Problems solved by technology

However, due to its long flowering and pod period and many spraying times, the spraying and harvesting workload is large, and the seed production cost is high; it also causes certain pollution to the base environment; because this method mainly uses chemical control means and Prolonging the harvest period to increase seed yield solves the impact of external biological factors on seed production to a certain extent, but does not use auxiliary techniques and measures such as chemical regulation to improve the orderliness of seed ripening at the anthesis and pod stage for the reproductive characteristics of the plant itself. degree, seed setting rate and grain weight, and further increase the level of seed yield per unit area

Embodiment 1

[0016] Comparative examples of different root nutrient sprays

[0017] The embodiment adopts single factor random block design, divides 4 kinds of different treatment levels A-clear water (for contrast), B-96% potassium dihydrogen phosphate (0.15%), C-amino acid micro-fertilizer (AA>100g / l) D- Trace boron foliar fertilizer (polysodium borate ≥ 99%), plant-to-plant spacing 10cm, row spacing 25cm; each plot length 3.5m, row width 1.5m, plot area 5.25m2, 3 repetitions, a total of 12 plots. Foliar spraying was carried out at the pod setting stage, and it was carried out in the evening without rain, and sprayed continuously for 3 days, and the fixed plants were covered with nylon mesh bags. At the maturity stage, samples were taken to test the species (economic traits) and their dry weight were measured, and the treatment effect was compared. The test results show that among all the treatments, spraying a small amount of polymerized boron (B) fertilizer has the best treatment effec...

Embodiment 2

[0025] The screening embodiment of paclobutrazol optimal concentration

[0026] The embodiment adopts a single-factor randomized block design, and designs 4 different drug concentration levels, CK-spray water, B1: 50 mg / L, B2: 100 mg / l, B3: 150 mg / l. The row spacing of the test plot is 25cm, the plant spacing is 10cm, 2-3 seeds per hole, 2 plants per hole, each treatment plot is 3.0m long, 1.5m wide, and the area of ​​the plot is 4.5㎡. Repeat 3 times, a total of 12 plots. Spray different concentrations of paclobutrazol at the early stage of flowering, set the plants with nylon mesh bags, and take samples at the mature stage to test the species (economic traits) and measure their dry weight. Compare the effects of different treatment concentrations. Test result shows, wherein paclobutrazol (15%) formula is best with the treatment effect of 50mg / l concentration, compares with CK, all has more significant comparative advantage (table 3-table 4) on indicators such as yield consti...

Embodiment 3

[0033] Topping and non-topping comparative examples

[0034] The embodiment adopts inter-ratio implementation design, taking no topping as contrast (CK). Different topping periods are test treatments of T1: 18 leaves, T: 20 leaves, T3: 22 leaves, and the row spacing in the test plot is 25cm, and the plant spacing is 10cm, 2-3 seeds per hole, 2 plants per hole, each treatment plot is 3.0m long, 1.5m wide, and the area of ​​the plot is 4.5㎡, repeated 3 times, a total of 12 plots, during the flowering and pod stage (knot topping treatment) ), set the plant in a nylon mesh bag, take a sample at the maturity stage to test the species (economic traits) and measure its dry matter weight. Comparing the treatment effects of different topping periods, the test results show that: the topping treatments have different degrees of promotion effects on the yield components and biomass of vines, but T2 treatment (20 leaves) has no effect on vines. Seed pulling rate, grain number per plant an...

Abstract

The present invention relates to the technical field of agricultural cultivation, in particular to a method for improving the seed setting rate and grain weight of the vine-shaped jackfruit. Interplanting management is carried out until the vine-shaped jackfruit enters the pod stage, and the steps are as follows: (1) spraying the pods at the initial stage Paclobutrazol, the concentration is 50-150mg / l, spray 3 times continuously on sunny days; (2) In the middle stage of flower pods, when the number of seeds in each fruit pod is 1-2, spray water-soluble fertilizer on the leaves; (3) Flower pods Topping in the later stage is used to increase the seed setting rate and grain weight of the vine-pulling seeds. The present invention combines the main problems of the vine-pulling flower pod stage and the ripening characteristics of the fruit pods, and combines the "pre-control, mid-supplement, and post-threshing" seed production mode, Comprehensively adopt the method of "external root nutrition" + "chemical regulation" + "agronomic measures" to overcome the influence of the unfavorable external environment and the inconsistency of seed maturity and saturation and the limitation of its own pod fruiting characteristics to improve vineness. The seed setting rate and grain weight can be improved, and the seed yield level can be further improved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for improving the seed-setting rate and grain weight of vine-grained jackfruit seeds. Background technique [0002] Seeds are the material basis for the production of Chinese herbal medicines. Improving seed setting rate and grain weight is one of the effective ways to increase seed yield, and it is also an important guarantee for the stable supply of high-quality provenance. At present, in its large-scale seed production, it mainly uses regular spraying of different pesticides in the pod stage to prevent and control the damage of different types of pests to reproductive organs; increase the number of harvests to increase its seed setting rate and seed yield. However, due to its long flowering and pod period and many spraying times, the spraying and harvesting workload is large, and the seed production cost is high; it also causes certain pollution to th...
