Embodiment

[0026] The present invention has carried out experiment and implementation in Jinhai Farm Experimental Base, Dafeng City, Jiangsu Province. The total salt content of the soil in the 0-20cm plow layer of the tidal flat saline-alkali land is 3.1‰±0.3‰wt, with 3 replicates, each of which is 43.2m 2 , the tested variety is okra Aili Wujiao. The sowing date was May 10, 2011, and the harvest date was November 3, 2011. The comparison is live broadcast in the open. The main implementation links are as follows: (1) Deep loosening and rotary tilling the land, and applying sufficient base fertilizer. After the land is idle and before the okra is planted, the deep loosening and rotary tilling the land, the deep loosening depth is 20-25cm, and the rotary tillage depth is 10-15cm; before the deep loosening and rotary tillage, use 150kg / mu of organic fertilizer, combined with monoammonium phosphate (total nutrient ≥ 55%) 40kg / mu and mixed evenly as a base fertilizer, evenly applied to the...

Abstract

The invention discloses a full-seedling method of okra in the moderate saline-alkali land of a coastal mud flat, and relates to the technical field of agricultural cultivation. The method comprises the first step of deep scarification and rotary tillage of the land and enough applying of base fertilizers, the second step of ditching to form micro-ridges, the third step of seed sowing and addition of water-retaining agents, the four step of spraying of weed killers and covering of a mulching film, and the fifth step of final-period management of emerged seedlings. Through certain improvement of soil fertility, temperature increasing and salt decreasing through the mulching film, salt absorption through the ridging, the addition of the water-retaining agents, water retention, fertilizer retention, moisture improvement, and moisture evaporation reduction, a low-salt zone is formed in a sowing area, and full seedlings of the okra in the moderate saline-alkali land of the coastal mud flat are achieved. The method solves the problems that the rate of emergence of the okra in the moderate saline-alkali land of the coastal mud flat is low and a full stand of seedlings is difficult, achieves the full seedlings and strong seedlings of the okra in the moderate saline-alkali land, and is economical, simple, effective, high in operability and suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of agricultural planting and cultivation, in particular to a method for sowing whole seedlings of okra in moderate saline-alkali coastal beaches. Background technique [0002] Jiangsu Province has a large population and little arable land, and arable land resources are an important factor restricting the sustainable development of agriculture in Jiangsu Province. The total area of ​​coastal tidal flats in Jiangsu Province is more than 10 million mu, ranking first in the country, of which 4.43 million mu is in the supratidal zone, and the annual growth rate is 2 The rate of growth is 10,000 mu, and coastal saline-alkali land is an important reserve resource for agricultural development in Jiangsu Province. With the rapid development of the national economy and society, the contradiction between population growth and arable land reduction has become increasingly prominent. Various saline soil resources, especi...
