What are the latest planting conditions of kiwifruit?

Kiwifruit likes cool and humid planting conditions, afraid of drought, waterlogging and wind. Hardy, not resistant to early and late spring frost, planting time from late autumn to early spring, late October in autumn and late February in spring, kiwifruit is harvested from mid-September to mid-October. Let's take a look at the necessary conditions for kiwifruit planting.

Planting conditions of kiwifruit

It is understood that at present, most of the cultivated varieties are delicious kiwifruit and Chinese kiwifruit, which mainly originated in the central and southwestern and central and southeastern regions of China. In the later process of cultivation diffusion, it was found that it could be cultivated from Beijing to Hainan, from Yunnan, Guizhou, Sichuan to Taiwan.

1. Lighting conditions

First of all, I would like to talk about the light and fear the sun. If you are a careful person and close to the mountains with wild kiwifruit, you will find that the kiwifruit in the mountain basically grows on shady or semi-shady slopes, or on the riverside, why, because of fear of the sun, kiwifruit plants have a very strong ability to make use of astigmatism, even if they are entangled and attached to a big tree, there is no problem, but it can not be too hidden, if there is a serious lack of light, it will die. This is why reasonable row spacing is emphasized in production, and why kiwifruit row spacing is set at 5: 5 or 5: 6 in New Zealand. Is to make full use of the habit of kiwifruit, to a certain extent, their kiwifruit has become the first in the world. Popularly speaking, it is like sunshine but afraid of high temperature.

2. Precipitation conditions

In addition, the main reason that kiwifruit likes water and is afraid of waterlogging is that kiwifruit is broad-leaved fruit trees, especially in summer, and the water demand is relatively large, so it is generally required that the soil water content should be maintained at 70% in June, July and August, but at the same time, the root system of kiwifruit is fleshy root, and its respiration is strong, which requires more oxygen content of the soil, that is, it is necessary to have the necessary soil air permeability. Therefore, according to the relationship between the growth and decline of soil water and gas, it should not be watered too much. This is a pair of contradictory unity. What should we do? Therefore, it is necessary to grow grass on the ground, increase the application of organic fertilizer, strengthen the soil water storage capacity, and emphasize the scientific water use principle of soil moisture conservation first and watering irrigation second. In many orchards, a large number of dead trees in summer and autumn for unknown reasons are actually watered, soaked and drowned. Kiwifruit trees will never die of drought, only by waterlogging. Many fruit growers have the experience that if it rains continuously in summer, or if it rains again after watering the land, once the weather clears up, the temperature picks up quickly, and many kiwifruit trees immediately wither (commonly known as the next morning by fruit farmers), and if they are not dealt with in time, the trees will soon die. This is a typical water-loving fear of waterlogging.

3. Fertilization management

Finally, it is said that kiwifruit is fond of fertilizer and afraid of burning, and its urgent demand for fertilizer is determined by its growth and strong growth potential. Coupled with the predatory work psychology of highlighting yield in production, kiwifruit shows yellowing, leaflet, stopping growth and other phenomena once it lacks inorganic nutrients, so kiwifruit is sensitive to fertilizer, but fleshy roots are also sensitive to soil salt concentration (especially continuous high temperature and drought). Thus forming a new contradiction to three-dimensional, in view of this, production requires that the fertilization of kiwifruit must grasp the principle of far scattered light, that is, a small amount of multiple fertilizer application method, that is, it can meet the fertilizer demand without fertilizer damage, which is the kiwifruit like fertilizer and afraid of burning.

4. Temperature condition

Temperature is the main factor that limits the distribution, growth and development of kiwifruit. Each species has a suitable temperature range, beyond which the growth is poor or can not survive. Most species of kiwifruit require warm and humid climate, that is, subtropical or temperate humid and semi-humid climate, mainly distributed in the vast area of 1834 degrees north latitude. The annual average temperature is about 11.3-16.9 ℃, the extreme maximum temperature is 42.6 ℃, the extreme minimum temperature is about-20.3 ℃, the effective accumulated temperature over 10 ℃ is 4500-5200 ℃, and the frost-free period is 160-270 days.

5. Other conditions

Kiwifruit cultivation not only considers the natural environment, but also considers the local social, economic, traffic, microclimate and site environmental conditions. Generally speaking, there are good public order, sufficient investment, convenient transportation, flat land, fertile soil, convenient drainage and irrigation, sufficient light and mild climate. The plots with non-tuyere and hail lines are all ideal garden sites.

Main producing areas of kiwifruit planting

China is the primary center of kiwifruit, and the world kiwifruit originates in China, especially in the Qinling Mountains of Guanzhong, Shaanxi Province; kiwifruit is born on the edge of hillside forests or shrubs, and is cultivated in some gardens. China's Shaanxi, Sichuan, Henan and other areas north of the Yangtze River basin are distributed. Our seven major kiwifruit producing areas are:

1. Qinling Mountain area, Shaanxi Province (mainly Zhouzhi County, Xi'an City, the hometown of kiwifruit in China and its adjacent Huxian County, Baoji Mei County and Wugong County, Xianyang City).

2. Dabie Mountains, Funiu Mountain and Tongbai Mountain in Nanyang City, Henan Province, and Tiantai Mountain in Huanggang City, Hubei Province.

3. Guizhou Plateau and the west of Hunan Province.

4. Heping County, Heyuan, Guangdong.

5. The northwest of Sichuan Province and the southwest of Hubei Province.

6. Jiangshan City, Zhejiang Province.

7. Fengxin County, Jiangxi Province.

8. Shaanxi Province is the largest kiwifruit growing province in China, mainly distributed in Zhouzhi County, Huxian County, Baoji City, Mei County, Xianyang City.

Planting risk of kiwifruit

1. The one-time investment of kiwifruit is relatively large, and the income period needs to be 2 years later, especially in the young tree period, otherwise the expected goal will not be achieved.

2. Kiwifruit belongs to fleshy root system, which is not only afraid of dryness, but also afraid of soiling, which is easy to cause dry and soiled death, drought and drainage can not be ignored.
