Problems solved by technology

Under adversity, carbohydrates in plant source leaves will accumulate, such as starch grains will increase in size, which will lead to the obstruction of photosynthesis, that is, the "product inhibition" of photosynthesis, resulting in a decrease in plant photosynthetic rate

Embodiment Construction

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] A high-efficiency calcium-increasing ecological planting method under the corn-peanut intercropping mode mainly adopts field experiments, and sets different calcium application treatments under the peanut single-cropping and corn-peanut intercropping (3:4) planting modes to conduct research. The specific test design, The measurement items and methods are as follows:

[0031] (1) The first choice is to use the dense, high-yield, and compact variety Denghai 605 corn as the test material, and the relatively shade-tolerant, high-yield variety Huayu No. 25 as the test material for peanuts, and select the soil with a replaceable calcium content of less than 200mg / kg plot;

[0032] (2) Set the amount of calcium application (CaO) to 0 kg hm -2 、150 kg hm -2 、300 kg hm -2 and 450 kg hm -2 , the application rate of nitrogen, phosphorus and...

Abstract

The invention discloses a calcium adding efficient ecological planting method in a corn and peanut intercropping mode. According to the method, 'flower cultivating 25' is taken as an experimental material, in corn||peanut 3:4 intercropping and peanut monoculture planting modes, different amounts of added calcium are set for treatment, and the yield of peanuts, the net photosynthetic rate of leavesand differences of the physiological property of the peanuts are studied; the study result shows that by adding calcium suitably, the yield of the peanuts in intercropping and monoculture modes can be further increased conveniently, the yield increasing effect on middle rows in the intercropping mode under the calcium adding premise is significantly higher than that of the monoculture mode, and acalcium fertilizer is applied additionally to increase the net photosynthetic rate of the peanuts, improve the activity of CAT, POD and SOD of peanut leaves in the monoculture and intercropping modes, and reduce the content of MDA of the peanut leaves. It is shown that calcium applying is beneficial for increasing the yield of the peanuts, improving the adaptability of the peanuts to shading, andimproving the photosynthetic production capacity of the peanuts.

Description

technical field [0001] The invention relates to a crop planting method, in particular to a calcium-increasing high-efficiency ecological planting method under the corn-peanut intercropping mode. Background technique [0002] Intercropping is the essence of traditional agriculture in my country. It is to rationally arrange crops with different ecological niches together in the same season to form an efficient community that makes full use of various natural resources, thereby increasing the multiple cropping index and comprehensive land output rate. Intercropping of different types of crops can make full use of natural resources such as fertilizer, water, light, and heat, reduce pests and diseases, and strengthen the service functions of farmland ecosystems, thereby achieving a substantial increase in crop yields and efficient use of resources. Peanut, a leguminous crop, is widely used for intercropping with other crops and economic forests because of its ability to fix nitro...
