Fresh-keeping Waxy Maize Double-season Cultivation Techniques along the Yangtze River
Rugao is located in the area along the Yangtze River in our province and is suitable for the growth of waxy corn. The implementation of double-season waxy maize cultivation techniques in the local area can meet market demand to a greater extent and significantly increase planting efficiency.
Variety selection of Jincheng Huayu, Su Yuxi No. 2, and other early-maturing, strong resistance, high quality varieties. After the seed drying, the seed dressing is used to control underground pests and seedling diseases such as earthworms, earthworms and earthworms.
Selecting sites for soil preparation should prevent isolation from common maize varieties. Space segregation (more than 100 meters away), time segregation (more than 15 days apart) and barrier segregation (forests, residential strips, etc.) can be used. Waxy corn is generally less resistant than ordinary corn, coupled with the characteristics of rainy spring and high-temperature and drought-prone conditions along the Yangtze River in the Yangtze River area. It is necessary to level the sorghum surface to ensure smooth drainage and drainage.
Season 1 seedlings are planted in the first quarter from March 15th to April 5th. Planting before the end of March needs to cover the mulch to increase the ground temperature, and to enter the planting in April. Both cover film cultivation and open field cultivation can be used. The second season is planted on July 15-30. In the first season, corn can be broadcasted directly or by transplanting seedlings, and transplanting seedlings can save production costs. The temperature during the second season of corn sowing is relatively high, and it is easy to produce frozen seedlings. It is advisable to broadcast the seeds in the second season with no tillage and sowing.
Reasonable density planting density should be based on season and species. Usually spring sowing has a longer growth period, a larger amount of growth, the density should be smaller; summer growth period is shorter, the growth is smaller, the density should be larger. Take Jinhua calyx as an example, spring sowing 4200 ~ 4500 strains per mu, summer sowing 4400 ~ 4600 strains.
Fertilizer and water management Fresh glutinous corn is harvested from the young fruit ear, and the principle of fertilization is to focus on the early application of early-onset hair growth. The basal fertilizer, jointing fertilizer, and panicle-fertilizer in spring sowing are accounted for 40%, 30%, and 30%, respectively. Other growing seasons should be supplemented with fertilizer and balance fertilizer as appropriate. Summer corn grows fast and has a short growing period. Basic fertilizer must be re-used, accounting for 50% of the total amount of fertilizer, and joint-fertilizer and panicle-fertilizer each account for 25%. Basal fertilizer is best combined with organic fertilizer and ternary compound fertilizer. The growth season of corn in the first season is vulnerable to the effects of spring rain and rainy rain. It is necessary to strengthen the management of field ditch systems, ensure the “three ditch†facilities and communicate with the outside world. The second quarter of the corn growing season is in the high temperature season, prone to drought, timely irrigation according to soil moisture, but also pay attention to the summer typhoon and heavy rain invasion, timely prevention of wind and drainage work.
Prevention and treatment of pests Diseases that currently have a major impact on corn include rough dwarfing disease, large spot disease, and small spot disease. Pests include aphids, corn borers, and giant salamanders. Although SBPH is not harmful to corn, it will spread rough dwarf disease and it is also the focus of prevention and control. In the first quarter of the year, corn is mainly controlled from late May to early June.
