新干县园艺场现有柑桔面积650亩,其中结果树200亩。该场的柑桔产量,近年有较大的提高,1986年柑桔产量26.6万斤,1987年23.6万斤,特别是在1988年花期干热风灾害严重、各地普遍减产的情况下,其产量仍超历史,达33万斤。他们的主要经验是抓了以下六项切实可行的有效措施。一、扩穴改土近年来,园艺场把桔园扩穴改土、培肥土壤当作一项中心工作来抓。扩穴坚持高标准,埋肥坚持氮、磷、钾配合,有机肥和无机肥配合。每株埋肥量:6斤枯饼或6斤熟豆,1斤尿素,3斤磷肥,1.5斤石灰,40斤禾草或0.25方草皮。通过扩穴改土,提高了土壤肥力,改善了土壤结构,增强了土壤通透性和保水性,也增强了树体抗旱御寒能力。
Xinqian County horticultural field existing citrus area of 650 acres, of which 200 acres of trees result. The citrus harvest in this field has been greatly increased in recent years. In 1986, the output of citrus was 266,000 kg and that of 1987 was 236,000 kg. Especially in 1988 when the dry-hot wind blight was severe and the output was generally reduced everywhere, the output of citrus Ultra-history, up to 33 kg. Their main experience is to grasp the following six practical and effective measures. In recent years, horticultural field expansion of the orange hole in the garden, soil fertility as a central task to grasp. Expand the hole to adhere to high standards, buried fertilizer adhere to nitrogen, phosphorus and potassium with organic fertilizer and inorganic fertilizer. Buried fertilizer per plant: 6 pounds of dry cake or 6 pounds of cooked beans, 1 kg of urea, 3 pounds of phosphate fertilizer, 1.5 pounds of lime, 40 pounds of grass or 0.25 square turf. By expanding the hole to soil, improve soil fertility, improve the soil structure, enhance soil permeability and water retention, but also enhance the ability of trees to resist drought.
