The scientific planting technology of kiwifruit is often cultivated in scaffolding.

Varieties: the improved varieties with large fruit shape, good quality, strong disease resistance and high yield were selected. To build the garden: choose the leeward facing hillside or open land, and the slightly acidic sandy loam with loose and good drainage and high organic matter content is better. Cultivation: dig a good planting hole and apply base fertilizer, which can be planted from defoliation in autumn to sprouting in spring. Scaffolding: scaffolding cultivation is often used. Management: wipe off the overgrown side vines after sprouting in summer. Pollination and fruit thinning: flower thinning and fruit thinning should be early, leaving 1 fruit per node on the fruiting branch, thinning lateral fruit and leaving intermediate fruit.

Kiwifruit pulp is delicious and nutritious, so it is deeply loved by people. There are several varieties of kiwifruit, there are yellow heart, red heart, green heart kiwifruit, in fact, yellow heart and red heart kiwifruit is the most nutritious, so the price will be slightly higher. So how to grow kiwifruit?

Scientific planting techniques of kiwifruit

1. Select varieties. Good varieties with large fruit shape, good quality, strong disease resistance and high yield, such as Hayward, Allison, Bruno and so on, should be selected.

2. Select and build the garden. Kiwifruit is fond of cool and humid environment, afraid of drought, waterlogging, wind and cold, but not resistant to the late frost in early spring, so kiwifruit orchards in mountainous areas should be selected in leeward slopes or clearings. The soil should be loose, good drainage, high content of organic matter, pH 5.5-6.5 slightly acidic sandy loam.

3. Cultivation methods. Before planting, dig the planting hole, the diameter of the hole is 1 meter, the depth is 40 to 50 centimeters, each hole is 40 to 60 kilograms of compost, 20 grams of phosphate fertilizer, 400 grams of silicon-calcium phosphate fertilizer. The planting time can be from defoliation in autumn to before sprouting in spring, but it is better before the shoot bleeding period in late October in autumn and late February in spring. The row spacing is 4.6 m × 6.0 m. In order to increase the early yield, close planting according to 2 times the number, thinning after mature, and mixed planting of 20% of pollinated male plants.

4. Set up a fight. Generally use scaffolding cultivation, there are scaffolding type, arch bridge tunnel type and fence type, horizontal scaffolding is the most suitable.

5. Summer management. After sprouting in summer, the overgrown side vines should be erased. From June onwards, always tie up the new tips so that they are evenly covered with noodles. As a result, 10-15 nodes were left in the branches, 15-20 nodes were left in the vegetative branches, and the rest were removed.

6. Artificial pollination and fruit thinning. First, the pollen of male flowers is diluted to 10 times with stone pine nuts, and then pollinated with cotton swabs. In addition, the male flower branch can be attached to the female branch, or the insect can transmit pollen. The standard of flower thinning and fruit thinning is as follows: one fruit per node on the fruiting branch, one lateral fruit and the middle fruit. The leaf-fruit ratio can also be used as the standard, that is, one fruit is left for every 4 to 5 leaves. Generally speaking, weak fruit branches with a length of 20 cm leave 2 fruits, fruit branches with a length of 20 cm and 60 cm have 3 fruit branches, and fruit branches with a length of more than 60 cm have 5 fruit branches, leaving 20,000 fruits per 1.5 mu.

Points for attention in collecting pollen

1. The best time to pick flowers is 9:00-11:00 on sunny days and 17:00-19:00 in the afternoon. Don't pick wet flowers or flowers with heavy dew on rainy days or rainy days.

2. The flowers harvested should be male kiwifruit flowers, and the flowers should not contain impurities such as female flowers, pedicels, sand, branches, leaves and so on.

3. If the main flower reaches the harvest standard, please be careful not to pick the bud of the ear flower when picking the main flower. The ear flower can also produce pollen when it is mature.

4. do not pile the flowers after harvest, store them in small batches in breathable bags or cardboard trays in the shortest possible time, and keep them away from the sun and in a cool, dry place.

Environmental requirements of kiwifruit planting

1. Moisture: water is the most basic component of kiwifruit. Water must be involved in all kinds of life activities. Insufficient or excessive water will affect the growth and development of kiwifruit. Kiwifruit has shallow roots and is not tolerant to drought, so kiwifruit should be irrigated timely and reasonably in growing season, high temperature and drought, replenish enough water and reduce the temperature of the tree. Kiwifruit can grow well in an environment with rainfall of about 1000 mm and air relative humidity of 70% and 80%.

2. Soil: soil is the basis of the growth and development of kiwifruit, and the nutrients and water it needs are mainly taken from the soil. Various physical and chemical properties of soil directly affect its growth and development. Kiwifruit likes sandy soil with deep soil, fertile and loose soil, good water retention and drainage, and high humus content. Therefore, attention should be paid to the selection and improvement of soil during cultivation. Kiwifruit also has certain requirements on soil acidity and alkalinity. Kiwifruit can grow normally in the range of soil PH5.5-6.5. Iron deficiency yellowing occurs in the subtractive soil above PH7.5, so it is necessary to take timely measures to improve the conditions needed for kiwifruit in order to get good growth results.

3. Temperature: temperature is one of the important factors affecting the growth and development of kiwifruit. It can grow normally in the area where the annual average temperature is above 11 ℃. The sprouting of kiwifruit is very sensitive to the requirement of air temperature. the average temperature of kiwifruit sprouting is relatively stable, and its biological transmissivity is 8 ℃. If the daily average temperature is higher than 8 ℃, it begins to germinate and grow, and the daily average temperature is lower than 8 ℃, its growth will be affected. The long sunny, high temperature and dry weather in summer will also affect the growth and development of kiwifruit, such as falling leaves, fruit or withered shoots.

4. Light: the light requirements of kiwifruit vary with age, young seedlings like shade, adult plants like light, under good sunshine conditions, the tree is strong, blossom and bear fruit. The sunshine hours affecting the yield and quality of kiwifruit in the natural distribution area are mostly between 300 and 2600 hours, which generally meet the requirements of light during its growth and development.

The efficacy of kiwifruit

1. Prevention of depression: scientists have found that kiwifruit can effectively regulate intracellular hormones and nerve conduction effects, and can effectively help patients with depression to stabilize and calm their mood. In addition, the natural inositol contained in kiwifruit can help our brain activity, and the effect of promoting this emotional stability can be guaranteed.

2. Prevention of cardiovascular and cerebrovascular diseases: 1/3 of the fiber contained in kiwifruit is pectin, especially the contact between skin and pulp. Pectin can reduce the concentration of cholesterol in blood and prevent cardiovascular disease.

3. Cancer prevention: kiwifruit contains a substance called anti-mutation glutathione, which helps to inhibit the induction of cancer gene mutation and has a certain inhibitory effect on cancer cells such as liver cancer, lung cancer, skin cancer, prostate cancer and so on.

4, beauty: kiwifruit is rich in vitamin C, has antioxidant function, and plays a positive role in eliminating wrinkles and fine lines of the human body. In addition, kiwifruit is rich in vitamins and dietary fiber, but the amount of fat is low, which has a certain effect on weight loss, fitness, beauty and so on.

5. Detoxification and clearing intestines: kiwifruit is also rich in dietary fiber, which can not only reduce cholesterol and promote heart health, but also help digestion, detoxification and prevent constipation. Effectively remove and prevent the accumulation of harmful metabolites in the body.

As mentioned above, if you want to grow kiwifruit, you need to master the environmental needs and variety selection of kiwifruit, learn more about pre-care and post-management, and do not plant it blindly. Kiwifruit contains a large number of vitamins, protein and amino acids, suitable for men and women, young and old, broad prospects, is a good project in the planting industry.
