Abstract
The invention relates to a special water-retention fertilizer for seed corn, which is formed by mixing a furfural residue, CO(NH2)2, (NH4)2HPO4, ZnSO4*7H2O and a water-retention agent at an air-dry weight ratio of (89.07-94.38):(3.46-5.75):(1.90-4.47):(0.16-0.38):(0.10-0.33). The fertilizer integrates a long-acting function of the furfural residue, a water-retention function of the water-retention agent, and nutritive functions of CO(NH2)2, (NH4)2HPO4 and ZnSO4*7H2O, and solves the problems that the seed corn cannot be pollinated normally, the setting percentage is reduced, and a yield of the seed corn is reduced due to the fact that the natural water content of soil of a corn seeding field in Hexi Corridor of Gansu Province is low, emergence of seedlings is out of order, the seedlings are deficient or dead, and a drought always appears in a flowering period.
Description
Technical field
The present invention relates to production of hybrid seeds Maize Production field, relate in particular to the special-purpose fertilizer of a kind of production of hybrid seeds corn water-retentivity.
Background technology
Landlocked irrigated area, the west of a river, Gansu water resources is abundant, and light application time is long, and day and night temperature is big, and is dry, and natural isolation condition is good, is the desirable place of the corn seed production of hybrid seeds and storage, over nearly 10 years, has set up production of hybrid seeds Maize Production base 100,000 hm
2, seed yield reaches 6.5 Yi ㎏.The subject matter that exists is at present: landlocked irrigated area, west of a river steam output is big, quantity of precipitation is little, water resources shortage, the soil natural water content was low when production of hybrid seeds corn was sowed mid-April, and it is irregular to emerge, and causes the disconnected ridge that is short of seedling, often run into arid in flowering period, production of hybrid seeds corn can not normally be pollinated, and setting percentage reduces, and causes production of hybrid seeds corn yield to descend.Therefore, research and development collection nutrition, water conservation are the key point that the special-purpose fertilizer of the production of hybrid seeds corn water-retentivity of one becomes composite fertilizer's research and development.In recent years, the research of relevant composite fertilizer has been subjected to extensive concern, but the special-purpose fertilizer of relevant production of hybrid seeds corn water-retentivity yet there are no report.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of to collect nutrition, water conservation be that the production of hybrid seeds corn water-retentivity of one is special-purpose fertile.
