Everyone loves good-looking and delicious carrots, and for a cute farmer who grows carrots, it must be a smile to grow carrots with good strips, good colors and good taste.

Asia-Africa Seed Industry has been in the carrot field for eight years and has many excellent carrot varieties, especially Asia-Africa 16004 is the most outstanding, which is widely recognized by growers in Shandong, Bashang and other places.

Why is Asia and Africa 16004 so popular?

What are its advantages over other varieties?

What can it avoid affecting quality?

A good carrot is always one in a million. It must stand out among many excellent varieties, and it must have its advantages:

01

Color red

The color is deep red, and the skin color and core color are good. In fact, when it was first photographed, it was precisely because of its color. Among the hundreds of varieties that were eliminated before that, most of them lost in color. Three high degree of redness, natural beauty, looks good!

02

Good neatness

Good neatness means less defective products, excellent bar shape, output, and yield rate.

03

Petiole upright, good disease resistance

Strong and upright petioles and dark green leaves can better promote photosynthesis, absorb nutrients, and the plant's own resistance is greatly enhanced.

04
耐抽苔

亚非16004播种后110天—120天采收，属于中早熟品种黑田红品种类型，耐抽苔性非常好，去除掉了人工除苔成本，提高了品质和产量。

05
口感好

具有水果胡萝卜的潜质，如果要给亚非16004打分，我愿意在口感上给它999分，还有一分留给亚非种业今后比它更***的品种。

06
菜商爱

亚非16004是一个不愁卖的品种，在去年胡萝卜价格***迷的时期，亚非16004也比其他品种要高出5分钱/公斤，亩产五千公斤，那就是每亩地多出500元。

For better quality and higher yield of carrots, for a variety like Asia and Africa 16004, we also need to use planting techniques to avoid the other side of its advantages:

1. The petiole is erect, which also means that strong light is easier to irradiate the soil and carrot roots through the leaves. Long-term irradiation will cause the carrot to appear purple and affect the quality of the carrot.

In order to avoid purple heads, we need to cultivate soil at the right time, especially one month to 15 days before harvest, when the carrots are in the swelling period, the soil is most likely to be squeezed, causing the carrot heads to be exposed on the surface of the soil. This is what we want Avoid the loss caused by this.

2. The taste is good. It is destined that the crack resistance of Asia and Africa 16004 needs to be improved. The crunchy taste makes it more suitable to be planted in semi-sandy soil. Only with good varieties and good land suitable for it can its value be maximized. no?

3. The ability to pierce is not strong, which is the characteristic of many varieties of this type. Therefore, ridge planting is required, and water control management after the first permeation is required to facilitate root piercing.

Avoiding these points, it’s hard to think about the beautiful Asian and African 16004!

Carrot cultivation technology

One sowing

1. Soil preparation and fertilization

①Site preparation: Carrot fields need to be leveled, there is no mulch, straw and other sundries in the field, no herbicide residues, and the land is kept clean and tidy. Carry out deep rotary tillage of the land to ensure that the soil is not compacted. The depth of rotary tillage is generally about 30-35cm.

②Fertilization: After the land is rotary tilled, use a fertilizer applicator to apply base fertilizer. Fertilization and secondary rotary tillage are carried out at the same time. Use about 50kg of balanced fertilizer with 15% N, P, and K content per mu.

2. Seeding

① Seed treatment: Seed rope weaving, under normal circumstances, the seed spacing of weaving rope is 3:3:6cm. When the bud rate is ≥95%, 6cm single-grain rope can be braided; when 70%≤the bud rate is ≤85%, 3cm single-grain rope can be braided. The length of braided rope per acre for double-ridged four-row planting should be about 2000m; for flat-ridged four-row planting, the length of braided cord per acre should be about 2100m.

②Ridging: Generally, the Bashang area can be divided into double-ridge four-row planting and flat-ridge four-row planting. We recommend a ridge width of 70cm and a ridge height of 15-18cm for double ridges and four rows; we recommend a ridge width of 130cm for flat ridges and four rows.

③Sowing: The planter is equipped with a braided rope reel, and the general planting depth is about 1cm. After the braided rope is buried in the soil, it needs to be covered with soil and compacted; double-ridged four-row planting (four rows of flat ridges are also acceptable) need to be in the two rows of carrots The drip tape should be buried in between, and the distance between the drip holes of the drip tape is recommended to be about 15cm, and the holes shall be opened on both sides.

④ Herbicide: spray pre-emergence herbicide after sowing to avoid removing the film and weeding. It is recommended to use Shitian tonic for herbicides to avoid phytotoxicity or poor effect.

⑤ Laminating: When the temperature is low, use plastic mulch to keep warm; after the temperature rises, it is recommended to use non-woven fabric; when the temperature is high after emergence, open the vent of the plastic mulch in time to avoid excessive temperature and scald the seedlings.

Two field management

1. Fixing seedlings: It can be carried out on 4 carrot leaves, plucking out inferior and diseased plants that are too dense, and generally keep the plant spacing about 6cm. The fixed seedlings should be fine, which plays an important role in the quality of the later carrots.

2. Top dressing: Carrot top dressing is generally divided into 3 times

①For the first time, water-soluble fertilizer is the main one. Before and after the seedlings are set, the water-soluble fertilizer is applied 20 kg per mu;

②The second topdressing time should be about 2cm in diameter of carrots, and 20 kg of high-potassium water-soluble fertilizer should be applied per mu;

③For the third time, about 20 days after the second topdressing, apply 20 kilograms of high-potassium water-soluble fertilizer per mu.

3. Watering:

①Sprouting water must be sufficient to ensure that the seeds have enough water to germinate;

②The field moisture is generally controlled above 70%, and water should be watered in time and thoroughly if it is below 70%;

③For varieties with short roots, water control can be used to increase the length. Generally, water control starts after the seedlings are fixed. When the diameter of the carrot is about 1.2cm, stop watering, and control the moisture in the soil at about 50%-60%, and the duration is about 7 days.

Three pest control

The prevention and control of carrot diseases and insect pests generally starts after the seedlings are fixed, usually once every 10 days.

Downy mildew: can use DuPont Kelu to prevent and cure.

Disease: Azoxystrobin can be used for prevention and treatment.

Black rot: Kasugamycin can be used for prevention and treatment.

Causes of Four Carrots' Fleshy Roots Forking

1. The radicle dysplasia: the radicle is weak, deformed or damaged by low temperature, and it is easy to bifurcate prematurely during germination;

2. Physical damage: In the process of radicle rooting, encountering underground pests, soil debris, soil too hard, or abrasion of fixed seedlings, etc., will cause the supplement and flocculation of meristems and develop into fork roots;

3. Chemical damage: When the concentration of chemical fertilizers, immature organic fertilizers, herbicide residues, etc. is too high, the osmotic pressure is too high, which will cause the carrot root tip cells to be destroyed and cause bifurcation;

4. Overnutrition: When the density of carrots is too thin, the nutrient area of a single row is too large and the nutrients are inhaled too much, which can also promote the hypertrophy of the lateral roots and cause bifurcation.

Reasons for the split roots of five carrots

1. Lack of boron and calcium. Boron is responsible for the stability of cell division, while calcium is related to the toughness of the cell wall. Once lacking, cell tissues are loose and disorderly arranged, and cracking becomes the most common manifestation. There are more recropping plots;

2. Inappropriate moisture and temperature conditions, especially in the middle and late stages when carrots expand rapidly, the cambium continuously differentiates into new cells and pushes outward. At this time, the higher the temperature, the faster the expansion speed. If it encounters low temperature or cold water Watering, the surface of the radish first shrinks when cold, stops or slows down its development, while the internal growth is still going on, thus forming a longitudinal crack from the inside to the outside.

Generally, stubbles harvested in early spring protected fields or spring open fields are most prone to cracking due to frequent moisture changes and temperature changes.
