马龙县是发展果树的新区,人少地多,气候温凉,日照充足,昼夜温差大,适宜栽培苹果。与一些地区相比,所产苹果具有早熟、着色早、着色好、风味浓的特点。1974年红星苹果首批出口香港试销,得到市场好评。但过去栽的苹果树靠外地调入苗子,少部分自己培育,主要原因是砧木种子播种后不易出苗或出苗率低。为贯彻“自采、自育、自栽”的三自方针,满足发展苹果的苗木供应,育苗是急需解决的首要问题。根据调查了解,过去群众在育苗中,喜欢用山丁子,不愿意用海棠,其原因是山丁子种子小出苗容易,海棠种子大不易出苗。这主要在于播种前种子很少进行层积处理,仅
Malone County is the development of fruit trees in the new area, less land, cool climate, adequate sunshine, large temperature difference between day and night, suitable for cultivation of apples. Compared with some regions, the produced apple has the features of early maturity, early coloring, good coloring and strong flavor. Red Star Apple in 1974 the first batch of Hong Kong export test, praised by the market. However, in the past, apple trees planted in the field were transferred to the seedlings and cultivated by themselves for a small part. The main reason was that the seedlings of the rootstocks were not easy to germinate or had a low emergence rate after sowing. To carry out the “self-mining, self-cultivation, since the planted” three-self approach to meet the development of apple seedlings supply, nursery is the primary problem to be solved urgently. According to the survey, in the past, people in the nursery, like to use the mountain Dingzi, do not want to use Begonia, the reason is that the small seedlings of small, easy to germinate, Begonia seed is not easy to emerge. This is mainly due to the fact that the pre-seeding seeds are rarely stratified, only
