Seed price and planting method of kiwifruit

Kiwifruit, also known as kiwifruit, fox, monkey pear, etc., is a large deciduous woody vine of kiwifruit family. Its origin is in Xiangxi, Hunan Province, China. Shaanxi at the northern foot of Qinling Mountains is the most abundant area of kiwifruit resources in China. Folk artificial cultivation has a history of more than a thousand years. Let's take a look at kiwifruit seed prices and planting methods.

How much is the kiwifruit seed per jin?

The price of kiwifruit seeds is about 40-50 yuan per jin, but it varies according to the quality, variety, origin and market of kiwifruit seeds. Kiwifruit seedlings cultivated by seed sowing are called real seedlings, which are of great significance for introduction and cultivation in non-producing areas and non-natural distribution areas. direct seed propagation can not only achieve the purpose of introduction and domestication, but also can be used to cultivate new varieties. in production, it is mainly used to propagate rootstocks to provide material basis for grafting fine clones and strong seedlings.

What kind of environment does it take to grow kiwifruit?

1. Climate: kiwifruit is resistant to semi-shade, likes cool and humid environment, is afraid of drought, waterlogging and wind, and is resistant to early spring and late frost. It is appropriate to choose areas with mild climate, sufficient light, abundant rainfall, more uniform precipitation in the growing season, high air humidity, and less frost and frost damage in the morning and evening.

2. Soil: the growing soil of kiwifruit should be sandy soil with deep and fertile soil, good air permeability, underground water level below 1 meter, high content of organic matter and slightly acidic soil with PH 5.5-6.5. Strong acid or alkaline soil should be improved before cultivation.

3. Lighting: kiwifruit likes the light and is afraid of the sun, and has a strong ability to make use of astigmatism. Even if it is twining and growing on a big tree, there is no problem, but it cannot be too concealed. If there is a serious lack of light, the branches will die. Popular saying is that they like the sun but are afraid of high temperature.

4. Temperature: kiwifruit likes warmth, in fact, temperature is the main factor that limits the distribution, growth and development of kiwifruit. Each species has a suitable temperature range, beyond which it will grow poorly or cannot survive, but most species require a warm and humid climate.

5. Fertilizer: kiwifruit likes fertilizer. Once lack of inorganic nutrients, kiwifruit shows yellowing, leaflet, stop growing and other phenomena, but fleshy root system is also very sensitive to soil salt concentration. In production, a small amount of multiple fertilizer application is required to meet the fertilizer demand without fertilizer damage.

6. Moisture: kiwifruit likes water and is afraid of waterlogging, but the root system of kiwifruit is fleshy, and its respiration is strong, which requires more oxygen content in the soil, that is, to have the necessary soil air permeability, so according to the relationship between the growth and decline of soil water and air, you can't water too much.

How to plant kiwifruit seeds?

1. Seed collection: the ripe fruit is collected from the first ten days of September to the first and middle of October. After ripening and softening, the fruit is extruded together with the seeds, rubbed in a gauze bag to separate the seeds from the pulp, and washed repeatedly with clean water. Leave the washed seeds in the shade to dry indoors.

2. Sand storage treatment: soak the seeds in 40-50 ℃ warm water for 2 hours, then soak them in cold water for one day and night, and then sow seeds in sand for 50-60 days. Kiwifruit seeds are afraid of dry and wet in the process of sand storage, so they should be checked and turned frequently to prevent mildew.

2. Sowing at the right time: the sowing time of kiwifruit is generally from late March to early April. The soil on the seedling bed is fine, and then watered through with slow water. After water infiltration, the seeds are sown on the seedbed, covered with a layer of fine sand, and then gently flattened. Cover with grass to maintain humidity.

3. Nursery bed management: after kiwifruit sowing, we should pay attention to keep the soil moist by spraying water frequently. After emergence, the seedlings should be ventilated and refined to prevent lodging. When the seedlings grow to 2-3 true leaves and 4-5 true leaves, the seedlings are divided into different stages, and the seedlings can be transplanted.

High-yielding planting techniques of kiwifruit

1. Garden selection: kiwifruit root system is fragile, afraid of waterlogging and high temperature and drought, and new shoots are afraid of strong wind and cold in late spring or low temperature, so it is suitable to plant in subalpine areas. the garden should be built in places with deep soil, fertile soil, loose texture, good drainage and convenient transportation.

2. Seed selection and seedling raising: there are many kiwifruit varieties, such as Hongyang, Qingcheng 1, Chuanyi 2, Miliang 1 and so on. Suitable varieties should be selected according to geographical environment. There are two main seedling raising methods: rootstock seedling cultivation and grafted seedling cultivation, and their seedling raising methods are different.

3. Seedling planting: kiwifruit was planted from October to the end of February next year. The seedlings with disease-free, insect-free, robust growth and well-developed root system were selected. The ratio of female to male was 10:1. When planting, the root system was separated and evenly spread on the soil pile, and the root system was tilted straight. after the root system is put, the fine soil is filled.

4. Erection and cable drawing: kiwifruit adopts T-shaped frame, hedge frame, tripod frame, greenhouse frame and so on, mostly using flat-top greenhouse frame, and can use the original small diameter tree as living pile on the spot, plus some replaceable bamboo wood dirt, and concrete piles are used in key parts.

5. Topdressing and watering: 2.5 kg of fruit wood fertilizer can be applied to each plant in the pit before kiwifruit planting, and a small amount of multiple fertilization is used for young trees. After that, it was generally fertilized three times a year, base fertilizer once, topdressing twice, mainly available, and the value of nitrogen, phosphorus and potassium was 4:2:1.

6. Pruning and fruit thinning: kiwifruit is divided into winter pruning, summer pruning and male plant pruning before pruning. Winter shearing is carried out from defoliation to one month before sprouting in early spring, and summer pruning is mainly carried out from mid-May to early July. Fruit thinning is generally carried out one month after flowering, leaving the middle fruit and edge fruit.

7. Timely harvest: harvesting kiwifruit too early or too late will affect the quality and flavor of kiwifruit. Harvesting should be carried out in sunny days without wind, but not in rainy days, after rain and in the morning when the dew is not dry. It is better to pick kiwifruit when the temperature does not rise before 10:00 in the morning.

Control techniques of kiwifruit diseases and insect pests

1. Mature rot

[harmful symptoms] when kiwifruit is ripe, there are similar thumb indentation spots on one side of the harvested fruit, the edge of the spot is dark green or waterlogged, and there is often milky cone rot in the middle, which can be expanded to the middle of the pulp and even the whole fruit rot in a few days.

[control method] from two weeks after flowering to the fruit expansion period, the canopy was sprayed with 50% carbendazim 800x solution or 1RV 0.5-200-fold Bordeaux solution, or 1000-fold topazine wettable powder 2 times twice, with an interval of about 20 days.
