Problems solved by technology

[0006] At present, there are two main ways to solve the "white pollution" caused by plastics. One is to recycle the used plastics, but this is restricted by the use of plastics, categories, and economics. Generally speaking, recyclable plastics Limited, most of these plastics are made of petroleum, which cannot be degraded in the natural environment after use, and can also resist bacterial erosion, so the recovery rate is low, so it cannot completely and effectively solve the "white pollution" "Secondly, vigorously promote the use of degradable plastics, which is one of the effective ways to solve the problem of "white pollution"
However, most of

Embodiment 1

[0046] (1) Preparation of biocontrol bacteria powder

[0047] A biocontrol fungus Pythium melon and fruit with strong pathogenicity to Liedang was isolated from the naturally dead Liedang plants in Xinjiang. The Pythium melon fruit preserved on the slant was activated on the PDA plate, and the mycelium was collected after the bacterial block was shaken in the PD medium. The collected mycelia of Pythium melon and fruit were placed in 1000 mL of liquid NA medium, and vibrated at a temperature of 28-30° C. and a rotational speed of 180 r / min for 72 hours to obtain a Pythium melon fruit fermentation broth. Centrifuge the fermentation liquid of Pythium melon and fruit at 3600r / min for 30min at room temperature, take the supernatant, mix it with 30g of macroporous resin AmberliteXAD16, shake at 28°C and 160r / min for 4h, and then fill the column. Wash the column with distilled water first, then elute with acetone, and collect the acetone eluate. Concentrate the acetone eluate by ro...

Embodiment 2

[0056] Step (1) preparation of biocontrol bacteria powder and step (2) preparation of polyester biodegradation raw material are the same as in Example 1.

[0057] Step (3) preparation of biodegradable mulch film:

[0058] Increase the biocontrol bacterium powder that contains 4%PVP in the auxiliary agent pipeline 7, wherein biocontrol bacterium powder 3.0Kg, other as the step (3) of embodiment 1;

[0059] 4) The control effect of Liedang

[0060] The polyester biodegradable mulch film prepared above for preventing and controlling parasitic weeds, and common mulch were respectively laid in the fields adjacent to melons and radang; Effects of polyester biodegradable mulch and common mulch on yield of melon. The results showed that there was no significant difference in growth and yield between two melons covered with different plastic films, and the melons were basically not affected. In the second year, the effect of the polyester biodegradable mulch film on the parasitic we...

Embodiment 3

[0062] Step (1) preparation of biocontrol bacteria powder and step (2) preparation of polyester biodegradation raw material are the same as in Example 1.

[0063] Step (3) preparation of biodegradable plastic film

[0064] Increase biocontrol bacterium powder and humic acid containing 4%PVP in the auxiliary agent pipeline 7, wherein each 3.0Kg of biocontrol bacterium powder and humic acid, other as the step (3) of embodiment 1;

[0065](4) The control effect of Liedang

[0066] The above-mentioned polyester biodegradable mulch film for preventing and controlling parasitic weeds, and common mulch were laid separately in the fields with melons and radon; Effects of biodegradable and common mulches on yield of melons. The results showed that there was no significant difference in growth and yield between two melons covered with different plastic films, and the melons were basically not affected. In the second year, the effect of the polyester biodegradable mulch film on the pa...

Abstract

The invention relates to a method of preventing and treating a weed, orobanche coerulescens, through an agricultural bio-degradable mulching film combined with biocontrol bacteria. The method includes the steps of preparing a fermentation liquid of pythium aphanidermatum, performing centrifugal, elution on a column and concentration to the fermentation liquid to prepare a pythium aphanidermatum powder, preparing the bio-degradable mulching film containing the pythium aphanidermatum powder, and paving the mulching film in the field on which crops and the orobanche coerulescens are grown. The method is excellent in preventing and treating effects, avoids pollution caused by chemical agents through the bio-controlling technology, and is more durable in the preventing and treating effects since the synergistic effects of the bio-degradable mulching film is combined.

Description

technical field [0001] The invention relates to a method for preventing and controlling weeds, in particular to a method for preventing and controlling weeds through the combination of agricultural biodegradable plastic film and biocontrol bacteria. Background technique [0002] Xinjiang is the main processing tomato planting and processing base in my country. Cantaloupe is a famous specialty in Xinjiang. In addition, crops such as melon, sunflower, and stevia are important economic crops in Altay, Tacheng and other places, but these crops are without exception. The land was seriously harmed by the root parasitic seed plant Liedang, and caused serious economic losses. When the temperature and humidity are suitable, the seeds will start to germinate and grow small germ tubes when exposed to the stimulation of the host’s root exudates in the soil, and the top of the germ tubes will be adsorbed on the lateral roots of the host to absorb the nutrients and water of the host, that ...
