Problems solved by technology

The green onion greenhouse seedling cultivation technology is relatively mature in Japan and other countries, and industrialized seedling cultivation and mechanized production have been carried out. However, the green onion varieties grown in Japan and other countries have shorter whites than Zhangqiu green onions, which are different from Zhangqiu green onions to produce high-quality products with light whites above 60cm With the fine planting mode mainly of scallions, the seedling raising technology of Japan and other countries cannot be directly used by grafting in the main production area of ​​Zhangqiu scallions
In China, the Institute of Vegetables, Shandong Academy of Agricultural Sciences has done experiments on the cultivation of green onion seedlings in plug trays. The height of the seedlings bred is about 30 cm, and the diameter of the green onion seedlings is slender, which is 50-70 cm tall compared with the seedlings bred by conventional field seedling raising techniques. I...

Embodiment 1

[0031] (1) Fertilize the soil. Green onion seedlings should choose loamy soil with fertile land, deep plowing layer, good drainage, water and fertilizer retention, neutral soil pH (suitable soil pH 5.9-7.4), and plots where onion and garlic vegetables have not been planted within three years. After harvesting the previous crops, remove the dead branches and leaves in time, apply enough base fertilizer, apply more than 5,000 kg of high-quality farm fertilizer per 667 square meters, or more than 5 square meters of decomposed chicken manure and cow manure, and apply 50 kg of ternary compound fertilizer per mu. Then deep plow the ground, and the ground preparation requires uniformity, fineness, looseness, and equality. Green onions are generally raised in flat borders, with a width of 1.5m-1.7m (including the border), and a length of 10-15m. Too wide and too long is not conducive to agricultural management such as fertilizer and water at the seedling stage, and too narrow and too ...

[0036] Embodiment 2: Seed band seedling raising technology and hole tray seedling raising technology comparison

[0037]Adopt seed belts with a seed spacing of 2 cm, sow single seeds, soak the seeds in the germination agent prepared from abamectin dregs before sowing, and set the row spacing of 8 cm, 10 cm, and 15 cm for three treatments; plug seedlings use 105 There are two specifications of mesh and 128 mesh, and 2 or 3 seeds per hole are used for sowing.

[0038] The seeds were sown on March 10, 2015, cultivated and managed in protected areas in winter-warm greenhouses, and the seedlings were measured on June 10. see table 1

[0043] Embodiment 3: comparison of seed belt seedling raising technology and field sowing seedling raising technology

[0044] Seed belt seedling cultivation adopts seed spacing of 2 cm, single seed sowing, soaking seeds in germination agent prepared from abamectin dregs before sowing, and setting row spacing of 8 cm, 10 cm, and 15 cm for three treatments; seedling seedlings are sown by hand The method of raising seedlings from the furrow.

[0045] Sowed on March 10, 2015, using winter-warm greenhouses for cultivation and management. The width of the border is 1.5 meters, the border is 30 centimeters, and the amount of seed per mu is about 2 kilograms. After planting in the field, take 0.9m for each treatment on October 10 2 Measure the output of the plot, and then convert the yield per mu. See Table 2 below.

Abstract

The present invention relates to the technical field of Allium fistulosum cultivation, in particular to a method of raising Allium fistulosum seedlings by using a seed belt, including: after land preparation and fertilizer application, sowing seeds by means of manual ditching with a seed belt seeder, wherein seeding depth of the seed belt is 3-4 cm, seed spacing is 2 cm, row spacing is 8-15 cm, and seeding is carried out with single grains; after seeding, earthing, leveling, flattening, and irrigating with sufficient seeding water; performing management in a seedling stage. The seed belt seedling-raising technology overcomes the defects in large field broadcasting cultivation and seedling tray cultivation and is a seedling raising method that is low in input cost, high in seedling emergence rate, capable of implementing uniform and robust seedlings, free of manual seedling selection in later stage and low in cost; by using the seed belt seedling-raising technology, seedling and stalk length is greater than that of seedlings raised with seedling trays and broadcasting, and plant height is also better.

Description

technical field [0001] The invention relates to the technical field of scallion cultivation, in particular to a method for growing scallion seedlings using seed tapes. Background technique [0002] The high-white scallions represented by Zhangqiu scallions have a large-scale planting area of ​​more than 740,000 mu in Shandong Province, accounting for more than 80% of the province’s scallion cultivation area. It is planted in some areas of Jiangsu Province, Inner Mongolia, Qinghai Province and other places. Zhangqiu scallion, a unique variety, has a planting area of ​​more than 150,000 mu in Zhangqiu City and surrounding areas, and occupies a leading position in the scallion industry in Jinan City and even our province. Zhangqiu scallion seedlings generally adopt the mode of sowing seedlings in the field in autumn and transplanting in the next summer. Traditional scallion seedlings are mainly raised by direct seeding in the field. In some areas, protected cultivation techni...
