Embodiment 1

[0031] The test location is Baoan Town, Chongzuo City, Guangxi. The test sugarcane variety is Guitang 40, the planting density is 4800 buds per mu, and the planting cycle is 245 days. The planting method is as follows:

[0032] (1) Soil preparation: Use a subsoiler to subsoil and crush the soil half a month in advance. The depth of the subsoil is 50-60cm, and lime and biochar are turned into the soil, and the pH of the planting site is adjusted to 7.0 about. It can be sprayed at the same time to prevent insects and weeds to further kill insects and prevent weeds, and improve the planting environment of sugarcane. Further, the weight ratio of the lime to the biochar is 1:2. Described biochar is the biochar purchased on the market. Lime kills pests in the soil and adjusts the pH of the soil. As a soil conditioner, biochar can improve soil indicators, enhance soil water holding capacity and air permeability, increase soil porosity, and benefit the growth of sugarcane roots in ...

Embodiment 2

[0051] The test location of this example is Quli Town, Fusui County, Chongzuo City, Guangxi. The test sugarcane variety is Guitang 42, the planting density is 5000 buds per mu, and the planting cycle is 258 days.

[0052] The planting method is as follows:

[0053] (1) Soil preparation: use a subsoiler to subsoil and crush the soil to a depth of 50-60cm, and turn lime and biochar into the soil to adjust the pH of the planting site to about 7.0. The weight ratio of the lime and biochar is 2:3. The biochar is biochar loaded with humic acid. Humic acid solution is sprayed into the purchased biochar, stirred, dried and left to stand to obtain humic acid-loaded biochar. Of course, other existing methods can also be used to realize the modification of biochar.

[0054] (2) Seed stem treatment: select healthy sugarcane seed stems, first soak the healthy sugarcane seed stems in warm water at 55°C for 25 minutes, then put them into nitrogen-fixing bacteria solution for 60 minutes, a...

Embodiment 3

[0070] The test location of this example is Baiji Township, Suining District, Nanning City, Guangxi. The test sugarcane variety is Guitang 46, the planting density is 6000 buds per mu, and the planting cycle is 262 days. The planting method is as follows:

[0071] (1) Soil preparation: Use a subsoiler to subsoil the soil to a depth of 50-60cm, turn lime and biochar into the soil, and adjust the pH of the planting site to about 7.2. The weight ratio of the lime to the biochar is 1:3. The biochar is purchased modified biochar.

[0072] (2) Seed stem treatment: select healthy sugarcane seed stems, first soak the healthy sugarcane seed stems in warm water at 55°C for 25 minutes, then put them into nitrogen-fixing bacteria solution for 60 minutes, and drain the water for later use. The nitrogen-fixing bacteria in the nitrogen-fixing bacteria solution are two nitrogen-fixing bacteria strains A01 and L03 isolated from the root system of sugarcane variety Guitang No. 28, and A01 and...

Abstract

The invention relates to the technical field of sugarcane planting, and particularly discloses a sugarcane weight-losing and efficiency-improving planting method which comprises the following steps: (1) soil preparation; (2) seed stem treatment; (3) sugarcane planting; (4) field management; (5) harvesting. According to the planting method, a proper amount of nitrogen fertilizer is intensively applied in the early growth stage of sugarcane, phosphorus-potassium fertilizer and microelement fertilizer are cooperatively applied, the PH value of soil and water supply are adjusted, meanwhile, nitrogen-fixing bacteria liquid is adopted for soaking seeds, compound microorganism fertilizer is adopted as base fertilizer, early-stage growth of sugarcane can be accelerated, sugarcane plants can form strong root systems and robust overground stem leaves, and the yield of sugarcane is increased. Fertilization is not needed in the large growth period (elongation period) after the sugarcane is closed, biological nitrogen fixation of the sugarcane is promoted, nitrogen nutrition needed by growth of the sugarcane is provided, and compared with a traditional'three-attack and one-supplement 'fertilization method, implementation of the fertilizer can be effectively saved, the nitrogen fertilizer utilization rate is increased, environmental pollution is reduced, and sustainable development of the sugarcane industry is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a sugarcane weight-loss and efficiency-enhancing planting method. Background technique [0002] Sugarcane is an important sugar and energy crop. Guangxi is the second largest sugar-producing province (region) in the world. The sugarcane cultivation area accounts for more than 60% of the country's total, and nitrogen fertilizer input is about 930 million yuan per year. A large amount of nitrogen fertilizer input increases the cost of sugarcane production, reduces the benefits of sugarcane production, and has a serious negative impact on the ecological environment. In addition to applying basal fertilizer, sugarcane fertilization method also implements the topdressing method of "three attacks and one supplement", that is, according to the nitrogen demand in different growth stages, a small amount of nitrogen fertilizer (5-10%) is applied at the seedling st...
