Where is the most authentic kiwifruit with hearts? What are the planting techniques?

Actinidia chinensis is a kind of edible and medicinal fruit with high vitamin content. So what are the planting techniques of kiwifruit? How to choose in life? Let's take a look at it next.

1. Planting techniques of Actinidia chinensis

It is better to choose mountainous areas with convenient transportation, sufficient light, relying on water sources, moderate rainfall, slightly higher humidity, loose and well-ventilated sandy loam or sandy soil, or hilly and mountainous areas rich in humus.

1. Frame type

The main scaffolding methods for planting red kiwifruit are T-shaped frame, hedge frame, tripod frame, greenhouse frame and so on. The flat-roof greenhouse frame is mostly used, the original small diameter tree can be used as living pile on the spot, and some replaceable bamboo dirty can be added, and concrete pile can be used in key parts. The height of the on-site frame is 1.8 meters, and the vertical and horizontal intersection of No. 12 wire is a "well"-shaped network with a distance of about 60 centimeters.

2. Fertilization

The amount of fertilizer application is determined according to the variety of Actinidia chinensis, planned yield and soil fertility. Before planting, fruit wood fertilizer 2.5kg could be applied to each tree in the pothole, and a small amount of multiple fertilizers were used for young trees. After that, it is generally fertilized 3 times a year, once and twice after topdressing. Because the root of kiwifruit is fleshy root, it is necessary to dig a shallow trench far away from the root to apply chemical fertilizer and seal the soil so as not to cause root burning. Irrigation must be carried out after fertilization in the dry season.

3. Shaping, pruning and fruit thinning

Branch shaping depends on the construction mode, and the shelf surface should be fully utilized to make the branches evenly distributed so as to achieve the goal of high yield and high quality.

Red kiwifruit is divided into winter pruning, summer pruning and male plant pruning before pruning. Winter shearing was carried out during the period from defoliation to one month before sprouting in early spring. Leave more main vines and fruiting mother branches, and cut off overdense branches. Thin and weak branches, cross branches and disease and insect branches. Summer shearing is mainly carried out from mid-May to early July to remove sprouting, heart-picking, thinning and binding, timely erase the sprouts on the trunk and arrange the space for the branches.

Generally, the fruit will be thinned 1 month after flowering. Leave middle fruit, sparse edge fruit, up to 1 fruit for every 4 murine 5 leaves. The general branch leaves 1 fruit for every 20 cm, and the weak branch 20 for 25 cm, 5 for 6. The plant produces 50kg, and 600 fruits should be left.

4. Pest control

The main diseases harmful to kiwifruit are anthracnose, root-knot nematode, blight, quenching, root rot, fruit soft rot and so on. Among them, anthracnose is harmful not only to stems and leaves, but also to fruits, so it can be controlled by spraying 800-fold carbendazim 3 times during sprouting. For root-knot nematode disease, fertilizer and water management should be strengthened and 30% carbofuran poisonous soil should be used to control the disease.

After fruit picking, clean the orchard, cut off the branches of diseases and insect pests, and burn them centrally, so as to reduce the source of disease and insect infection.

5. Timely harvest

The storage life and quality of Actinidia chinensis are greatly affected by its maturity at harvest. Kiwifruit harvested too early or too late will affect the quality and flavor of kiwifruit, and must go through the quality formation period to fully mature.

According to the fruit development period, when the soluble solids content of the fruit is 6%-7%, it is the suitable time for harvest, while the fruit that needs long-term storage is required to reach 7% Mel 10%. The best picking time is when the temperature does not rise before 10:00 in the morning. When harvesting, it should be picked and put lightly, shipped carefully to avoid damage and stacking pressure, and it is best to pack it into storage along with the classification. The bottom of the containers such as boxes and baskets used to hold peaches are lined with soft village materials. Pick and place lightly, do not pull the pedicel or scratch the peel. The fruit after first harvest is hard and astringent, and must be ripened and softened for 10 days before edible.

Second, where is the most authentic kiwifruit?

The main producing areas of Hongxin kiwifruit are Dujiangyan in Sichuan, Shangyu in Zhejiang, Liupanshui in Guizhou, Xixia in Henan and so on. Pujiang in Sichuan has the largest planting area and the highest degree of management standardization, so it can be said that I have come from behind to catch up. I have also built a 2,000 mu red kiwifruit planting base in Zunyi, Guizhou.

Third, how to choose kiwifruit with hearts?

1. First of all, we have to look at the fruit type.

The shape of high-quality kiwifruit is more regular. Different varieties still have a slightly different appearance, so we can't generalize it. On the other hand, the kiwifruit with excessive use of expanding agent has a variation in fruit shape and is much more irregular.

two。 Look at the hardness.

Generally in the selection of kiwifruit, it is recommended to choose a harder one is better, the general fruit how soft or local softer, is not recommended to choose, generally soft, are not resistant to storage, easy to break. If you choose soft fruit, you should eat it as soon as you get home.

3. Look at the appearance.

Full body, uniform color, no injury or disease is better, the faint green is better, there is no bagging color brown and yellow. Several varieties of kiwifruit with a smooth appearance are all hairless.

4. Look at the size.

Small fruit is not inferior to large fruit in taste and nutrition, so there is no need to blindly pursue large fruit, let alone unusually large fruit. The weight of red kiwifruit commercial fruit is generally 80-120 grams is the most appropriate.

5. Smell the aroma.

Fully ripe kiwifruit, soft texture, accompanied by aroma, this is the appropriate state to eat. If the substance is hard and has no aroma, it means it is not mature and it will be stored for a period of time before it can be eaten. If the fruit is soft, or full of gas, and has the taste of alcohol, it is too ripe or rotten to eat.
