姜保护地高产栽培分为大拱棚栽培、小拱棚栽培、地膜覆盖栽培,生育期分别比露地栽培延长60天、30天和15天。1999～2001年,五莲县石场乡共推广该技术407 hm~2,2000年经日照市科委组织专家抽地块测产,三种栽培模式的生姜产量每666.7 m~2分别为5 128.5 k g、4 221.6 kg、3 349.5 kg,比露地栽培产量2 546 kg,分别增产2,582.5 k、1 675.6 kg和803.5 kg,每666.7 m~2增加收入4 132.00元、2 680.96元和1 285.60元。该技术获日照市2000年科技进步一等奖。其主要栽培技术如下: 一、整地施肥土壤解冻后,细耙2～3遍,结合耕地,每
Ginger protected high-yield cultivation is divided into large arch shed cultivation, small shed cultivation, plastic film mulching, growth period than the open field cultivation extended 60 days, 30 days and 15 days. From 1999 to 2001, Shichang Township in Wulian County promoted the technology for 407 hm ~ 2. In 2000, experts from Rizhao City Science and Technology Commission organized land mass production testing. The yield of ginger for each of the three cultivation modes was 666.7 m ~ 2 128.5 kg, 4 221.6 kg and 3 349.5 kg, respectively. Compared with the open field cultivation, the yield was 2,546.5 kg, 1,675.6 kg and 803.5 kg respectively, and the income increased by 4 132.00 yuan, 2 680.96 yuan and 1 285.60 yuan per 666.7 m 2. The technology was Rizhao City in 2000 the first prize of scientific and technological progress. The main cultivation techniques are as follows: First, soil preparation and fertilization After soil thawing, fine rake 2 to 3 times, with arable land, each
