Potting method capable of achieving zinc deficiency of Solanum tuberosum L.

Abstract

The invention discloses a potting method capable of achieving zinc deficiency of Solanum tuberosum L.. The potting method comprises the following steps: performing block cutting, mixing blocks with chemicals, taking a flowerpot with a bottom hole and a laid gas permeable partition, matching quartz sand with a specification of 1-2 mm with quartz sand with a specification of 0.4-0.7 mm at a ratio of(2-5):1, performing even mixing and packaging into the flowerpot, planting the blocks in the flowerpot, covering the planted blocks with sand of 1.5-2.5 cm thick, performing pouring with ionized water, performing regular watering with ionized water, and when two compound leaves of each plant emerge and are fully unfolded, removing the quartz sand at roots, removing the mother blocks, and performing smoothing; and deficiency culture includes the steps: performing pouring by adopting a non-zinc Hogland liquid culture solution, performing regular watering with ionized water, and performing recording of the growth until harvest. According to the potting method, Solanum tuberosum L. exhibits significant deficiency symptoms through reduction of sources of elements in the culture cycle.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a pot cultivation method for zinc-deficient potatoes. Background technique [0002] Potato (scientific name: Solanum tuberosum L.), belonging to the Solanaceae herb, is the fourth most important food crop in the world after rice, corn, and wheat, and is closely related to people's lives. [0003] Trace elements play an important role in the growth and development of potatoes, and the function and deficiency symptoms of trace elements have always been the focus of scientific research. Many crops that rely on seeds to reproduce are prone to deficiency symptoms, because the seeds are small in size and low in trace element content, and are prone to deficiency symptoms. However, potatoes are usually not easy to obtain seeds, and the seed germination rate is not high. At present, it is mainly propagated in the form of tubers, and the content of trace elements in tubers is relatively high....

AI Technical Summary

Problems solved by technology

It was found that most of the tissue-cultured seedlings died after transplanting, and the effect was not good; the survival rate of transplanted seedlings using young shoots as materials was high, and symptoms of nutrient deficiency could be observed, but the culture containers were glass bottles, and potato tubers needed dark environment and space, so this cultivation method can only be limited to the seedling stage, and it is impossible to carry out research on the effect of nutrient deficiency on the whole growth period of potatoes, especially on the yield, so it has certain limitations
