Problems solved by technology

The storage period of bulbs in the Huanghuai area happens to be in hot and rainy summer. Due to high temperature and high humidity, a large number of bulbs often rot. In severe cases, the bulb rot rate can reach 60% to 70% or even higher, which seriously affects the amount of seed production. thereby affecting economic efficiency
[0004] Studies have shown that the occurrence of diseases during onion storage is affected by the environment and storage conditions, which will cause onion to rot. Rot, it is also proposed to dip quicklime in the incision when the onion bulbs are harvested, and change the pH value of the incision to reduce the rot rate, but the actual effect is limited, and a large number of onion bulbs still rot, which seriously affects the amount of onion seed production

Embodiment 1

[0028] A storage method for onion bulbs, the steps of the method are as follows:

[0029] a. The early-maturing onion variety is 'Yangchunhuang No. 3'. During the period of seedling cultivation, planting, and growth, do a good job in field management to reduce the occurrence of diseases and insect pests; Cut the green onion leaves at the bend of the false stem;

[0030] b. When the bulbs are harvested, pack 1 mesh bag per 100 green onion bulbs (20-25kg / bag), put 10 bags in one pile (Pile A), store them in a ventilated, cool and rain-proof place for normal temperature storage, and spray them with a mist machine 75% chlorothalonil powder 20g, 72% agricultural streptomycin 0.3g, spray once every 15 days;

[0031] c. On July 9, the cold storage was cleaned and disinfected. On July 10, the rotten bulbs were picked out and counted, and then the intact bulbs were bagged and put into storage. They were stacked 30cm above the ground, and the distance between adjacent piles was 50cm; t...

Embodiment 2

[0036] A storage method for onion bulbs, the steps of the method are as follows:

[0037] a. The mid-to-late maturing onion variety is 'Ziyu 88'. During seedling cultivation, planting, and growth, do a good job in field management to reduce the occurrence of diseases and insect pests; Cut the green onion leaves at the bend of the false stem;

[0038] b. When the bulbs are harvested, pack 1 mesh bag per 100 green onion bulbs (25-30kg / bag), put 10 bags in one pile (Pile A), store them in a ventilated, cool and rain-proof place for normal temperature storage, and spray them with a mist machine 75% chlorothalonil powder 25g, 72% agricultural streptomycin 0.4g, spray once every 15 days;

[0039] c. On July 9, the cold storage was cleaned and disinfected. On July 10, the rotten bulbs were picked out and counted, and then the intact bulbs were bagged and put into storage. They were stacked 30cm above the ground, and the distance between adjacent piles was 50cm; the temperature of th...

Abstract

The invention discloses an onion seedball storing method. The method includes the following steps that a, seedballs with stems are aired for 1-2 days in a field after being pulled up, the stems instead of the seedballs are aired, and onion leaves at the cauloid lodging and bending positions are shorn off; b, after being harvested, the seedballs are stored at normal temperature, 80-100 g of 75% chlorothalonil powder and 1-2 g of 72% agricultural streptomycin are sprayed to 1000 kg of seedballs through a mist sprayer once at the interval of 10-15 days; c, rotted seedballs are rejected, the complete seedballs are bagged and warehoused, the temperature of a refrigeration house is reduced to 25 DEG C to 15 DEG C to (11-12) DEG C from room temperature at the interval of 2-3 days, and finally the temperature in the refrigeration house is kept at 11-12 DEG C; d, after being warehoused, the seedballs are fumigated with 45% chlorothalonil fumicant, the usage amount is 200-250 mg / m<3>, and fumigation is carried out once at the interval of 10-15 days in the storage period; the humidity in the refrigeration house is controlled at 60-70%. The rotting rate of onion seedballs can be effectively reduced, and the onions are prevented from budding in the later storage period.

Description

technical field [0001] The invention relates to a method for storing onion bulbs. Background technique [0002] Onion (Allium cepa L., chromosome number 2n=2x=16) is a biennial vegetable of the genus Allium in the Liliaceae family (Liliaceae). It is extremely nutritious and has the effects of lowering blood pressure, lowering blood fat, relaxing blood vessels, anti-aging, anti-cancer, and anti-cancer. It is an ideal health-care vegetable. In addition to eating fresh, onions can also be processed into onion powder, onion sauce, onion oil, dehydrated onions and onion juice, etc., which are widely planted all over the world, and its annual production volume and production area rank third in the world's vegetable production. Although the history is only more than a hundred years old, it has developed rapidly and has become the largest country in the world in terms of planting area and output of onions, and it is an important vegetable for export and earning foreign exchange. ...
