How to fertilize rape in summer? Can you share some tips?

Canola is a common crop and is loved by every household. The root system in the ground is very developed, and the depth in the soil is also relatively deep, when planting rapeseed, you can choose to retain water and fertilizer, aerate loose soil, because rape has high requirements for soil, so you must choose soil rich in organic matter. Rapeseed is very widely distributed throughout the country, and most areas can be planted, and fertilization is also very important for planting rapeseed.

Because fertilization can make rapeseed produce high yields, it is necessary to apply sufficient basal fertilizer when planting rapeseed at this time. The size of rape is relatively tall, and the amount of fertilizer required is more, so it is necessary to apply more base fertilizer, if the amount of fertilizer is insufficient, it will lead to rape seedlings are very thin and weak, which will also affect the yield of rape, when applying base fertilizer, organic fertilizer can be used as the main fertilizer, and fertilizer can be used as an auxiliary material, so that you can lay a good foundation for rape.

In the later stage, it is also necessary to carry out reasonable topdressing, always observe the condition of rapeseed seedlings, and timely demand nutrients, at this time, you can use the temperature to promote the growth and development of rapeseed, and lay a good foundation for the high yield of rapeseed. The key to the growth of rape is fertilization, because rape will absorb more nutrients in the growth, and only in this way can it grow steadily and have more particles in spring. But scientific management is also crucial, and canola generally prefers to grow in cooler weather.

According to the habits of rapeseed, it can be planted in March and April in spring, if the rape is planted too early, it will be damaged by the cold, and if the planting time is too late, the quality of rape will also deteriorate. Rape is a crop that needs more boron, and it is very sensitive to boron, so when some soil lacks greenhouses, it is easy to produce flowering but no fruit, and this phenomenon can be applied with some boron fertilizer to increase yield. Foliar spraying can be chosen, which saves on the amount of manure used in the shed and thus reduces costs.

When the camera, you should first choose farmhouse fertilizer or compound fertilizer, use mixed soil burial method to fertilize rapeseed in time after rain, ensure sufficient sunlight in time after fertilization, and try to fertilize in the morning, these are the tips I can share.

In summer, nitrogen fertilizer should be the main fertilizer, and try to fertilize and water at the same time in the evening, so that it is not easy to burn seedlings.

It is necessary to use fertilizer according to the growth of plants, reasonable top dressing, and fertilizer accumulation is needed before planting, and the use of fertilizer is not the same in different places.

To apply a sufficient amount of basal fertilizer, to carry out reasonable top dressing, must be applied as soon as possible seedling fertilizer, fertilizer should be applied according to the growth of rape; OK.

Rape is a more common vegetable in life, most people will choose to plant rapeseed at home, fertilization in the process of planting rape is actually a more important praise, because rape is a very fertilizer-resistant crop, the root system is also more, so you must apply foot fertilizer before fertilization, otherwise it is easy to affect the yield and quality of rape. In the rapeseed growth cycle should also be reasonable top dressing, so as to ensure that the rape is able to consume enough nutrients, in the rape fertilization, you can use organic water-soluble fertilizer, this fertilizer is rich in nutrients, is able to improve the rapeseed disease resistance and lodging resistance. And when fertilizing, it is also necessary to pay attention to ploughing and deep application of the soil.

The demand for fertilizer in rape during the growth period is relatively high, especially in the flowering period, the demand for fertilizer is relatively high, especially for nitrogen fertilizer, which will be more than potassium fertilizer. Therefore, in the process of topdressing rapeseed, we should ensure that the base fertilizer is sufficient, and then add some nitrogen fertilizer, but in the process of topdressing, we also need to adjust the amount of fertilizer appropriately according to different land and rapeseed growth.

When rape flowers enter the flowering period, they must be sprayed with boron on the foliage of rape flowers in time, because if the boron in the soil is insufficient, rape flowers will not be particularly solid, which will cause some physiological diseases, which may have a certain impact on the yield of rape flowers. Fertilization must be principled, not blind fertilization, must use different fertilization methods and links, so that rape flowers can fully absorb nutrients, so as to achieve the effect of increasing yield, otherwise it will have an impact on rape.

Finally, rape is divided into spring rape and winter rape, and there will be certain differences between the two, so in the pre-trembling process of planting, it is also necessary to fertilize according to the rape in different seasons.

It is necessary to pay attention to the use of base fertilizer, need to be reasonably fertilized, and the root shortage is used according to the growth of the plant.

Animal manure can be taken. The manure is usually packed into a box and pumped into the rape field.

On the basis of the original fertilization, it is necessary to increase by 20%, to control the dosage, to spray must be uniform, must be careful to strengthen field management, and remove the part of the mold sail with problems.

We may only know when the rape flowers bloom, because the rape flowers can be regarded as a beautiful landscape, but we don't necessarily know when the rape flowers start to be planted. The block should be prepared before the winter to apply a good bottom fertilizer, after planting a small water, so as not to reduce the ground temperature more watering, and then can be planted on the surface of the bow pole, covered with film, speed up the seedlings, early market. Note that the film must be tightly pressed and compacted around it to prevent wind damage.

<> plants can be planted in rows with one row spacing but in cold spring areas, sowing can be done as late as May, and early varieties can be harvested in July. It is mainly distributed in the alpine areas where rapeseed cannot safely overwinter, or where the previous crop is too late to be harvested and planted before winter. Northern, western and northeastern China, as well as mainly distributed in Anhui, Henan, Sichuan and other places.

Canola is highly nutritious and high in vitamin C. Rapeseed generally grows in places with relatively humid climates, such as southern China. Rape also has many uses, such as rape flowers when they are not budding, but if it is reserved land in winter, the land is ploughed and fertilized in the first month.

Remove weeds and do a good job of pesticide control, and use carbon and ammonia compound fertilizer urea, deep construction and fertilization to do a good job of bottom fertilizer. The appropriate amount of organic fertilizer is necessary for the growth of spring rape. In the northern, western and northeastern parts of China, as well as in the northern part of Europe, spring rapeseed is the main plant, so the productivity per plant is low.

The cultivated variety of spring rape generally belongs to the spring type. We may only know when the rape flowers bloom, because the rape flowers can be regarded as a beautiful landscape, but we don't necessarily know when the rape flowers start to be planted. Different regions have different temperatures and environments, so when planted, the seeds germinate.

In the spring drought, it should be sown with moisture or topping, generally in mid-April. Rapeseed grains are small, the ability to unearth is weak, and the land must be carefully prepared, and the ground must be carefully raked and leveled before sowing. At the same time, seeds with a high germination rate were selected and sown to a depth of 3 cm.

Skillful fertilization of rapeseed should be treated separately according to the appearance and growth of rapeseed. The seedlings are weak, the growth of the poor field should be applied as soon as possible, that is, when the height is about 50 cm, 15-20 quintals of human manure per mu, plus 5 kg of urea or 10-15 kg of 45% compound fertilizer, and the field with strong growth and dark green leaves, fertilizer should be postponed or applied less.

First of all, fertilizer should be applied at each stage of rapeseed growth, which can also play a good role in promoting growth, and can timely replenish oxygen to the soil, which can also make rape grow very vigorously at each stage.

In order to improve rapeseed resistance, disease resistance and stain resistance, potassium fertilizer has obvious effects, especially for potassium-deficient soils such as sandy fields and paddy fields in spring, potassium fertilizer can be applied in spring, and the seedlings are weak and the fields with poor growth should be reapplied as soon as possible, that is, when the height is about 50 cm, 15-20 quintals of human manure per mu, plus 5 kg of urea or 10-15 kg of compound fertilizer, and the field with vigorous growth and dark green leaves, fertilizer should be postponed or applied less.

After the seedlings are transplanted and returned to green, the earlier the better, generally 3-5 kg of urea, 5 kg of potassium chloride, 300 500 grams of boron fertilizer, 750-1000 kg of thin human and animal manure water, 1-2 times need to be applied. Or apply 45-50 kg of ammonium carbonate per mu, and return to green as soon as possible after application, so as to make full use of the high temperature after the weather is sunny and promote rapeseed to root and grow leaves as soon as possible. Wax fertilizer is mainly organic fertilizer, for medium fertilizer plots, apply 1000-1500 kg of rotted farm fertilizer, 10-12 kg of superphosphate, and kg of ammonium carbonate per mu, and mix the three fertilizers together when applied.

Then applied into the rows, combined with cultivating and weeding, so as to keep warm, promote roots, protect roots and increase fertilizer.

There are many ways to fertilize rapeseed, and it should be fertilized according to the growth condition of oilseed rape during the growing season. Try to choose farmhouse fertilizer, which is natural and pollution-free.

Fertilization can be done according to the growth situation, either farmhouse manure or chemical fertilizer can be used, which will allow the plant to grow better.

According to the advantages of fertilizer demand of high-quality rapeseed in different stages of pregnancy, nitrogen fertilizer is applied at the bottom of 50%, seedling fertilizer is 30%, and sprout fertilizer is used 20%, and phosphorus, potassium and boron fertilizer are used as base fertilizer at one time. According to the advantages of high-quality rape, especially hybrid high-quality rapeseed, which are sensitive to boron and require a large amount of boron, it is best to spray boron fertilizer at the budding stage. Bottom:

Generally, the amount of boron fertilizer applied to 1 mu is 0 5～1kg。It can be mixed with other nitrate and nitrogen organic fertilizers and applied to rape fields at the seedling stage or live broadcast room.

Generally, it is most suitable to apply to the top layer of soil. The amount of bottom application can be determined according to the reasonable boron content of the soil. In general, the soil is a suitable area with boron on top.

Rapeseed is a grain crop, and there are three types: Chinese cabbage, basket and cabbage. Chinese cabbage type and basket type multi-live broadcast room, cabbage type pre-seedling transplantation. Brassica napus has a large amount of fertilizer, good harvest performance, and relatively high yield, most of which yield rapeseed per mu is 140 160kg.

The growth and development of rapeseed goes through seedling stage, sprout stage, flowering stage, horn stage and maturity. The nutrients were abundant, and the reasonable flower bud differentiation period was correspondingly prolonged, which laid the foundation for increasing the number of horns, the number of grains and the weight of grains. The immediate supply of phosphorus can improve the drought resistance of rapeseed, promote maturity and increase yield, and increase oil content. The addition of potassium can alleviate the presence of sclerotinia and promote the production of stems and branches.

Winter rape is a winter crop, and it is often a dry crop of water and drought rotation, the soil is prone to phosphorus deficiency, coupled with the low soil temperature at the seedling stage, the phosphorus supply capacity is weak, and it is necessary to attach great importance to increasing the application of phosphorus and potassium fertilizer. The experiment showed that the appropriate ratio of nitrogen, phosphorus and potassium organic fertilizer in the production and manufacturing of rapeseed was 1 for N P2O5 K2O and the average value was 1.

If the yield of rapeseed per mu is 150kg, the average fertilizer nitrogen (N) per mu must be 15 17kg, and the average fertilizer application amount of N P2O5 K2O is 16-11-9 (kg). The amount of fertilizer used also needs to be adjusted appropriately according to the amount of organic fertilizer used and the level of soil deficiency.

The application of nitrogen fertilizer, although more nitrogen fertilizer must be used at the seedling stage of rapeseed, it is not suitable for excessive use. Too much nitrogen fertilizer is very easy to cause winter rape to grow, and the nitrogen fertilizer generally applied can be moderately filled at the seedling stage. In the initial application of nitrogen fertilizer as base fertilizer, 60% can be applied to the soil as base fertilizer, and 40% can be used as winter fertilizer and sprout fertilizer to carry out top dressing.

The use of potassium fertilizer, whether potassium fertilizer is round to the growth and development of rapeseed, and the density of oil have different degrees of harm. In addition to the early application of about 80% as a base fertilizer, the rest should be carried out in the rape sprouting stage, and the leaf spraying fertilizer should also be carried out in the rape blooming and poding stage, and the spraying can use potassium dihydrogen phosphate urea solution day up to 2116.

Rapeseed planting is the main source of extracting edible oil, all over the country are large-scale planting, its variation is more, the key is Chinese cabbage type, cabbage type, general vegetable type, according to the climate of each region, cold differences, colder areas in the spring temperature is stable above 3 can be sown, summer is not early autumn harvest, warmer areas to autumn 9 October sowing as the leading, seedlings winter, harvest next summer, planting and sowing methods due to the type and local planting habits are different, there are dry seed sowing, hole sowing and immediate sowing method, and seedling transplanting method (Chinese cabbage type, cabbage type).

Regardless of the kind of sowing method, the use of chemical fertilizer and the fertilizer in the camp is basically the same, a little management method, there will be a harvest, but to get a bumper harvest and high yield, it is true that we should also master the fertilization technology and methods of rapeseed, and immediately, scientifically and reasonably provide rapeseed with different growth period nutrient requirements, promote normal growth and development, and lay a reasonable condition for rapeseed to get high yield. Rapeseed needs more fertilizer and good fertilizer tolerance, so the base fertilizer must be applied sufficiently, with more potassium content is dominated by high-quality agricultural fertilizer, and with each other with base fertilizer, phosphorus and potassium fertilizer.

In the use of nitrogen, phosphorus and potassium organic fertilizers, rape needs 11 12kg of pure nitrogen, 6 pure phosphorus and 8 10kg of pure potassium in 1 mu during the whole growth period. Rapeseed seedling stage. Generally from January to 1 and a half months, the digested and absorbed nitrogen, phosphorus and potassium at this stage account for about % of the whole growth period, and the demand for various nutrients is not much, but it is the most basic growth link.

Seedling stage in the field.

Generally, the seedling period of rape planted above the moon and in the live broadcast room is around the month. At this stage, the digested and absorbed nitrogen, phosphorus and potassium accounted for % of the intake of the whole growth period, and this period is a long link period of rapeseed growth period, which is the stage when more fertilizer is needed and indispensable for immediate supply.

Rapeseed moss extraction stage. From the budding stage of rape to the beginning of flowering, it is about 1 month long, which is the stage when the most nitrogen and potassium are digested and absorbed during the whole growth period, accounting for about 40% each.

Fifth, five into five, digestion and absorption of phosphorus accounted for about twenty percent. Therefore, rapeseed fertilization should be based on the characteristics of the need for organic fertilizer at different stages of rapeseed and the fertilizer supply status of the soil layer, so as to ensure high yield and income generation of rapeseed.
