Abstract


This paper aims at selecting fruit corn YuTian388for material in Nanning area,and carrying out research from planting, breeding technique, sowing time, density, different fertilizing period ratio and harvest period and other aspects, to investigate a set of high yield and good quality cultivation techniques of fruit corn, and providing theoretical basis for industrial structure adjustment and upgrade of Guangxi fruit corn. The results are as follows:1、The test results of planting pattern showed that:Single or double row planting has little effect on the output; The seedling transplanting technology has obvious effect on increasing output, compared with direct seeding increasing the output about10%; The increasing output effect of single seedlings planting and double seedlings planting is better then three seedlings planting.2、The test results of growing seedlings pattern showed that:the best effect is choosing100cavity and the128cavity of the seedling disk, sowing depth should be cover soil1/3, emergence rate than sowing depth0/3increased45%, sowing too deep or too shallow is not good for the seed germination and seedling quality. When choosing100holes floppy disk grow seedlings, the best transplanting time is3.41leaf age; When choosing128holes floppy disk grow seedlings, the best transplanting time is2.3leaf age.3、The analysis results of sowing period output show that:The highest yield were the sowing period of spring of March and April and the Autumn of August, among them the highest yield was March sowing period, spring increase production is better than autumn sowing; Although there are harvest in the two seeding period of Mid June to early July and late September to early October, the yield is not high; Sowing in the mid and late October to January of the following year, generally there are not yield, this period is not suitable sowing4、The test results of density showed that:When every Mu Density is less than2500plants, the output of unit area of the fresh fruit ear number is small, the total output is too low; When every Mu Density is large than4000plants, though the output of the fresh ear is large, that quality of fruit ear was very poor, commodity rate is not high, and the yield is low. To obtain high yield and high quality, the most suitable planting density is3000plant/mu.5、Different fertilizing period ratio experiment showed that:To a certain proportion of fertilizer dosage can ensure the quality and yield of fruit corn. During the whole growth period total using quantity fertilizer ratio, basal fertilization accounted for40%-60%,seedling fertilization accounted for30%-50%, panicle-spikelet fertilizer fertilization accounted for10%-20%, can be obtained high yield and good quality.6、The test results of harvest in Spring and autumn showed that:The best quality of fruit corn is20-24days after pollination, soluble sugar content above21%,100-grain fresh weight is28g, grain moisture content is70%, and the best tasting edible quality is the most suitable harvest period. Influence by the weather condition of harvesting, autumn fresh fruit ear is more stable than spring, the goods shelves time is longer than the spring harvest
