How to fertilize balsam pear

When it comes to bitter gourd, many people have different views. People who like bitter gourd are naturally gourmet, but for those who don't like it, it is comparable to poison, but in any case, the nutritional price and efficacy of bitter gourd are very strong, and now the scope of adaptation is also wider and wider, and it is planted all over the country. Today we mainly come to understand how to fertilize bitter gourd.

1. Base fertilizer

Base fertilizer is the most basic condition for any kind of plant growth, so the harvest in planting balsam pear is also the same, base fertilizer we mainly use farm manure for base, and then auxiliary use of appropriate amount of nitrogen, phosphorus and potassium fertilizer, planting balsam pear per mu required farm manure is about 5,000 kg, nitrogen 40 kg, phosphorus 50 kg and 30 kg of potassium fertilizer, must be stirred evenly, and then in the soil.

2. Fertilization

The fertilizer is generally a nutrient supply in the balsam pear planting, at this time we usually combine with water, which can improve the survival rate of balsam pear seedlings, but also can be nutrients are fully absorbed by balsam pear seedlings, thus promoting special root growth. The amount of fertilizer for promoting seedlings is generally not large, mainly urea, about ten catties of urea per mu, and four or five catties of potassium fertilizer can be added, which can enhance the resistance of bitter melon seedlings.

3. Growth fertilizer

Growth fertilizer is to wait until the balsam pear seedlings grow to about 30 cm, then in order to speed up the growth rate of balsam pear seedlings, shorten its growth period, so as to bear fruit faster, so we still need to add some nitrogen fertilizer, or use fecal urine water for irrigation, at the same time can add about five pounds of urea and three or four pounds of potassium fertilizer in fecal urine water, so as to prevent melon seedlings from growing too long.

4. Flower promotion fertilizer

When balsam pear grows to a certain extent, it will enter the flowering period, usually about a week before balsam pear blossoms or when it just blooms, so that it can prolong the flowering period of balsam pear, thus improving the fruit setting rate of balsam pear. This fertilization is mainly based on phosphorus fertilizer and base fertilizer, and appropriate boron fertilizer can also be sprayed at the same time. Generally, the fertilizer allocation is carried out according to the ratio of 3:2:1.

5, strong fruit fertilizer

We all know that fruit fertilizer is applied when the fruit grows to two fingers after the fruit is set, which is used to promote the growth of bitter gourd. The fruit fertilizer is mainly phosphorus fertilizer and potassium fertilizer, and the fertilizer is applied according to ten catties of phosphorus fertilizer and eight catties of potassium fertilizer per mu. Secondly, during this period, appropriate foliar fertilizer can be sprayed. At the same time, some biological fertilizer specially used for fruit strengthening can be used, so that the quality of bitter gourd will not be affected under the condition of increasing yield.

6, late fertilizer

Later fertilizer is mainly in the first batch of balsam pear after harvest fertilizer basically belongs to the late fertilizer, it is mainly to prevent balsam pear seedling aging, thus reducing the yield of balsam pear, so in each balsam pear after harvest need to carry out a maintenance fertilization, mainly urea and compound fertilizer, the average per mu about 20 jin, at the same time also need to combine the use of appropriate phosphorus and potassium fertilizer, external fertilization, so that can effectively prevent premature aging of plants.
