specific Embodiment approach 1

[0012] Specific implementation mode one: the short petal nasturtium greenhouse direct seeding planting method of this embodiment mode is implemented according to the following steps:

[0013] 1. Land consolidation: Select (loose and fertile) black soil or chernozem land, in the greenhouse, spread farmyard manure on the surface before plowing, apply 200-500kg of farmyard manure per mu, then shallowly plow the soil and water once Water permeable, raking and leveling the land, drawing rows according to the width of 60-100cm, constructing planting plots, with a row spacing of 10-15cm, and completing land consolidation;

[0014] Two, sowing: a, first do germination treatment to the short-petal trombus seeds, about to be put into the GA that the quality concentration that configures is 1% after the plump and mature short-petal troutus seeds after water selection 3 Soak in the solution for 4 to 6 hours, take it out, rinse it repeatedly with water to wash away the residual liquid, and...

specific Embodiment approach 2

[0022] Embodiment 2: This embodiment is different from Embodiment 1 in that the farmyard manure described in step 1 is manure or compost.

specific Embodiment approach 3

[0023] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the depth of shallow turning in step 1 is 15-25 cm.

Abstract

The invention discloses a greenhouse direct seeding planting method of trollius ledebouri reichb in cold regions, and belongs to the technical field of plant cultivation. The method aims to solve theproblems that trollius ledebouri reichb is long in planting period and low in yield. The direct seeding planting method comprises the steps that 1, farmyard manure is spread on the earth surface before plowing in a greenhouse, then shallow turning is carried out on soil, and seeding cells are built; 2, direct seeding is carried out after seed germination accelerating and disinfection, and seeds are evenly covered with overlying soil after seeding, wherein the overlying soil is prepared from black soil, peat soil and fine sand; 3, after pentagonal basal leaves grow, a seedling strengthening agent is sprayed, when the average plant height reaches 5-7 cm, a nitrogen fertilizer is applied for the first time, and in the seedling period, the nitrogen fertilizer is applied every 15-20 days untilblooming; 4, harvesting is carried out. A seed direct seeding method is used, so that transplanting is not needed, and time and labor are saved; the reasonable proportion of the overlying soil fully considers texture and tilth features of the soil, water and fertilizer supply is guaranteed, and the seed germination rate is improved; due to greenhouse planting, the planting period is greatly shortened, and the operability is high.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a direct seeding planting method of nasturtium short petals in a cold area in a greenhouse. Background technique [0002] Trollius ledebouri Reichb is a perennial herb of the family Ranunculaceae, which grows in wet grasslands, forest meadows or riverside meadows at an altitude of 110-900m. It is distributed in Heilongjiang and northeast Inner Mongolia in my country. It is also distributed in eastern Siberia and the Far East of Russia (Zhang Dongqing et al., Research Progress of Short Petal Nasturtium, Chinese Patent Medicine, 2016, 38(11): 2448-2453.). Its flowers are bright in color and beautiful in shape. The flowers are used as medicine, which has the effects of clearing away heat and detoxification, reducing swelling and improving eyesight. It can treat chronic tonsillitis, pharyngitis, acute lymphangitis and other symptoms, so it has important ornamenta...
