Embodiment 1

[0033] A pomegranate cold house cultivation method for preventing cold and preventing diseases and insect pests, the specific steps are as follows:

[0034] (1) Garden building

[0035] In the first ten days of April, select high-quality pomegranate seedlings with a ground diameter of 2 to 3 cm, and plant them on the plains with a row spacing of 1.5×3 m. 2 Plant 148 plants.

[0036] (2) Plastic pruning

[0037] After planting, set the stem at a distance of 80-100 cm from the ground. When the new shoot is 25-30 cm long, select the central trunk, remove competing branches, and leave 3-4 main branches. When the main branch grows to 40-50cm, twist the tip 110° to below the level so that the flower buds can differentiate and form fruiting branches. When the new lateral branches from the central trunk grow to 30-40 cm, the tips are twisted 110° to below the horizontal. The central stem binds the bamboo poles to prevent the tree from falling. After 2 years, the tree body will ta...

Embodiment 2

[0044] A pomegranate cold shed cultivation method for preventing cold and preventing damage by diseases and insect pests, as described in embodiment 1, the difference is:

[0045] Step (3): In the Shandong area, close the shed after the leaves of the trees fall in the first ten days of November. The cold shed support adopts hot-dip galvanized pipe: the height of the center of the shed is 3.7m, the width is 8.4m, the shoulder height is 2m, and the length depends on the ground. After the bracket is set up, cover it with plastic film. One lamination groove is left on the side of the shed 0.8m from the ground to fix the plastic film; one lamination groove is left on the 1.5m above the ground to fix the plastic film; the film rolling machine is connected at 0.8-1.5m for ventilation and cooling. Three rows can be planted in each shed to improve the utilization efficiency of the shed.

experiment example

[0049] After the method of Example 1-2 of the present invention and the method of Comparative Example 1 were subjected to cold protection treatment, the yield per pomegranate plant in the third year was tested, and the temperature in the extremely cold environment was -12°C.

[0050] The impact of the method of the present invention and comparative examples on pomegranate frost damage and yield index is shown in the following table 1,

[0051] Table 1 Effects of cultivation methods on pomegranate frost damage and yield indicators

[0052] project Freezing injury rate (%) Yield per plant (kg) Yield (kg / 667m 2 )

[0053] It can be seen from the above table that the present invention can obviously reduce the freezing damage of pomegranate, and can increase the yield of pomegranate.

Abstract

The invention relates to a pomegranate cold shed cultivation method capable of preventing cold, diseases and pests. The method includes: building a garden; performing trimming; erecting supports to build a shed after leaves of pomegranate trees fall in the first ten days of November and the garden is built, wherein the central height of the shed is 3.5-3.7 m, the width of the shed is 8.4 m, and the shoulder height of the shed is 1.8-2 m, a controllable opening is formed in a side surface of the shed; and opening the controllable opening to perform ventilation in the last ten days of November when the temperature of the shed reach above 0 DEG C in daytime, keeping the temperature of the shed no more than 15 DEG C after ventilation, and closing the controllable opening to preserve heat when the temperature of the shed is 0-3 DEG C at nighttime. The method has a significant anti-cold and anti-freezing effect, can be used all year round, can avoid shed uncovering, can save time and effort, is excellent in disease and insect control effect, is conductive to sustainable development of the pomegranate industry, has many effects, can prevent cold, can keep the pomegranate in a reasonable temperature environment in winter, facilitates ventilation control, can prevent rain, can prevent dehiscent fruits and bad fruits, and can prevent pest and mosquitoes in summer.

Description

technical field [0001] The invention relates to a pomegranate cold house cultivation method for preventing cold and pests, and belongs to the technical field of pesticides. Background technique [0002] Pomegranate (Punica granatum L.) belongs to the deciduous fruit tree of Punicaceae (Punicaceae). It is native to tropical and subtropical regions such as Iran and Afghanistan. The fruit is rich in biologically active substances and has strong health care functions. increasingly favored by consumers. my country's pomegranate has been cultivated for more than 2,000 years, and it is mainly distributed in Shandong, Yunnan, Sichuan, Anhui, Shaanxi, Henan and Xinjiang. Pomegranate likes temperature and is afraid of cold. During the dormancy period in winter, there will be different degrees of freezing damage at around -12°C. It mainly grows on the sunny slopes of the main production areas, and the cultivation of pomegranates in the plains has not yet reached a large scale. From t...
