Embodiment 1

[0020] A planting method of environment-friendly purple corn, is characterized in that, described method comprises the steps:

[0021] (1) Matching substrate: Take phosphorus fertilizer and add it to the substrate composed of peat and vermiculite according to the ratio of 3:2, so that the phosphorus content in the seedling substrate is 150mg / kg;

[0022] (2) Open furrow field: the width of the middle furrow is 2.8m, and the width of both sides is 1.3m respectively. There are aisles and irrigation and drainage ditches between the middle and both sides of the furrow, and the total width of each side aisle and irrigation and drainage ditches 0.5m;

[0023] (3) Seedling raising: plant corn on the middle border with a row spacing of 16cm and a plant-to-plant spacing of 2.4cm, and plant cucumbers on both sides of the border, perpendicular to the aisle, and control the row-to-plant spacing of 0.25×0.2m;

[0024] (4) Seedling management: Spray 3 times diluted Hoagland nutrient soluti...

Embodiment 2

[0027] A planting method of environment-friendly purple corn, is characterized in that, described method comprises the steps:

[0028] (1) Matching substrate: Take phosphorus fertilizer and add it to the substrate composed of peat and vermiculite according to the ratio of 3:2, so that the phosphorus content in the seedling substrate is 170mg / kg;

[0029] (2) Open furrow field: the width of the middle furrow is 2.8m, and the width of both sides is 1.3m respectively. There are aisles and irrigation and drainage ditches between the middle and both sides of the furrow, and the total width of each side aisle and irrigation and drainage ditches 0.5m;

[0030] (3) Seedling raising: plant corn on the middle border with a row spacing of 18cm and a plant-to-plant spacing of 2.6cm, and plant cucumbers on both sides of the border, perpendicular to the aisle, and control the row-to-plant spacing of 0.25×0.2m;

[0031] (4) Seedling management: Spray 5-fold diluted Hoagland nutrient solutio...

Abstract

The invention discloses a planting method of environment-friendly purple corn. The planting method is characterized by including the following steps: 1, matrix mixing; 2, ridged field forming; 3, seedling cultivation; 4, seedling cultivation management; 5, transplanting and topdressing. Organic phosphate fertilizer is added into a matrix, so that needed phosphorus is supplemented for the growing period of seedlings of the corn; the application amount of phosphatic fertilizer can be appropriately decreased in later-stage topdressing, so that the risk of environment pollution is effectively reduced. Due to the corn and cucumber intercropping planting method, the utilization rate of soil is increased; due to the proper plant spacing and row spacing, high economic value of the purple corn is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a planting method of environment-friendly purple corn. Background technique [0002] Purple corn is extremely high in phenolic compounds and anthocyanins. It is a unique corn variety in Peru. The cobs and kernels are purple. It is gaining more and more attention due to its health and nutritional properties. [0003] It contains 18 kinds of amino acids as tested by China Agricultural Grain Quality Supervision and Testing Center, and contains 21 kinds of trace elements, multivitamins and natural pigments necessary for the human body. It is especially rich in anti-cancer element selenium, intelligence-enhancing element zinc, iron and calcium, etc. Moreover, the taste is excellent, soft and tender, the skin is thin, slippery and slightly sticky, and has a special fragrance, so the food processed from purple corn is a kind of superior natural, delicious and...
