Fertilizing method for cotton planted in jujube and cotton intercropping mode

[0048] see figure 1 As shown, embodiment 1 provides a method for fertilizing cotton 102 in a jujube-cotton intercropping planting pattern. In view of ventilation and light transmission, the planting direction of jujube 101 should be north-south. Between planting cotton 102, implement according to the following process:

[0049] Apply oil residue 150kg / 666.7m between rows of jujube tree 101 2 , Urea 18kg / 666.7m 2 , diammonium 30kg / 666.7m 2 , Potassium sulfate 10kg / 666.7m 2 , zinc sulfate 1kg / 666.7m 2 , manganese sulfate 0.5kg / 666.7m 2 And boron fertilizer 1kg / 666.7m 2 , Mechanical deep plowing into the soil.

[0050] Between jujube trees 101, cotton 102 is planted in a wide and narrow row configuration mode, and covered with film. 102 cotton row spacing configuration patterns are [(20cm+40cm+20cm+40cm+20cm+40cm+20cm)+60cm]×12cm, namely the narrow row spacing a=20cm of cotton 102, the wide row spacing b=40cm of cotton 102, In all cotton 102 rows: the distance

[0053] see figure 2 Shown, embodiment 2 provides the fertilization method of cotton 102 in a kind of jujube-cotton intercropping planting pattern, and this method is to plant cotton 102 between the jujube tree 101 bands of 4-5 years old, implements by following process:

[0054] Conduct soil preparation and base fertilizer application on the land between jujube tree 101 zones: oil residue 170kg / 666.7m 2 , Urea 20kg / 666.7m 2 , Diammonium 32kg / 666.7m 2 , Potassium sulfate 11kg / 666.7m 2 , zinc sulfate 1.5kg / 666.7m 2 , manganese sulfate 0.7kg / 666.7m 2 And boron fertilizer 1.1kg / 666.7m 2 , Mechanical deep plowing into the soil.

[0055]Between jujube trees 101, cotton 102 is planted in a wide and narrow row configuration mode, and covered with film. The row spacing configuration mode of 102 cotton plants is [(25cm+40cm+25cm+40cm+25cm)+55cm]×11cm, that is, the narrow row spacing g=25cm of cotton 102, the wide row spacing h=40cm of cotton 102, and 102 rows of all c

[0058] see figure 2 Shown, embodiment 3 provides a kind of fertilization method of cotton 102 in jujube-cotton intercropping planting pattern, and this method is to plant cotton 102 between the jujube tree 101 bands of 4-5 years old, and this fertilization method is the same as the fertilization of embodiment 2 The method is roughly the same, except that the row spacing configuration mode of 102 cotton plants is [(30cm+45cm+30cm+45cm+30cm)+60cm]×11cm, that is, the narrow row spacing g=30cm of cotton 102, and the wide row spacing of cotton 102 Row spacing h=45cm, in all cotton 102 rows: the 1st row, the 6th row distance i=110cm from the nearest jujube tree 101, the 2nd row, the 5th row distance j=140cm from the nearest jujube tree 101, the 3rd row , The distance between the fourth row and the nearest jujube tree 101 is k=185cm. Near crown area refers to the area that is 110-140cm with the distance of jujube tree 101, i.e. the 1st row, the 2nd row, the 5th row and the 6th row nea
