Seedling growing and filling method for potato

Abstract

Provided is a seedling growing and filling method for potatoes. The invention relates to a seedling growing and filling method for potatoes. An objective of the invention is to provide a seedling growing and filling method for potatoes. The seedling growing and filling method for potatoes comprises: 1, accelerating germination: placing cut sprout tubers in a mixed composite reagent, soaking for 15 min, taking the sprout tubers out, piling up the sprout tubers and wet sand in a layered manner (that is, placing a layer of sprout tubers on a layer of wet sand), keeping stacking temperature be about 18-20 DEG C, to make sprouts grow to 2-3 cm, and processing the sprouts under scattered light for 2-4 days; 2, bedding: putting the accelerated sprouts uniformly in a compound substrate at an interval of 1 cm, and then covering 10-12 cm wet compound substrate, and building an arched shed to cover; 3, cutting sprouts and transplanting: after sprouts come up out of ground, gently pushing aside the covered substrate, cutting a 5-6 cm sprout with roots, planting the sprout on the position which needs filling the gaps with seedlings, adding required amount of water; then covering the pushed aside compound substrate again, after about 7-8 days, performing next sprout cutting and seedling filling, and so forth.

Description

Technical field [0001] The invention relates to a method for growing and replenishing seedlings of potatoes. Background technique [0002] If the potato seed potatoes are not processed, the teeth are cut and seeded immediately after the cellar, then after sowing, not only will the emergence of seedlings appear uneven, incomplete, and not robust, but also late emergence, and sometimes the buds have to be buried in the soil 40 Seedlings emerge after many days, the reason is that the cellar temperature is relatively low, and the body temperature of the seed potatoes is also relatively low. Although they have been stored for several months and passed the dormant period, they are still in forced dormancy. Sow it into the ground in spring, the ground temperature rises slowly, the body temperature of the bud block rises slowly in the ground, and the small environment of each bud block is different. Therefore, germination is slow and seedling emergence is slow, and the emergence sequenc...

AI Technical Summary

Problems solved by technology

Therefore, germination is slow, seedling emergence is slow, there is a big difference in the emergence of seedlings, and even some buds will rot, resulting in lack of seedlings.

Thereby reducing the yield, in order to avoid these problems, it is necessary to carry out seedling treatment
