Embodiment 1

[0032] Example 1 Competition Test of Tall Fescue and Guayule

[0033] The experiment was carried out in the net room of the Institute of Plant Protection, Shandong Academy of Agricultural Sciences. The type of substitute plant is tall fescue, and the object of competition is guayule. The diameter of the upper mouth of the test flower pot is 25 cm, and the height is 20 mm. The soil is the topsoil of the farmland, which is a slightly alkaline loam, and the organic matter content is 30.9 g / Kg. Sowing on April 5, 2013, the recommended planting density of tall fescue is 300 kg / ha, the planting depth is 1 cm, guayule is set at 0, 2, 4, 8, 16, 32, 64 plants / pot, and covered with soil 1-2 mm, appropriate amount of multi-sow when sowing, wait for guayule 5-leaf stage to set seedlings to the planned number of plants. Fertilizers were not applied throughout the growth period of the tested plants. On August 15, 2013, the above-ground parts of guayule and tall fescue of each treatment...

Embodiment 2

[0037] Example 2 Field experiment on tall fescue control guayule (April)

[0038] The experiment was carried out in Shizilu Town, Junan County, Shandong Province.

[0039]The experimental site is an abandoned yard with flat terrain, no crops are planted, and the density of guayule is very high every year. Before the site preparation, a large number of dried guayule plants were distributed on the ground, and some guayule seedlings began to be unearthed. The density of unearthed guayule seedlings was very high, up to 100 plants / ㎡. Sowing time is April 24, 2014. First cut off the dried guayule plants of the previous year on the ground, and then sow tall fescue after shallow rotation. The sowing rate is 300 kg / ha; the thickness of the covering soil after sowing is 1-3 cm. When the tall fescue grows to 20 cm, use a herbicide to remove broad-leaved weeds once (the herbicide used is Tribenuron-methyl or 2-M-4-Chlorophyll, and the dosage is the conventional dosage). Whenever the ...

Embodiment 3

[0043] Example 3 Field experiment on tall fescue control guayule (June)

[0044] The test was conducted in Junan County, Shandong Province on June 12, 2014.

[0045] The experimental site is an abandoned yard with flat terrain, no crops are planted, and the density of guayule is very high every year. Before site preparation, a large number of guayules grow vigorously on the ground, with a plant height of 20-60 cm, and visual inspection can reach 100 plants / ㎡. The sowing time of tall fescue was June 12, 2014. Pull out the guayule plants that have been unearthed and last year's dried plants, and then sow the seeds after shallow rotation. The sowing rate is 300 kg / ha; the thickness of the covering soil after sowing is 1-3 cm. When tall fescue grows to 20 centimeters, herbicide weeding 1 time (used herbicide and consumption are the same as embodiment 2). Mow whenever tall fescue grows to 20 cm tall; in summer, it grows fast, mow once every other week, and the stubble height i...

Abstract

The invention relates to a method for replacing and controlling guayule with tall fescue, and belongs to the technical field of plant control. According to the method for replacing and controlling guayule with tall fescue, tall fescue seeds are sown from April to May or from August to October on land where guayule grows. As proved by years of experimental research, tall fescue can replace and control guayule; moreover, guayule can be continuously controlled, and the control effect can be maintained for 3-5 years under a good scientific management condition. Moreover, soil and water conservation can be facilitated by replacing and controlling guayule with tall fescue. Furthermore, tall fescue has a very good economical utilization value, and can be taken as pasture for feeding livestock, so that sufficient high-quality feed is provided for the development of animal husbandry; tall fescue can be used for greening lawns, and plays a good role in beautifying the environment. In other words, soil and water conservation can be facilitated while the guayule is replaced and controlled, and the economic output value of soil is increased.

Description

technical field [0001] The invention relates to a method for replacing guayule by using tall fescue to control guayule, and belongs to the technical field of plant control. Background technique [0002] Guayule ( Parthenium hysterophorus L.), belonging to the genus Guayule in the Asteraceae family, is an exotic harmful weed native to the Americas. The weed is currently distributed in 30 countries and has become one of the major weeds in eastern Australia and India. Guayule has strong reproductive ability, and the number of seeds per plant can reach 2000-45000. It has good adaptability to various environments, and the shedding and dormancy of guayule seeds make it suitable for soil in the soil. Strong stability and strong adaptability in harsh environments. Guayule can cause 40%-90% loss of crop and pasture yield, and can cause skin allergies and asthma and other diseases to people, livestock and poultry that come into contact with it. Due to its strong reproductive and ad...
