Embodiment 1
[0051] Example 1 Screening and preparation of low temperature resistant corn straw compound decomposing bacteria agent and screening of activator components and ratio
[0052] Experiment location: Laboratory of Jilin Academy of Agricultural Sciences.
[0053] Soil type: Light chernozem, taken from the corn field of Father and Son Village, Zanzi Township, Qian'an County, Songyuan City.
[0057] The soil samples were taken from the corn stalk stack and the ground contact part of Fuzi Village, Zanzi Township, Gan'an County, Songyuan City, Jilin Province, and the strains were isolated according to the soil microbial analysis manual.
[0058] 5g of each soil sample was inserted into 100mL enrichment medium (peptone 5g, yeast extract 5g, cellulose (Xinhua filter paper) 5g, NaCl 5g, CaCO 3 2g, K 2 PO 4 1g, MgSO 4 ·7H 2 O 0.5g, FeSO 4 ·7H 2 O 0.5 mg, MnSO 4 ·...
Embodiment 2
[0129] Example 2 Experiment of corn straw compound decomposing bacteria agent + activator under the condition of degradable film mulching drip irrigation
[0130] Experimental location: Father and Son Village, Zanzi Township, Qian'an County, Songyuan City.
[0131] Test material: the composite decomposing bacteria agent prepared in the 7th point (2) of Example 1.
[0132] The tested variety: Xiangyu 998.
[0133] Experimental design: 3 treatments were set in the experiment, each treatment was repeated 3 times, and the area of the plot was 48m 2 (6m×8m), ridges are built between the plots, a total of 9 plots are arranged completely randomly.
[0134] Treatment 1——control, no plastic film mulching, no drip irrigation, no corn stalk returning;
[0135] Treatment 2 - Drip irrigation under ordinary mulching film, returning corn stalks to the field, compound decomposing bacteria agent + activator without straw;
[0136] Treatment 3 - Drip irrigation under ordinary mulching f...

Abstract
The present invention provides an under-mulch-plastic-film drip irrigation area promoting type corn straw returning-field method. According to the method, the straw composting rate is regulated by using a straw composite decompositionbacterial agent and an excitant and by covering a under-mulch-plastic-film drip irrigationsystem with a degradable mulchplastic film, and according to the growth and development requirement law of corn in the under-mulch-plastic-film drip irrigation area on nutrients, the nutrients required by corn are timely supplemented and the soil fertility is improved so as to achieve the scientific management and the efficient use of the straws. In the prior art, the under-mulch-plastic-film drip irrigation area corn straw returning-field causes the soil microorganism action so as to compete the nutrients with the corn seedlings, such that the problems of corn seedling weakening, corn seedling death and yield reducing are caused. With the method of the present invention, the problems in the prior art are solved, the rural environment is improved, and the technical difficulty of the under-mulch-plastic-film drip irrigation area corn straw returning-field is broken through.
Description
technical field [0001] The invention belongs to the field of agriculture. Specifically, the invention relates to a method for returning corn stalks to fields in semi-arid drip irrigation areas. Background technique [0002] The seasonal, concentrated, and widespread burning of crop straw is one of the main reasons for the frequent occurrence of smog in Northeast China. Corn is the largest crop in the world and also the largest crop in my country. Jilin Province is an important commodity grain production base in my country, and corn has long occupied a dominant position. At present, the sown area of corn in Jilin Province has reached 57 million mu, and the annual output of corn stalks has reached 40 million tons. More than 50% of the corn stalks have been discarded or burned, causing problems such as deterioration of the agricultural ecological environment and air pollution. [0003] In corn production, there is a problem of "difficulty returning straw to the field". The...
