Technical Field
The invention belongs to the technical field of agricultural cultivation, and particularly relates to a light and simple sugarcane cultivation management method for full-coverage returning and rapid decomposition of sugarcane leaves.
Background
Sugarcane is the most important sugar crop in China, and the average annual planting area in recent years is about 120 ten thousand hm2Annual raw material cane is about 1 hundred million tons. The residual sugarcane leaf resources after the sugarcane is harvested are very rich and generally account for 12% -20% of the sugarcane stem yield. N, P in residual sugarcane leaves2O5、K2The content of O nutrient is about 1.5%, 0.26% and 2.02%. In addition, the sugarcane leaves also contain a large amount of trace elements, and the sugarcane leaves are an available organic fertilizer source. The full utilization of the sugarcane leaves is beneficial to improving the soil structure of the sugarcane garden, promoting the nutrient cyclic utilization of the sugarcane-soil system and optimizing the ecological environment of the sugarcane garden.
At present, in order to not influence the mechanical tillage operation, the conventional treatment mode of residual sugarcane leaves is to burn the residual sugarcane leaves on the spot and then carry out field management such as fertilization and ridging. The burning of the sugarcane leaves not only causes the loss of the nutrient of the sugarcane leaves and the environmental pollution, but also causes fire and traffic accidents, threatens the problems of human health and the like, and is not beneficial to the sustainable development of the sugarcane.
The sugarcane leaves are returned to the field, so that the field cultivation can be reduced, the soil moisture is kept, the soil erosion is reduced, the soil fertility is improved, and the organic matter content of a cultivated layer and the soil microbial activity are increased. Inhibiting the growth of weeds, improving the soil structure, avoiding the soil degradation and stabilizing the yield of the sugarcane, and is an environment-friendly sugarcane production technology. But in actual operation, the nutrient management difficulty is high, most of applied fertilizer is absorbed by sugarcane leaves, and the utilization rate of the fertilizer is low; the natural decomposition speed of the sugarcane leaves is low, and the sugarcane leaves compete for fertilizer with the sugarcane in the fertilizer requiring and vigorous growth period, so that the yield is reduced; the natural decomposition of the sugarcane leaves takes long time to affect the field management in the next season; the sugarcane leaves returned to the field have a large number of harmful organisms, so that the problems of serious diseases and pests, low yield and the like of the sugarcane are caused.
Chinese patent application CN201310551039.8 discloses a method for recycling sugarcane leaves, wherein after the sugarcane is harvested, the sugarcane leaves are cleaned within 1 week, the sugarcane leaves are collectively stacked between sugarcane planting rows, waste alcohol liquid is uniformly sprayed on the sugarcane leaves according to the amount of 4.5-5.5 tons per mu, and a mulching film is covered on a sugarcane pocket.
Disclosure of Invention
The invention aims to solve the problems that the fertilizer application difficulty is high, the times are many, the utilization rate is low, the natural decomposition speed of the sugarcane leaves is slow, the residual sugarcane leaves influence the cultivation, the management labor is more, the long-time decomposition of the sugarcane leaves and the growth of the sugarcane compete for nutrients, the plant diseases and insect pests are serious and the like in the prior art of returning the sugarcane leaves to the field; the simple cultivation and management method for the sugarcane has the advantages that the fertilizing steps can be reduced, labor is saved, the decomposition of the sugarcane leaves can be accelerated, old and residual sugarcane leaves are fully utilized to continuously provide nutrients for the growth process of the sugarcane, the soil fertility is improved, the using amount of chemical fertilizers is reduced, and the simple cultivation and management method has important significance for improving the income of sugarcane farmers and guaranteeing the sustainable and healthy development of sugarcane industry in China.
The invention relates to a light and simple cultivation management method for rapidly decomposing sugarcane by fully covering sugarcane leaves, returning the sugarcane leaves to the field, which comprises the following steps:
a. after the sugarcane in the previous season is cut and harvested, uniformly and comprehensively covering the sugarcane leaves in the whole sugarcane field;
b. spraying modified molasses alcohol residual liquid in the whole field, wherein the spraying amount is 4-6 tons per mu;
the modified molasses alcohol raffinate is prepared by taking molasses alcohol raffinate obtained after producing alcohol through fermenting cane molasses as a raw material, adding one or more of urea, urea ammonium nitrate, diammonium phosphate, ammonium polyphosphate and ammonia water, and blending to obtain nitrogen, phosphorus and potassium elements N, P2O5:K2The weight ratio of O to the modified molasses alcohol raffinate is 1.2-1.5: 0.6-0.8: 1-1.2;
c. spraying a sugarcane leaf decay compound microbial inoculum, wherein the spraying amount is 2-4 liters per mu;
the sugarcane top decomposition complex microbial inoculum comprises the following active bacteria in the following composition and quantity ratio: trichoderma harzianum, Trichoderma viride, Aspergillus niger and Bacillus subtilis in a ratio of 4-5: 1.5-2.5;
d. and spraying an insecticide at the later stage of the sugarcane growth and tillering stage.
Preferably, the nitrogen phosphorus potassium elements N are P in the modified molasses alcohol residual liquid2O5:K2The weight ratio of O is 1.2:0.6: 1.
Preferably, the pH of the modified molasses alcohol residual liquid is adjusted to be 5.2-6.2 by using one or two of magnesium oxide and quicklime.
More preferably, the pH is 5.6.
Preferably, the composition and the quantity ratio of active bacteria contained in the sugarcane top fast decomposition complex microbial inoculum are as follows: trichoderma harzianum, Trichoderma viride, Aspergillus niger and Bacillus subtilis are 4.5:4.5:2: 2.
Preferably, the time for spraying the modified molasses alcohol residual liquid in the whole field is within 10 days after the sugarcane leaves are covered in the whole field.
Preferably, in the step d, the insecticide is sprayed once at the later stage of the sugarcane growth tillering stage, the insecticide is applied after being diluted by 50 times by 20% chlorantraniliprole, the application amount per mu is 1L, and then any insecticide is not sprayed until the sugarcane is harvested.
Preferably, the modified molasses alcohol residual liquid is sprayed in the whole field, so that the water content of sugarcane leaves covering the sugarcane field is adjusted to be 60% -70%, and the carbon-nitrogen ratio is adjusted to be 20-30: 1. The water content and the carbon-nitrogen ratio are calculated according to the weight ratio.
More preferably, the modified molasses alcohol residual liquid is sprayed in the whole field, so that the water content of sugarcane leaves covered on the sugarcane field is adjusted to 65%, and the carbon-nitrogen ratio is adjusted to 25: 1. The water content and the carbon-nitrogen ratio are calculated according to the weight ratio.
