Embodiment 1

[0034] Select the area where Tribulus terrestris grows, and randomly delineate a 5m × 5m test plot, with 5 replicates. Sunflowers were planted in the experimental plot by hole sowing. The sowing date was May 8, the seeding rate was 2 seeds per hole, the sowing hole spacing was 30 cm, the row spacing was 40 cm, and the sowing depth was 1 cm. After emergence, the sunflowers were thinned when 1 pair of true leaves were grown, and the seedlings were fixed when 2 pairs of true leaves were grown, and one strong seedling was reserved for each hole. Conventional field management practices were used and no weeding was performed. When the thorn buds of Tribulus terrestris are mature, the growth indicators such as the number of plants, plant height, number of tillers, number of caryopsis (thorn fruits), and biomass are measured and calculated.

[0035] Example

[0036] It is implemented in the same manner as in Example 1, and the difference from Example 1 is shown in Table 1.

Abstract

The invention provides a method for substituting and controlling Tribulus terrestris. The method adopts sunflower to biologically replace Tribulus terrestris. This method has a significant control effect on Tribulus terrestris, which can reduce its occurrence density by 40% to 80%, plant height by 57.2% to 71.7%, tiller number by 70.9% to 100%, and caryopsis number by 87.4%. 100%, the biomass is reduced by 89.2% to 98.9%; the cost of sunflower planting is extremely low, and the planting method is simple and easy to operate. Compared with physical control and chemical control, it can greatly reduce the input of human, material and financial resources; Beneficial species will not cause any harm, which can avoid the threat of chemical control to human health and non-target species; sunflower is an important oil crop and economic crop, which can achieve high economic efficiency while controlling the less flowering Tribulus terrestris value.

Description

technical field [0001] The invention relates to the technical field of biological replacement, in particular to a biological replacement control method of Tribulus terrestris. Background technique [0002] At present, biological invasion has become a global environmental problem. Invasion of alien organisms not only causes economic losses in agriculture, forestry, animal husbandry, fishery, tourism, etc., but also causes the following hazards: serious disturbance and harm to the structure, function and ecological environment of specific ecosystems; Many native species face existential threats and fall into extinction, accelerating biodiversity loss and species extinction; invasive alien organisms can change the composition and structure of food chains or food networks by suppressing or crowding out native species, especially exotic weeds , often lead to the diversity of flora in invasive areas becoming very single, and destroy arable land; invasive alien organisms may also ...
