Description
Technical Field
The application relates to the technical field of gardening and planting, in particular to a method for modifying a northern arid region field shrub type leisure sightseeing garden of Chinese roses.
Background
The Chinese rose, called "queen of flower", belongs to the Rosaceae family and is one of the ten famous flowers in China. The Chinese rose has extremely high ornamental value due to large flower quantity, multiple flower colors and long flowering period, is luxuriant in branches and leaves, cold-resistant, drought-resistant, strong in adaptability and easy to manage, and becomes an important landscape flower in all parts of the country, particularly in arid regions in the north. A great deal of research is carried out for water and fertilizer regulation of different varieties of Chinese roses for decades, and Chinese rose culture substrate research (Hu Chengxian and the like, 2022) and N, P, K nutrition regulation (Wang Huarong and the like, 2012; liu Zhiyuan and the like, 2022; sun Yating and the like, 2017), water soluble fertilizer regulation (Ren Zhongxiu and the like, 2011), leaf fertilizer (Wang Yangyang and the like, 2022) slow release fertilizer, water retention agent (Liu Chenhao and the like, 2017), organic fertilizer (once fierce and the like, 2021; yang Yonghua and the like, 2014) and earthworm cast (Li Qiuyue and the like, 2017) are carried out different treatments, and the measures effectively promote the growth and flowering of the Chinese roses to different degrees.
Research shows that the horticultural plant can fully absorb nutrients in soil through the root system, and then the growth quality of the horticultural plant is influenced, including vegetative growth and reproductive growth, so that the growth and development quality of the horticultural plant can be improved by regulating and controlling the growth space and the growth environmental factors of the root system of the horticultural plant. At present, the root zone limiting technology of fruit trees is applied more frequently, and the common method mainly comprises (1) container limiting and more application in potted plants; (2) Nutrient and water limitation is mainly realized by utilizing a drip irrigation mode on horticultural plants; (3) The underground soil is blocked and limited, and the underground growth space of the plant root system is limited by using hard materials with higher density, such as stones, slates and the like; (4) The method is characterized by comprising the following steps of mechanical and manual treatment and culture medium limitation, wherein the mechanical and manual treatment limitation mainly means that workers use modes of cutting, straightening, knotting root systems, coiling roots and the like to limit the growth and development space of the root systems of the horticultural plants, and the culture medium mode is to limit the growth and development space of the plants through solution. These methods have been widely applied to perennial fruit trees such as apples, grapes, persimmon trees, peach trees, medlar and the like, and have also achieved good results in practice (Yang Hongjiang et al, 2002; shen Hailin et al, 2022; li Dongmei et al, 2022; lv Yingzhong et al, 2020; pang Yujie et al, 2018; he Xinru et al, 2017; wang Jie et al, 2016). The root zone limiting technology is only used on flowers and plants and is only a container limiting technology. Pang Yujie et al (2022) use root control to study the effect of carbon-to-nitrogen ratio and ABA content in the differentiation process of peach blossom buds. However, in flower and garden plants, liu Xiaojuan and the like (2015 and 2016) mainly utilize a potted plant region limiting technology to influence carbon metabolism of flowering organs of peonies, zhang Bowen and the like (2018) research influence of root region limitation on growth of parthenocissus tricuspidata, and Shen Yajun and the like (2022) research root-cap relation and photosynthetic characteristics of hydrangea by utilizing large, medium and small containers.
Research aiming at the growth of the Chinese rose emphasizes regulating the vegetative growth or reproductive growth of the Chinese rose, or only considering the vegetative growth or reproductive growth of the Chinese rose and considering no root growth of the Chinese rose. In reality, the Chinese rose is used as a shrub for many years, the growth of the Chinese rose comprises vegetative growth, reproductive growth and root growth, and the sustainable improvement of the quality of the Chinese rose can be ensured only if the three growths are coordinated. In view of the adverse factors of compact soil layer, low organic matter content, unbalanced nutrients, poor soil water and fertilizer retention capacity and the like existing in the field shrub type Chinese roses planted in the field of the leisure sightseeing garden in the mountainous area of the arid area in the north, the drought condition occurs sometimes particularly in spring, and the landscape quality of the Chinese roses in different ornamental periods is seriously threatened. Along with the increase of the planting age, in the cultivation and production process of big Tian Guanmu China rose in a leisure sightseeing garden in a north arid region, due to poor conditions of land standing and poor water and fertilizer management, the flower quantity is small, the flower color is light, the number of petals is small, the diameter of flowers is small, the leaves are yellow, the growth vigor is thin and weak and the like, the ornamental value is greatly reduced, and the income of the leisure garden is reduced to a great extent. Therefore, the flowering quality of Chinese rose flowers needs to be improved urgently. At present, a technology for improving flowering quality by combining Chinese rose root region limitation and nutrition regulation and control in different ornamental periods in a leisure sightseeing garden in a northern arid region is lacked.
Patent application ZL200610096355 provides a method for manufacturing plant pots by composting and decomposing straws. But the container root zone limitation is not applicable to the reformation of the field flower agricultural sightseeing garden. As is well known, the agricultural sightseeing garden needs mature landscape (only mature landscape can attract tourists), if a root zone limitation measure of a container (compost is decomposed by straws to make a plant pot) is adopted, on one hand, a large amount of manpower is needed to manually dig out the perennial Chinese roses and cultivate the Chinese roses into the corresponding containers, and on the other hand, the planting in the containers can also damage the original field irrigation facilities, so that the later-period management and protection cost is further increased. Therefore, the container is not suitable for the China rose garden in the leisure sightseeing garden in the northern arid region because of limiting the root.
At present, adverse factors such as compact soil layer, low organic matter content, unbalanced nutrients, poor soil water and fertilizer conservation capability and the like exist in field shrub type Chinese roses planted in mountainous area leisure sightseeing gardens of northern arid areas, drought conditions occur sometimes especially in spring, and the landscape quality of the Chinese roses in different ornamental periods is seriously threatened. Along with the increase of the planting age, in the cultivation and production process of big Tian Guanmu China rose in a leisure sightseeing garden in a north arid region, due to poor conditions of land standing and poor water and fertilizer management, the flower quantity is small, the flower color is light, the number of petals is small, the diameter of flowers is small, the leaves are yellow, the growth vigor is thin and weak and the like, the ornamental value is greatly reduced, and the income of the leisure garden is reduced to a great extent. Therefore, the flowering quality of the Chinese rose flowers needs to be improved urgently. Studies on the growth of roses have mostly focused on regulating the vegetative growth or reproductive growth of roses, or on both, and have not considered the growth of the root system of roses. At present, a technology for improving flowering quality by combining Chinese rose root region limitation and nutrition regulation and control in different viewing periods in a leisure sightseeing garden in a northern arid region is lacked.
The verbena is relatively wide in adaptability, a purple landscape is built by large-area planting in an agricultural sightseeing garden in an arid region, the biomass of the overground part of the verbena is large, the dry matter of one verbena can reach 3-4 kg according to field investigation, and researches of Zhang Zhipeng and the like (2022) show that the verbena has high verbena glycoside content in spica, leaves and lateral branches; the content of roots and main stems is low. The abandoned verbena branch is mainly composed of withered leaves and lateral branches, so researches on 11 plants such as verbena and groundsel (2022) which contain low verbena glycoside, luo Jianmei and the like find that the bacteriostatic activity and bacteriostatic rate of different degrees are 9.70-26.12 percent. Therefore, a method for reasonably utilizing the verbena branch and stalk wastes in the leisure park is needed to be explored.
