秋菠菜越冬管理技巧

1、澆好封凍水。澆(jiao)封(feng)(feng)凍(dong)(dong)(dong)水(shui)(shui)(shui)必須做到(dao)“一(yi)定(ding)、二(er)適(shi)(shi)”。“一(yi)定(ding)”就是(shi)根(gen)據(ju)土(tu)(tu)壤(rang)(rang)(rang)含(han)水(shui)(shui)(shui)量多(duo)少決定(ding)澆(jiao)不澆(jiao)封(feng)(feng)凍(dong)(dong)(dong)水(shui)(shui)(shui)：絕對含(han)水(shui)(shui)(shui)量砂壤(rang)(rang)(rang)土(tu)(tu)在低(di)(di)于(yu)15％，壤(rang)(rang)(rang)土(tu)(tu)低(di)(di)于(yu)17％，黏土(tu)(tu)低(di)(di)于(yu)20％時應澆(jiao)封(feng)(feng)凍(dong)(dong)(dong)水(shui)(shui)(shui)。“二(er)適(shi)(shi)”就是(shi)適(shi)(shi)時和(he)適(shi)(shi)量澆(jiao)水(shui)(shui)(shui)：適(shi)(shi)宜澆(jiao)封(feng)(feng)凍(dong)(dong)(dong)水(shui)(shui)(shui)的(de)時間是(shi)白天(tian)土(tu)(tu)壤(rang)(rang)(rang)耕層能化凍(dong)(dong)(dong)，夜間有上凍(dong)(dong)(dong)的(de)時候(hou)；適(shi)(shi)量澆(jiao)水(shui)(shui)(shui)就是(shi)指封(feng)(feng)凍(dong)(dong)(dong)水(shui)(shui)(shui)量不能過大或過小，一(yi)般以接上底墑為(wei)宜。

2、追好越冬肥。迫施越冬(dong)肥(fei)能增加(jia)土壤養分含量(liang)，起到冬(dong)肥(fei)春用，促(cu)弱(ruo)轉壯作用。尤其對(dui)底肥(fei)少、地力差(cha)、苗情弱(ruo)的菜地更為重(zhong)要。一般畝施尿素10公斤或硫酸銨20公斤，結合澆封凍(dong)水追施越冬(dong)肥(fei)效果較好。

3、覆蓋防寒物。北方地區嚴寒期絕(jue)對(dui)低(di)溫對(dui)菜苗安(an)全越冬非常不利，因此(ci)應覆(fu)蓋(gai)防(fang)寒物，確保幼苗安(an)全越冬。覆(fu)蓋(gai)一般可在耕(geng)層土(tu)壤全部結(jie)凍后進行。用富含(han)有機質并經打碎搗細的(de)農家肥料覆(fu)蓋(gai)效果(guo)好，畝撒1000公斤(jin)左右。
