新型一膜四行机采棉种植模式对棉花生长发育和产量的影响

The Impact of a New Type of One Film Four Row Machine Cotton Harvesting Planting Mode on Cotton Growth, Development, and Yield

摘要: 为了新疆机采棉高产高效提供新的种植模式，本研究针对新型一膜四行机采棉种植模式开展相关试验研究，开展不同模式对棉花出苗率、生育进程、农艺性状和产量构成的影响研究。结果表明：棉花新型一膜四行和一膜三行的出苗率均高于一膜六行(CK)，一膜六行(CK)前期生长较快，中后期生长较慢，生育期最长，新型一膜四行居中，一膜三行则相反。三种模式中的棉花株高、单株铃数表现为一膜六行(CK)最低，新型一膜四行居中，一膜三行最高；叶龄、单株果枝台数和果枝始节高的差异不大；新型一膜四行的蕾铃数最多。一膜三行和新型一膜四行的单铃重明显高于一膜六行(CK)，一膜三行和新型一膜四行的单铃重分别较一膜六行(CK)高7.54%和11.32%，一膜三行和新型一膜四行的单株铃数分别较一膜六行(CK)高24.37%和13.26%，一膜三行和新型一膜四行的收获铃数分别较一膜六行(CK)低10.01%和4.33%，新型一膜四行的单产籽棉较一膜六行(CK)高6.39%，一膜三行较一膜六行(CK)低3.32%。新型一膜四行有潜力作为新疆机采棉高产高效的新型种植模式。

Abstract: In order to provide a new planting mode for high yield and efficiency of Xinjiang machineharvested cotton, this study conducted relevant experimental research on the new one film four row machine harvested cotton planting mode, and studied the effects of different modes on cotton emergence rate, growth process, agronomic traits, and yield composition. The results showed that the emergence rate of the new type of cotton with one film and four rows and one film and three rows was higher than that of one film and six rows (CK). One film and six rows (CK) grew faster in the early stage, slower in the middle and later stages, and had the longest growth period. The new type of one film and four rows was in the middle, while one film and three rows were the opposite. Among the three modes, the cotton plant height and number of bolls per plant showed the lowest in one film six rows (CK), with the new one film four rows in the middle, and the highest in one film three rows; There is not much difference in leaf age, number of fruit branches per plant, and height of the beginning node of fruit branches; The new type of one film with four rows has the highest number of lace bells. The single boll weight of one film three rows and the new one film four rows is significantly higher than that of one film six rows (CK). The single boll weight of one film three rows and the new one film four rows is 7.54% and 11.32% higher than that of one film six rows (CK), respectively. The single plant boll number of one film three rows and the new one film four rows is 24.37% and 13.26% higher than that of one film six rows (CK), respectively. The single plant boll number of one film three rows and the new one film four rows is 10.01% and 4.33% lower than that of one film six rows (CK), respectively. The number of harvested bolls in one film with three rows and the new one film with four rows was 10.01% and 4.33% lower than that in one film with six rows (CK), respectively, The single yield of seed cotton in the new one film four rows is 6.39% higher than that of one film six rows (CK), one membrane with three rows is 3.32% lower than one membrane with six rows (CK). The new type of one film and four rows has the potential to be a high-yield and efficient planting mode for Xinjiang machine harvested cotton.
