5.1-2. 1. Production and method:
a) The germplasm bank and the single silicon drug yield prediction network are used to determine the total yield of the single 10 liquid plates, b, the graded area can measure the late milk yield once per foot, measure the dry gum content, record the number of rubber making force each month, and calculate the average annual yield of each plant. After 3 years of full measurement, select the best production for 3 years.
Graded area determination and record yield weight, measure the rubber yield of the first three changes (the first, middle and last ten days of measurement) and at the same time measure the number of rubber making knives per piece, use the intermittent application cycle to measure the yield after the stimulant is used from the first year to the year, and measure the dry gum content in the early year within the production plan: calculate the annual dry gum yield and unit area dry gum yield) The production system model area does not deduct the edge of the tree, record the latex yield of each tree, and then calculate the rubber content per unit area. ) The standard method or D[[-925 5.1.2.2 Calculation method:
NY/T 607—2002
People's Field Germplasm Bureau and separately set up two measurement methods for mothers: one average special latex yield (g/t/):: total average latex yield per plant (g)/number of cuttings. 6) Primary system yield calculation method:
Monthly special latex yield (kg) (monthly average latex yield per cutting (%) × monthly replacement of rubber knife/1n monthly average latex yield per cutting () = monthly average latex yield per plant (monthly Average rubber content (%): Monthly rubber yield per plant (g) = Monthly average rubber yield per group () × monthly measured rubber number (0CG) - Annual rubber yield per plant (R) - Sum of monthly rubber yields, Annual milk yield per plant (k) = Sum of monthly milk yields, Half-year average rubber yield per plant (k) = Annual rubber yield per plant (kg) / Annual milk yield per plant (kg) x 100, Half-year average rubber yield per plant (g//) = Annual rubber yield per plant (g) × Annual total rubber yield number × 1000. Calculation method of the production ratio of the commercial area:
Total latex production of the area (kg) = Average latex production per batch in the area in a month () × Number of batches per month: Average effective production per batch in the area in a month g = Average milk production per batch in the area in a month () Average monthly thousand batches (kx) = Average dry rubber production per batch in the area in a month [kg) × Number of batches per month and average dry rubber production (kg) = Total dry rubber production of the area in a month (kg) / Area measurement Yield per plant; Average annual dry rubber yield (kg)·Effect of dry rubber yield per plant in each period: Average annual dry rubber yield per hectare (/m1 = total monthly dry rubber yield of each plot)/actual area of the plot (hm\),
Annual average annual total rubber yield of the plot (kg)/total rubber yield of the plot (g) × 100. 1) Calculation method of production ratio plot yield: weigh the collected latex, take the rubber content of the combined latex to calculate the yield per unit area.
-monthly total rubber yield (R) = the sum of the monthly rubber yield per cavity (kg)/actual area (hm\).
-monthly total rubber yield (R) = the sum of the monthly rubber yield per cavity (kg)/actual area (hm\). 5.2 Latex quality test
