Embodiment 1
[0038] Crossbreed flax and produce hybrid fruit as follows:
[0039] 1. Sowing
[0040] Before sowing, apply basal fertilizer in the field, the basal fertilizer is compound fertilizer, the consumption is 12 kg / mu, the effective content of the compound fertilizer is 45%, N:P:K=1:1:1. 40 groups of hybrid combinations were designed in advance, and the hybrid parents were planted adjacent to each other as far as possible, and the parents were separated by ridges. On October 9th, the seeds were sown in a drill without leaving a ditch, and the effective sowing density was 2000 grains / m 2 .
[0041] 2. Field management
[0042] Irrigation: Use micro-spray irrigation once after sowing. Weeding: 60 grams of 56% sodium dimethyltetrachloride + 50 milliliters of 5% quizalofop-ethyl are used for weeding in the fir-type period.
[0043] 3. Hybridization
[0044] Pre-treatment: On the 7th day before the emasculation of the female parent, all the flax were irrigated. Irrigation method: d...
Embodiment 2
[0050] Crossbreed flax and produce hybrid fruit as follows:
[0051] 1. Sowing
[0052] Base fertilizer application: before sowing, apply base fertilizer in the field, the base fertilizer is composed of crushed flax cake and compound fertilizer, the consumption of the flax cake is 30 kg / mu, and the consumption of the compound fertilizer is 6 kg / mu, the compound fertilizer The effective content is 45%, N:P:K=1:1:1.
[0053] Open acupoints: the depth of the acupoints is 4-7cm, the distance between the acupoints is 10cm, and the row spacing is 20cm.
[0054] Sowing: Plant the same hybrid combination as in Example 1, wherein the hybrid parents are planted adjacent to each other as much as possible, and the parents are separated by ridges. Sow on October 9th, 10 seeds / every hole, sow evenly in described hole, effective sowing density 500 grains / square meter, do not cover soil after sowing.
[0055] 2. Field management
[0056] Irrigation: Use micro-spray irrigation once after s...
Embodiment 3
[0063] Crossbreed flax and produce hybrid fruit as follows:
[0064] 1. Sowing
[0065] Before sowing, base fertilizer is applied in the field. The base fertilizer is composed of pulverized flax cake and compound fertilizer. The consumption of the flax cake is 20 kg / mu, and the consumption of the compound fertilizer is 8 kg / mu. The effective content of the compound fertilizer is is 45%, N:P:K=2:1:1.
[0066] Open acupoints: the depth of the acupoints is 4-7cm, the distance between the acupoints is 10cm, and the row spacing is 20cm.
[0067] Sowing: Plant the same hybrid combination as in Example 1, wherein the hybrid parents are planted adjacent to each other as much as possible, and the parents are separated by ridges. Sow on October 9th, 8 seeds / hole, evenly sow in the hole, effective sowing density 400 seeds / square meter, do not cover soil after sowing.
[0068] 2. Field management
[0069] Irrigation: Use micro-spray irrigation once after sowing. Weeding: 60 grams of ...
