夺取水稻、小麦等农作物丰收,需要靠水利,发展庭院经济也要靠水利。现将黑龙江省牡丹江市两个应用水利技术发展庭院经济的实例介绍给读者。一、大棚膜下微孔喷灌牡丹江市郊区水利局为了突破大棚灌水旧模式,1984年以来在区科委的配合下,引进外地经验,在多点进行了大棚膜下微孔喷灌新技术试验,获市科技成果推广三等奖。其优越性是: 1、这种喷灌方法变横向小垄为纵向大垄,采用地膜覆盖栽培,能提高地温2℃—3℃,克服了早期大棚内地温低的不利条件,可提前结瓜上市,增加经济效益。 2、用这种方法灌水既无深层渗漏,又无地面蒸发和输水损失,
To seize the harvest of rice, wheat and other crops, the need to rely on water conservancy, the development of the courtyard economy also rely on water conservancy. Presently, we present two examples of the economic development of the garden using water conservancy technology in Mudanjiang City, Heilongjiang Province to the readers. First, the greenhouse microporous sprinkler irrigation Mudanjiang Suburb Water Bureau in order to break the old pattern of greenhouse irrigation, since 1984 with the Science and Technology Commission, the introduction of field experience in a multi-point under the greenhouse film under the new technology of micro-irrigation sprinkler test, The city won the third prize of scientific and technological achievements promotion. Its advantages are: 1, this method of turning irrigation into a horizontal small ridge for the longitudinal ridge, the use of plastic film mulching cultivation, can increase the ground temperature 2 ℃ -3 ℃, to overcome the adverse conditions of the early greenhouse temperature is low, , Increase economic efficiency. 2, irrigation in this way neither deep leakage, no ground evaporation and water loss,
