tillage seeders. In short, it is a subsidy for the purchase of agricultural machinery and vehicles. For example, in a certain area of Dalian City, the subsidy for no-tillage planting of agricultural machinery and vehicles is 20 yuan per mu.

If the total working area reaches 1,500 acres, you can get a subsidy of 30,000 yuan. And this kind of subsidy for new projects is mainly for growers, technical professional planting agricultural cooperatives. Because only large growers with industrial planting need to apply no-tillage seeders, and the purchase of no-tillage seeders can be subsidized.

The benefits of no-till

Save time to increase production and income, and farmers get rich. The no-till live broadcast room saves the cost of ploughing work. An earlier sowing date not only reduces agricultural consumption, but also helps to quickly lay off human capital and re-employ it.

Drought tolerance and temperature control, seedling protection and stability. The no-cultivated land is fast because there is straw covering on the ground, the soil ground temperature is relatively low during drought, it is not easy to "run moisture" in the gaps, it is not easy to store water after rain, fertilizer is not easy to flow out, and the production volume is also correspondingly increased.

Wangmiao resists collapse, increases fat, improves quality and efficiency. No-tillage maize has more roots on the surface, the main stem is more developed, and the lodging resistance is improved. Long-term comprehensive utilization of wheat straw can reasonably improve soil organic matter composition, improve soil fertilizer efficiency, and improve soil structure.

Ecological protection and continuous development. No-tillage planting enables straw to be returned directly to the field, which reasonably solves the problems of environmental pollution and resource consumption caused by incineration and treatment of straw.

The soil layer is not turned, which reduces water evaporation and soil erosion, and improves the soil water storage and moisture retention capacity. Soil permeability conditions and aerobic microbial activity were relatively reduced. Slows down the decomposition of organic matter and increases the accumulation of organic matter.

The number of tillage times and the damage to the soil structure by the machine are reduced, and the soil structure is improved. No-tillage cultivation technology refers to a set of cultivation technologies that directly sow or transplant rapeseed to flat fields after the harvest of the previous crops, combined with the corresponding supporting cultivation technologies to achieve high yield. The advantages of no-till are:

Maintain soil structure, good water permeability, stain resistance, and promote cooling.

The implementation of early sowing and early planting is conducive to the early emergence of strong seedlings before winter, and can also alleviate the contradiction of tight stubble. improve the quality of sowing and planting; Save labor and costs, and improve land utilization; It is conducive to disaster prevention and many other advantages. Therefore, the popularization and application of no-tillage cultivation technology of rapeseed is of great significance to give full play to the production potential of late-maturing rapeseed in Anhui Province.

There are many weeds in no-tillage rape fields, and comprehensive measures should be taken to control them. First, reasonable crop rotation. Second, cover the soil and weed.

Third, pre-cultivation and weeding. Fourth, chemical control, weed control and agricultural control are carried out 3-5 days before sowing and planting.

Within 3 days after sowing, weeding with professional drugs before sowing; Weeds should be removed before overwintering after emergence or transplanting. No-tillage direct seeding rape was sown late, the vegetative growth period was short, and the number of nodulations per plant was small. Therefore, to ensure the yield by increasing the density, it is generally advisable to fix the plant per mu under high fertilization conditions.

About 25,000 seedlings were planted under medium fertilizer conditions. No-tillage transplanting rapeseed, because the seedling stage has cultivated strong seedlings, the growing season has not been postponed, the transplanting density per mu should be between 10,000 and 10,000, high fertility field, dry planting, fertilizer level is thinner, seedlings are fine, the field is thin, late planting.

The lower the fertilization level, the higher the density. The available nutrients of no-tillage farmland are concentrated in the surface layer, and the surface layer has a strong fertilizer supply capacity in the early stage and is prone to premature aging in the later stage. Therefore, it is necessary to adhere to the principle of equal emphasis on base fertilizer and top dressing, and the proportion of top dressing is 5060. Medium and high fertility fields are applied with 15 kg of pure nitrogen, nitrogen, phosphorus and potassium per mu.

The scale is 1::

The base fertilizer should use more soil miscellaneous fertilizer, and the top dressing should follow the principle of "early application of seedling fertilizer, heavy application of wax fertilizer, early application of bitter fertilizer, and skillful application of flower fertilizer". Partial application of chemical nitrogen fertilizer should be avoided during the flowering period to reduce the occurrence of sclerotinia sclerotiorum. Potassium dihydrogen phosphate is sprayed once at the beginning of flowering.

and boron fertilizers to prevent premature aging.

No-till cultivation means not to plough the soil, reduce inputs, and use the method of inserting seeds for planting, which has the biggest advantage of low labor input cost and high survival rate of cultivation, which can be said to be a very good way.

The meaning of this word is that in the process of planting, it will generally be covered with straw, and then the seeds can be planted directly to the right location, and it will not affect the surrounding land, first of all, the survival rate is relatively high, and the whole planting process is also very simple, and will not destroy the geological structure.

No-tillage cultivation means to reduce the number of tillage to the extent that it does not affect grain production, to simplify the operation process to the greatest extent, and to solve the problem of "disjointed use of nutrients" in black soil. Its advantage is that it is particularly cost-saving, and can increase production and income, especially it can also resist drought and temperature, protect seedlings and ears, the important thing is that the no-tillage corn surface root is more, the taproot is developed, the lodging resistance is enhanced, and can effectively solve the problems of air pollution and resource waste caused by burning stalks.

That is, instead of cultivating the land, new crops are planted directly after harvesting the previous crops.

You don't need to plough the land, dig a pit and plant it directly.

It is a field that does not need to be cultivated, which is called no-till land.

Summary. Dear, I am very happy to answer for you, no-till cultivation refers to the cultivation method that does not use a plow and rake to prepare the land, sow seeds directly on the stubble, and do not use agricultural machinery for soil management during the crop growth period.

Summary. Hello, this means that the metaphor is engaged in mental work, reading and writing as a profession. In fact, it is said that "everything is inferior, only reading is high", to read reasonably, study diligently, and get ahead, the family will be exempt from paying taxes. Hope mine is helpful to you.

What does it mean to be tax-free farming in the book field.

The high bird is good and the bow is hidden. And what does it mean.

After the parable was completed, the person who contributed the effort gave up, and there was no good end, that is, he knocked out the bird but hid the slingshot.

There was no father and son before Jiangshan, and the flesh and blood were cannibalistic under the society, and the wolf still thought about the sheep in his dreams.

This means that there is no father and son in front of the country, and only people with high ability can win this country. In front of the country, relatives and brothers can kill each other, and wolves still think about how to eat sheep in their dreams.

Planting stubble crops does not take measures such as tillage, but directly sows seeds. Typical is rice and wheat.

No-tillage, also known as least tillage lead seepage, means that the soil surface of the orchard is not tilled or very little, and chemical herbicides are mainly used.

Weeding is a method of soil management. Many developed countries abroad.

This method is mostly used for orchard soil management. The so-called improved no-tillage method in China adopts the way of natural grass growth in orchards, controls the harm of weeds with herbicides, and uses the beneficial characteristics of slow aging.
