The significance of cotton plantlet cultivation is mainly to rely on the group to win, rather than rely on the individual's play. In 2012, Hexin Guoxin Rural Technical Service General Association, Shaoxing Qichang, farmer-in-breeding farmer, took 497.5 acres of planting and planting cotton in small plants. Under unfavorable climatic conditions, he achieved a high yield of 279.2 kg per mu. Successful example.
The small plant type mentioned by the author refers to 3000-3500 mu per plant, 10-12 fruit sticks per plant, 35,000-40,000 fruit pods per mu, 15-18 per unit effective bells, and 50,000 effective bells per mu. 55,000, plant height of about 90 cm. If the mu density is 2500-3000 strains, the plant height is about 1 meter, and more than 20 plants per plant are bells, which is the middle plant type; and if the planting density is less than 2500, the plant height is about 1.2 meters, and the number of plants per plant is more than 25, that is, Large plant type.
The above three planting modes can all achieve high yields. Mainly depends on the soil fertility, the higher the fertility, the lower the density.
However, with the frequent occurrence of extremely severe weather in recent years and rising costs of planting cotton, the following benefits have been highlighted in the cultivation of small plants:
1. Relieve the stress of single-plant bolling, and it is easy to achieve high yield in middle and lower ground forces.
2. There are many main roots in the plant, and the main root is deep enough to make full use of the land.
3. Strong weather resistance and lodging resistance.
4. Appropriately topping up early to facilitate early maturing and increase the proportion of high quality cotton.
5. Avoid rough stalks and leaves, save fertilizer input.
6. To avoid the risk of late late ripening.
7. Reduce post-care, flower labor, which is conducive to the scale of cotton planting.
8. Appropriate to late broadcast, to create conditions for adding a season early crops.
9. Shorten cotton land occupation time and help reduce costs.
10. Do not basically top peach, can prevent rotten bell.
11. Reduce the frequency of treatment at the seedling stage and reduce the investment in engineering drugs.
12. The condition can be used for precision seeding, saving a large number of fixed seedlings.
Plant cultivation requires attention to the following:
1. Strongly control nitrogenous fertilizers. Base fertilizer uses calcium superphosphate instead of diammonium phosphate to consume excess nitrogen to prevent seedling growth.
2. Reduce the amount of nitrogen fertilizer, if there are signs of defertilization after topping, use foliar spray fertilizer or apply urea fertilizer after rain.
3. Controlling the fast and long period in mid-June, the main stem of the day is more than 1.5 cm in length and is firmly controlled.
4. If there are too many mu leaves, the late, weak and small plants will be firmly removed after the budding to reduce the density to 4000 or less.
5. Make sure that the upper fruit branches have more bells, big bells, and fatteners.
6. It is advisable to use varieties with shorter growth period, compact plant type, less madness, lighter rotten bells, and stronger bells.
