Embodiment 1

[0043] (1) Compost domestic waste first to remove all kinds of wood, plastic, glass, metal and other sundries, then dry it at 105°C to constant weight, and sieve compost with a particle size of 1700nm. Compost with a particle size of 1700nm Pulverize under 24000 rev / mins, and the time is respectively 3min, 2min and 1min, to prepare the rubbish micro-fertilizer of different particle size, with S4800 field emission scanning electron microscope (S4800, JAPAN) micro-fine municipal solid waste compost particle size is respectively 1200nm, 600nm and 300nm. Then it was dried at 105°C to constant weight, and sieved by standard sieves with different apertures to obtain compost with a particle size of 1700nm; compost with a particle size of 1700nm was crushed at 24000 rpm to prepare compost with a particle size of 1200nm, 600nm and 300nm waste micro-fertilizers with different particle sizes;

[0044] Among them, the organic matter content in the compost is 22.00%, and the bulk density ...

Embodiment 2

[0049] Others are the same as Example 1 and then use a plastic pot with a diameter of 7cm and a height of 10cm. In each pot of 180g soil, 3g, 1200nm, 600nm or 300nm of garbage micro-fertilizers are evenly sprinkled on the soil surface, and finally 20g of soil is evenly covered on it; Sow 0.5g of tall fescue in each pot, control the temperature at 26°C, relative humidity at 40%, and the light is natural light penetrating into the room; at the beginning of sowing, water fully to ensure the smooth germination of the seeds and the growth of the seedlings in the early stage, two weeks Afterwards, water according to 65% of the field water capacity, and then weigh and water every one to two days to maintain the stress range, and start to measure each index on the 44th day.

Abstract

The invention relates to a method for improving activity of antioxidant enzyme of festuca arundinacea by using fine domestic garbage compost under drought conditions. In the method, a plastic pot with diameter of 7cm and height of 10cm is used through a pot experiment; and the method comprises the steps of: putting 150g of soil into each pot; sowing 0.5g of lawn plants in each pot; uniformly spreading 3g of municipal domestic garbage fine compost with particle sizes of 1,200nm, 600nm and 300nm on the surface of the soil; uniformly covering 20g of soil on the surface of the soil; controlling the temperature to be between 20 and 26 DEG C, wherein the relative humidity is between 40 and 60 percent, and illumination is natural light transmitting indoors; fully watering the plants in the initial stage of sowing, and watering by weighing every day to every two days according to 55 to 65 percent of water-holding capacity in fields after two weeks so as to maintain the capacity within a stress range; and measuring all the indexes on the 44th day. A result shows that the fine compost protects the festuca arundinacea plant from being damaged by active oxygen radicals, and reduces adverse environmental stresses to the plant caused by drought stresses.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to the reasonable use of composting of municipal domestic garbage. More specifically, it is a method for improving the activity of tall fescue protective enzymes by composting fine domestic waste under drought conditions. Background technique [0002] Lawns play an important role in urban greening, environmental protection and ecological balance. The planting and maintenance of turfgrass requires a lot of water; the large demand for irrigation water makes the maintenance cost of turfgrass extremely high. develop. The traditional water-saving methods of lawns are through the selection of drought-resistant varieties, the economical irrigation amount of lawns and the selection of irrigation methods; water capacity. Jiao Jinchuan et al. studied the effect of potassium fertilizer on the drought resistance of tall fescue, and used the germination rate of tall fescue seed...
