Abstract
The invention relates to an agricultural implement, which is a swaddled early sowing corn seed. A protective layer is wrapped outside the corn seed which is characterized in that the protective layer consists of the following materials in part by weight: 40 to 60 parts of peat soil, 15 to 25 parts of humic acid, 10 to 15 parts of zeolite powder and 2 to 8 parts of water repellent. Since the protective layer is wrapped outside the corn seed, the permeation of water can be controlled after sowing so as to delay seed germination and be immune from late spring coldness. The seed is protected by the protective layer against frost damage even though the seed germinates before the late spring coldness. The seed has high cold resistance when the bud bursts out of the soil, so the seed can resist transient temperature drop. Manual adjustment and control of germination at a fixed time is realized by properly adjusting parameters of the protective layer. As a result, the corn seed can be sowed in advance to prolong the growth time of the crop and improve the yield and quality of the corn.
Description
Technical field
The present invention relates to a kind of processing method of corn seed, promptly a kind of packaging method of early sowing corn seed.
Background technology
Corn is the staple crops of northern China, also is the important food and the raw material of industry.Improve corn yield and quality,, promote development and national economy, all have important effect for the living standard that improves the people.Improve maize yield and quality, just must widely popularize good corn variety.At present, the kind of corn is a lot, and the yield and quality of different cultivars often has very big difference.In general, exist proportional relation between the vegetative period of maize yield and quality and corn.In other words, the output height that vegetative period is long, quality better, vegetative period, the yield and quality of weak point was often less better.Corn producing region with to the north of 42 ° of the north latitude is an example, and the corn per mu yield in 120 days vegetative period is about 750kg, and the corn per mu yield in 130 days vegetative period can reach 1000kg, and the corn per mu yield in 140 days vegetative period can reach more than the 1100kg.Particularly relatively good, the economic worth of some qualities is than higher corn, and vegetative period is all long., because the frost-free season in the north is shorter, vegetative period, long corn was difficult to maturation, so the peasant have to select relatively shorter kind plantation in some vegetative period.If plantation long kind in vegetative period will adopt a technology such as plastic mulching, cost is higher, but also can cause mulch film to pollute, and is difficult to large tracts of land and promotes.Discover, the farmland in above-mentioned area since the middle ten days and the last ten days in March temperature just raise, to early April, change soil layer and can reach 600-700mm.At this moment change is logical fully owing to freeze layer, and the moisture of changing soil layer can not run off downwards, can only move upward, and " the anti-slurry " phenomenon occurs, be the best stage of topsoil soil moisture content, and ground temperature is higher, can sow fully, and seed also can germinate.If during this time sow successfully, sufficient growth time should be provided for the corn variety that grow breeding time., a kind of " cold in the late spring " can occur the mid-April the fraction of the year of many, temperature descends suddenly when the time comes, and upper soll layer forms the frost layer of 10-30mm, reaches 2-4 day perdurabgility, and is very big to kind of bud harm, can cause the large tracts of land cur.So in order to hide cold in the late spring, people can only wait until after the cold in the late spring that April 20 could be sowed later.This has not only missed best soil moisture content, has lost valuable time, but also the tensity that can increase the weight of to sow in spring reduces seeding quality.
