Embodiment Construction

[0023] A method for raising seedlings of single-season paddy seedling machine-transplanted with high yield per mu, comprising the following steps:

[0024] (1) Preparation of seedling substrate: 250 pot seedling trays are selected for each hectare of field, the size is 28cm×58cm, each tray requires 5Kg seedling substrate, the substrate is a mixture of vermicompost, domestic peat and field soil, and the mass ratio is 2 :1:1;

[0025] (2) Selection of seedling fields: choose paddy fields that are convenient for seedling transportation, square in size, unimpeded in irrigation and drainage, and medium to high in fertility. The ratio of seedling fields to large fields is 1:80;

[0026] (3) Seedling board preparation: water the first plowing 15 days before sowing, second plowing and raking 3 days before sowing, apply ternary compound fertilizer 150Kg per hectare, and make standard seedling board specifications. The surface width is 1.3m, the ditch width is 0.25m, the ditch depth is...

Abstract

The invention discloses a seedling-raising method of single cropping blanket-type rice seedlings with high acre yield through mechanical transplanting, and the method has the advantages that the vegetative mass of a seedling transplanting plant is big, stress resistance is strong and turning green and rooting are rapid after mechanical transplanting; domestic peat, wormcast and yellow sand are used as seedling raising substrates, the nutrient content is improved, seedling growth is benefited, nutrition is balanced in a seedling growth period, without fertilizer deficiency, seedling burnt, andexcessive vegetative growth, chemical control management is easy, stress resistance of the transplanted rice seedling is good, lodging is uneasy, stalk is thick and strong, and yield is high; the seedling-raising method of blanket-type rice seedlings through mechanical transplanting provided by the invention is simple to operate, expands the application scope, reduces labor intensity and labor cost of the farmer, saves both time and labour, has acre yield up to 800kg, has good economical benefits and social benefits and is suitable for large scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for raising seedlings of single-crop rice blanket seedlings with high yield per mu. Background technique [0002] In recent years, with the transfer of rural labor forces and the transformation of agricultural production methods, my country's rice machine transplanting technology has developed rapidly and made great progress. In 2015, the level of machine-transplanted rice in Anhui Province exceeded 34%. However, the traditional machine-transplanted rice blanket seedling raising technology has problems such as poor seedling quality, slow greening and living, low ear formation rate, unreasonable population construction, premature aging and lodging in the later stage, and low and unstable yield. These problems need to be resolved urgently. Contents of the invention [0003] The purpose of the present invention is to make up for the defects of the prior a...
