Embodiment 1

[0029] A kind of root-controlling seedling raising and transplanting method of corn of the present invention comprises the following steps:

[0030] (1) Appropriate altitude distribution range; cultivated land in Yuxi City is distributed at an altitude of 350-2650m, mainly concentrated in the range of 1300-2000m. This technology is suitable for application in places with water conservancy guarantees in Yuxi City;

[0031] (2) Seedbed land arrangement; Yuxi City has no effective precipitation from March to April, so the land where this technology is applied must have water conservancy protection. First material preparation, 100 kg of decomposed and sun-dried farmyard manure, 1 kg of three 15 compound fertilizers, and 8 square meters of plastic film; then select 4.8 square meters as a seedling field in a flat place for transplanting, and manually level it; Cover the leveled place with a film, and make a small hole every 30 cm in the film, so that the excess water on the seedbed ...

Embodiment 2

[0043] The difference between embodiment 2 and embodiment 1 is:

[0044] A kind of root-controlling seedling raising and transplanting method of corn of the present invention comprises the following steps:

[0045] In step (1), the suitable altitude distribution range; cultivated land in Yuxi City is distributed at an altitude of 350-2650m, mainly concentrated in the range of 1300-2000m. This technology is suitable for application in places with water conservancy guarantees in Yuxi City ;

[0046] In step (2), the arrangement of seedbed land; Yuxi City has no effective precipitation in March-April, so the application plots for this technology should have water conservancy guarantee. First material preparation, 150 kg of decomposed and sun-dried farmyard manure, 1 kg of three 15 compound fertilizers, and 7 square meters of plastic film; then select 4.5 square meters in the flat place of the transplanting plot as a seedling field, and manually level it; Cover the leveled place...

Embodiment 3

[0056] The difference between embodiment 3 and embodiment 1 is:

[0057] A kind of root-controlling seedling raising and transplanting method of corn of the present invention comprises the following steps:

[0058] In step (1), the suitable altitude distribution range; cultivated land in Yuxi City is distributed at an altitude of 350-2650m, mainly concentrated in the range of 1300-2000m. This technology is suitable for application in places with water conservancy guarantees in Yuxi City ;

[0059] In step (2), the arrangement of seedbed land; Yuxi City has no effective precipitation in March-April, so the application plots for this technology should have water conservancy guarantee. First of all, material preparation, 120 kg of decomposed and sun-dried farmyard manure, 1 kg of three 15 compound fertilizers, and 7.5 square meters of plastic film; Cover the leveled place with a film, and make a small hole every 28 cm in the film, so that the excess water on the seedbed can flo...

Abstract

The invention discloses a root control and seedling culture transplanting method for maize. The method comprises the following steps of (1) determining an appropriate altitude distribution range; (2)arranging a seedbed land; (3) treating maize seeds; (4) carrying out seedbed seed sowing; (5) carrying out seedbed land moisture management; (6) carrying out timely transplanting; (7) carrying out lifting of seedlings; (8) determining the field planting specification and density; (9) carrying out full-field plastic film mulching; (10) carrying out fertilizing at proper time; (11) preventing and controlling plant diseases and insect pests; and (12) carrying out harvesting timely, specifically, timely carrying out harvesting, threshing, drying and storing of the maize in the full ripening periodso as to realize grain warehousing. According to the method, after the maize seedlings are transplanted, the survival rate is high, a reasonable group structure can be guaranteed, high yield is achieved, through the comparative test of the maize, the yield per mu of root control and seedling culture transplanting is increased by 35.7% compared with that of contrast cultivation (spot seeding), thegrowth period is shortened by 7-10 days compared with that of contrast cultivation, and the contradiction of crops for rotation can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of reproduction, and in particular relates to a transplanting method for root-controlled seedling raising of corn. Background technique [0002] Yuxi City, a prefecture-level city in Yunnan Province, is the third largest city in Yunnan Province. The pre-Qin period belonged to the ancient Dian Kingdom. Yuxi is located in the central part of Yunnan Province, with geographical coordinates between 23°19′~24°53′ north latitude and 101°16′~103°09′ east longitude. It borders the provincial capital Kunming in the north, Pu'er in the southwest, Honghe Hani and Yi Autonomous Prefecture in the southeast, and Chuxiong and Yi Autonomous Prefecture in the northwest. The total area is 15285 square kilometers. Yuxi has a mild climate, with a temperature difference of 16°C throughout the year, mainly in spring and autumn. The annual average temperature is 17.4~23.8℃, and the average annual precipitation is 670~2412 mm. It...
