春播花生收获后留作来年春播,有发芽率低、成苗率低、产量低三大缺点。近几年来我县推广秋花生做种,种籽来源大部份由广东省调进。从广东省调运种子有下面两个问题:一是运储量大、运费高。如1985年调运27万斤,仅运费一项就花了2.7万元。二是种子供需不对路,不易调到。如我县需要“白沙选七”,这个品种在广东省收储较少。 经过几年试验,我所选用“白沙选七”种两季,早花生用地膜覆盖栽培,用收获的早花生再返秋播种,返秋收获的种子即为秋种,来年播种可以获得好收成,解决了向外省调种的问题。 早花生发芽起点温度为12℃,全生育期需要积温2800℃左右,全生育期115～125天,两季花生需要
Spring sowing perennial spring harvest for the coming year, there are low germination rate, low seedling rate, low yield three major drawbacks. In recent years, my county promote autumn peanut species, the majority of seed sources transferred from Guangdong Province. Seeding seeds from Guangdong Province has the following two problems: First, large transport capacity, high shipping costs. Such as transporting 270,000 pounds in 1985, only one shipping costs spent 27,000 yuan. Second, the seeds of supply and demand is not the right path, not easy to transfer. Such as my county need “Baisha selected seven”, this species in Guangdong Province received less storage. After several years of testing, I chose “Baisha selected seven” species of two seasons, early peanut mulching cultivation, with harvested early peanut before returning to the autumn seeding, autumn harvest is autumn seeds, the next year can be good seed sowing crops , To solve the problem of transferring seeds to other provinces. Early peanut germination starting temperature of 12 ℃, the whole growth period need to accumulate temperature around 2800 ℃, the whole growth period of 115 to 125 days, peanuts need two seasons
